• Thunderbird compact is taking forever

  - by mulllhausen

  One day I came in to work and found that our development server - a Ubuntu box had a full hard disk. I did a bit of investigation using the du command and it seems like mozilla thunderbird is the major culprit. After burning off some backups, the disk was left at 94%: $ df -h Filesystem Size Used Avail Use% Mounted on /dev/sda1 895G 791G 59G 94% / none 4.0G 300K 4.0G 1% /dev none 4.0G 1.4M 4.0G 1% /dev/shm none 4.0G 140K 4.0G 1% /var/run none 4.0G 0 4.0G 0% /var/lock none 4.0G 0 4.0G 0% /lib/init/rw $ cd $ du -ch | grep [0-9]G 666G ./.thunderbird/ccsmcruu.default/ImapMail/mail.adofms.com.au 666G ./.thunderbird/ccsmcruu.default/ImapMail 667G ./.thunderbird/ccsmcruu.default 667G ./.thunderbird 2.2G ./.VirtualBox/Machines/iBike/Snapshots 2.2G ./.VirtualBox/Machines/iBike 2.2G ./.VirtualBox/Machines 2.2G ./.VirtualBox 670G . 670G total I did some reading and found that Mozilla Thunderbird does not compact files by default - i.e. all of the old emails that were sent to trash are still kept. One of the mailboxes used to get a lot of spam so I guess this accounts for the 667GB. I opened up Thunderbird to see how much space the inbox actually takes up and it turns out to be approximately 500MB - over 1000 times less than the stuff that has not been compacted over the years. So i right clicked on the inbox directory in the tree on the left of Thunderbird and selected 'compact'. I left it for about 12hours but even after that it still said 'compacting folder' on the status bar. I don't use Thunderbird on this PC - it belonged to a colleague who has left the company, however I do occasionally need to look through the inbox for references to the project I am working on, so deleting all traces of Thunderbird is not an option. My question is - is there any way I can monitor the progress of Thunderbird's compacting function? I would really like to know how long it is going to take. Also is there any way I can speed up the compacting process?

• I want to hit Apex SQL with a big stick

  - by Michael Stephenson

  <Whinge> Thought id just have a little whinge about this product which caused me a load of grief the other day..... So the background was that my development machine had a completely full hard disk which I needed to sort out.  Upon investigation I found the issue was that the msdb database had managed to get very large. This was caused because a long time ago (and I cant even remember why) I tried out Apex SQL.  After a few days I decided to uninstall it and thought nothing more of it.  What I didnt realise was that uninstalling it doesnt actually uninstall it (and it doesnt inform you about this), but there was still some assemblies left on my machine.  Everytime SQL Server was running it was starting the Apex SQL Connection monitor which was then running in the background and regularly recording information in the msdb database.  Over time it had recorded enough to fill the disk. The below article advises how to sort this out by removing this fully so if your having a problem then try this out:http://knowledgebase.apexsql.com/2007/08/how-to-uninstall-apexsqlconnectionmonit_09.htm Once this was sorted out its interesting to read the above article because I just dont think the approach used by the vendor of this software is a very good one.  So for the Apex team just wanted to pass on a thought: If I want to uninstall your product you should tell me if stuff is left on the machine especially if a process will be running which is going to fill my machine with useless data, </Whinge>

• SQL SERVER – Cleaning Up SQL Server Indexes – Defragmentation, Fillfactor – Video

  - by pinaldave

  Storing data non-contiguously on disk is known as fragmentation. Before learning to eliminate fragmentation, you should have a clear understanding of the types of fragmentation. When records are stored non-contiguously inside the page, then it is called internal fragmentation. When on disk, the physical storage of pages and extents is not contiguous. We can get both types of fragmentation using the DMV: sys.dm_db_index_physical_stats. Here is the generic advice for reducing the fragmentation. If avg_fragmentation_in_percent > 5% and < 30%, then use ALTER INDEX REORGANIZE: This statement is replacement for DBCC INDEXDEFRAG to reorder the leaf level pages of the index in a logical order. As this is an online operation, the index is available while the statement is running. If avg_fragmentation_in_percent > 30%, then use ALTER INDEX REBUILD: This is replacement for DBCC DBREINDEX to rebuild the index online or offline. In such case, we can also use the drop and re-create index method.(Ref: MSDN) Here is quick video which covers many of the above mentioned topics. While Vinod and I were planning about Indexing course, we had plenty of fun and learning. We often recording few of our statement and just left it aside. Afterwords we thought it will be really funny Here is funny video shot by Vinod and Myself on the same subject: Here is the link to the SQL Server Performance:  Indexing Basics. Here is the additional reading material on the same subject: SQL SERVER – Fragmentation – Detect Fragmentation and Eliminate Fragmentation SQL SERVER – 2005 – Display Fragmentation Information of Data and Indexes of Database Table SQL SERVER – De-fragmentation of Database at Operating System to Improve Performance Reference: Pinal Dave (http://blog.sqlauthority.com) Filed under: PostADay, SQL, SQL Authority, SQL Index, SQL Performance, SQL Query, SQL Server, SQL Tips and Tricks, T SQL, Technology, Video

• Read only file system

  - by Jack Moon

  I'm running Ubuntu 12.10, Upon opening any shell I get the following error: /home/jack/.rbenv/libexec/rbenv-init: line 87: cannot create temp file for here-document: Read-only file system I realised this wasn't simply a rbenv issue, as any file I try to write to returns an error saying the system is Read-only. I don't know how else to describe my problem, each time I boot up the system goes through a disk check, where it supposedly fixes several errors in my disk. Here is my /etc/fstab # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc nodev,noexec,nosuid 0 0 # / was on /dev/sda1 during installation UUID=1cc4b2ab-a984-4516-ac25-6d64f5050244 / ext4 errors=remount-ro 0 1 # swap was on /dev/sda5 during installation UUID=4e0dfeae-701a-43ce-b5c6-65f15ab3d8e3 none swap sw 0 0 The entire file system is read-only. I've tried the following sudo fsck.ext4 -f /dev/sda1 which gave the following (shortened) output /dev/sda1: ***** FILE SYSTEM WAS MODIFIED ***** /dev/sda1: ***** REBOOT LINUX ***** /dev/sda1: 1257080/45268992 files (1.0% non-contiguous), 50696803/181051904 blocks

• Using Microsoft's Chart Controls In An ASP.NET Application: Serializing Chart Data

  In most usage scenarios, the data displayed in a Microsoft Chart control comes from some dynamic source, such as from a database query. The appearance of the chart can be modified dynamically, as well; past installments in this article series showed how to programmatically customize the axes, labels, and other appearance-related settings. However, it is possible to statically define the chart's data and appearance strictly through the control's declarative markup. One of the demos examined in the Getting Started article rendered a column chart with seven columns whose labels and values were defined statically in the <asp:Series> tag's <Points> collection. Given this functionality, it should come as no surprise that the Microsoft Chart Controls also support serialization. Serialization is the process of persisting the state of a control or an object to some other medium, such as to disk. Deserialization is the inverse process, and involves taking the persisted data and recreating the control or object. With just a few lines of code you can persist the appearance settings, the data, or both to a file on disk or to any stream. Likewise, it takes just a few lines of codes to reconstitute a chart from the persisted information. This article shows how to use the Microsoft Chart Control's serialization functionality by examining a demo application that allows users to create custom charts, specifying the data to plot and some appearance-related settings. The user can then save a "snapshot" of this chart, which persists its appearance and data to a record in a database. From another page, users can view these saved chart snapshots.

• HP ProBook 4720s UEFI boot only manually into 12.04

  - by HainjeDAF

  I'm trying to get UEFI boot on my ProBook 4720s. Because I swapped the HDD for a SSD I had a blank canvas to start. The 12.04 Live DVD refuses to boot into UEFI, as do Alternate and desktop CD's. However, when I make a 16Gb flashdrive into a live FS using the bootdisk tool in ubuntu, I can boot from USB, manually into UEFI mode. It even sidesteps to DVD as medium when I boot from USB with 12.04 Live DVD present. I installed a GPT partitiontable with part 1, label EFI, fs FAT32, flag BOOT, mounts at /boot/efi part 2, label Linux-ROOT, fs ext4, no flags, mounts at / part 3, label Linux-SWAP, fs swap, no flags, mounts as swap So far, My system refuses to boot from harddrive by itself. I have to select "Boot from EFI file" and manually browse to (HD0,GPT1)\EFI\ubuntu\grubx64.efi any other option ends in "no system disk, please insert boot disk" I tried installing BURG, but that merely enforces non-efi boot. I tried most of the solutions I could find, but one says \EFI\grub\grub.cfg next says \EFI\ubuntu\ubuntu,cfg I'm confused and getting frustrated. How do I correctly install Ubuntu 12.04 in UEFI mode on this machine???

• Unable to install updates on 14.04 LTS

  - by Mike

  I have been getting update notifications for a few weeks now but whenever I attempt to install them I get this message; The upgrade needs a total of 74.6 M free space on disk '/boot'. Please free at least an additional 29.8 M of disk space on '/boot'. Empty your trash and remove temporary packages of former installations using 'sudo apt-get clean'. First of all I don't have permission to access /boot (don't know why as its a standalone machine and i'm the only user). Secondly, I emptied the trash; Thirdly, I launched Terminal and entered sudo apt-get clean I was a asked for a sudo password. I entered my system password. Re-entered sudo apt-get clean. The cursor stopped blinking - I assumed it was doing it's "thing". I let it go for about 10 minutes then exited Terminal. Tried to install the updates but just got the same message. Is there something i'm ignorant of?

   How to open a .VDI Virtual MachineSometimes someone share with us one Virtual machine with extension .VDI, after that we can wonder how and what with?Well the answer is... It is a VirtualBox - Virtual Machine. If you have not downloaded it you can do this easily, just follow this post.http://listeningoracle.blogspot.com/2010/04/que-es-virtualbox.htmlorhttp://oracleoforacle.wordpress.com/2010/04/14/ques-es-virtualbox/Ok, Now with VirtualBox Installed open it and proceed with the following:1. Open the Virtual File Manager. 2. Click on Actions ? Add and select the .VDI fileClick "Ok"3.  A new Virtual machine will be displayed, (in this Case, an OEL5 32GB Virtual Machine is available.)4. This step is important. Once you have open the settings, under General option click the advanced settings. Here you must change the default directory to save your Snapshots; my recommendation set it to the same directory where the .Vdi file is. Otherwise you can have the same Virtual Machine and its snapshots in different paths.5. Now Click on System, and proceed to assign the correct memory and define the processors for the Virtual machine. Note: Enable  "Enable IO APIC" if you are planning to assign more than one CPU to the Virtual Machine.6. Associated the storage disk to the Virtual machineThe disk must be selected as IDE Primary Master. 7. Well you can verify the other options, but with these changes you will be able to start the VM. Note: Sometime the VM owner may share some instructions, if so follow his instructions.8.

• Restoring an Ubuntu Server using ZFS RAIDZ for data

  - by andybjackson

  Having become disillusioned with hacking Buffalo NAS devices, I've decided to roll my own Home server. After some research, I have settled on an HP Proliant Microserver with Ubuntu Server and ZFS (OS on 1 Ext4 disk, Data on 3 RAIDZ disks). As Joel Spolsky and Geoff Atwood say with regards to backup, I can't rest until I have done a restore in all of the failure scenarios that I am seeking to protect against. Q: How to configure Ubuntu Server to recognise a pre-existing RAIDZ array? Clearly if one of the data disks die - then that is a resilvering scenario, which is well documented. If two of the data disks die, then I am into regular backup/restore land. If the OS dies and I can restore, also an easy scenario. But if the OS dies and I can't restore, then I need to recreate an Ubuntu server. But how do I get this to recognise my RAID-Z array? Is the necessary configuration information stored within and across the RAIZ array and simply need to be found (if so, how)? Or does it reside on the OS ext4 disk (in which case how do I recreate it)?

• Git-based storage and publishing, infrastructure advice

  - by Joel Martinez

  I wanted to get some advice on moving a system to "the cloud" ... specifically, I'm looking to move into some of Windows Azure's managed services, as right now I'm managing a VM. Basically, the system operates on some data stored in a github git repository. I'll describe the current architecture: Current system (all hosted on a single server): GitHub - configured with a webhook pointing at ... ASP.NET MVC application - to accept the webhook from git. It pushes a message onto ... Azure service bus Queue - which is drained by ... Windows Service - pulls the message from the queue and ... Fetches the latest data from the git repository (using GitLib2Sharp) onto the local disk and finally ... Operates on the data in git to produce a static HTML website hosted/served by IIS. The system works really well, actually ... but I would like to get out of the business of managing the VM, and move to using some combination of Azure web and worker roles. But because the system relies so heavily on the git repository on the local filesystem, I'm finding it difficult to figure out how to architect in the cloud. I know you can get file system access, so in theory I could just fetch the repository if there's nothing on disk ... but the performance/responsiveness of the system sort of depends on the repository being available and only having to fetch diffs, which is relatively quick. As opposed to periodically having to fetch the entire (somewhat large) git repository if the web or worker role was recycled, or something. So I would love some advice on how you would architect such a system :) Ultimately, the only real requirement is to be able to serve HTML content that's been produced from the contents of a git repository (in a relatively responsive manner, from a publishing perspective) ... please feel free to ask any clarifying questions if there's something I omitted. Thanks!

  - by The Geek

  Have you ever been browsing through photos or videos on your PC, and noticed that the thumbnails weren’t showing up properly? Sometimes they get corrupted, and you can quickly rebuild them to fix the problem. Just for some background, let’s walk through what we’re talking about. Normally, when you’re browsing around your files, you’ll see thumbnails for pictures and videos that you are viewing. These thumbnails are all generated, and stored in a cache to make browsing files faster. But sometimes… the cache gets corrupted, and we need to rebuild them. Here’s an example of what happens when it goes out of whack… Rebuilding the Windows 7 Thumbnail Cache All you have to do is open up Disk Cleanup through the start menu search box (just type in disk cleanup to find it) Just make sure that Thumbnails is checked, and then click OK to run through the cleaning process.

• Grid Infrastructure Management Repository (GIMR) database now mandatory in Oracle GI 12.1.0.2

  - by Mike Dietrich

  During the installation of Oracle Grid Infrastructure 12.1.0.1 you've had the following option to choose YES/NO to install the Grid Infrastructure Management Repository (GIMR) database MGMTDB: With Oracle Grid Infrastructure 12.1.0.2 this choice has become obsolete and the above screen does not appear anymore. The GIMR database has become mandatory.  What gets stored in the GIMR? See the documentation here See the changes in Oracle Clusterware 12.1.0.2 here: Automatic Installation of Grid Infrastructure Management Repository The Grid Infrastructure Management Repository is automatically installed with Oracle Grid Infrastructure 12c release 1 (12.1.0.2). The Grid Infrastructure Management Repository enables such features as Cluster Health Monitor, Oracle Database QoS Management, and Rapid Home Provisioning, and provides a historical metric repository that simplifies viewing of past performance and diagnosis of issues. This capability is fully integrated into Oracle Enterprise Manager Cloud Control for seamless management. Furthermore what the doc doesn't say explicitly: The -MGMTDB has now become a single-tenant deployment having a CDB with one PDB This will allow the use of a Utility Cluster that can hold the CDB for a collection of GIMR PDBs When you've had already an Oracle 12.1.0.1 GIMR this database will be destroyed and recreated Preserving the CHM/OS data can be acchieved with OCULMON to dump it out into node view The data files associated with it will be created within the same disk group as OCR and VOTING  In a future release there may be an option offered to put in into a separate disk group Some important MOS Notes: MOS Note 1568402.1FAQ: 12c Grid Infrastructure Management Repository, states there's no supported procedure to enable Management Database once the GI stack is configured MOS Note 1589394.1How to Move GI Management Repository to Different Shared Storage(shows how to delete and recreate the MGMTDB) MOS Note 1631336.1Cannot delete Management Database (MGMTDB) in 12.1 -Mike

• Restoring GRUB2 on Software RAID 0 after Windows 7 wiped it using Ubuntu 10.10 LiveCD

  - by unknownthreat

  I have installed Ubuntu 10.10 on my system. However, I need to install Windows 7 back, and I expect that it would alter GRUB and it did. Right now, my partition on my Software RAID 0 looks like this: nvidia_acajefec1 is Ubuntu 10.10 and nvidia_acajefec3 is Windows 7. I've been following some guides around and I am always stuck at GRUB not able to detect the usual RAID content. I've tried running: sudo grub > root (hd0,0) GRUB complains it couldn't find my hard disk. So I tried: find (hd0,0) And it complains that it couldn't find anything. So I tried: find /boot/grub/stage1 It said "file not found". Here's the text from the console: ubuntu@ubuntu:~$ grub Probing devices to guess BIOS drives. This may take a long time. [ Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists the possible completions of a device/filename. ] grub> root (hd0,0) root (hd0,0) Error 21: Selected disk does not exist grub> find /boot/grub/stage1 find /boot/grub/stage1 Error 15: File not found Fortunately, I got one person suggesting that what I've been trying to do is for GRUB Legacy, not GRUB2. So I went to the suggested website, ** (http://grub.enbug.org/Grub2LiveCdInstallGuide) **try to look around, and try: ubuntu@ubuntu:~$ sudo fdisk -l Unable to seek on /dev/sda This is just the step 2 of the instruction in the http://grub.enbug.org/Grub2LiveCdInstallGuide and I cannot proceed because it cannot seek /dev/sda. However, ubuntu@ubuntu:~$ sudo dmraid -r /dev/sdb: nvidia, "nvidia_acajefec", stripe, ok, 488397166 sectors, data@ 0 /dev/sda: nvidia, "nvidia_acajefec", stripe, ok, 488397166 sectors, data@ 0 So what now? Do you have an idea for how to make fdisk see my RAID array on live cd (Ubuntu 10.10)? Honestly, I am lost, very lost in trying to restore GRUB2 on this software RAID 0 system right now.

• SQL SERVER – Finding Size of a Columnstore Index Using DMVs

  - by pinaldave

  Columnstore Index is one of my favorite enhancement in SQL Server 2012. A columnstore index stores each column in a separate set of disk pages, rather than storing multiple rows per page as data traditionally has been stored. In case of the row store indexes multiple pages will contain multiple rows of the columns spanning across multiple pages. Whereas in case of column store indexes multiple pages will contain (multiple) single columns.  Columnstore Indexes are compressed by default and occupies much lesser space than regular row store index by default. One of the very common question I often see is need of the list of columnstore index along with their size and corresponding table name. I quickly re-wrote a script using DMVs sys.indexes and sys.dm_db_partition_stats. This script gives the size of the columnstore index on disk only. I am sure there will be advanced script to retrieve details related to components associated with the columnstore index. However, I believe following script is sufficient to start getting an idea of columnstore index size.  SELECT OBJECT_SCHEMA_NAME(i.OBJECT_ID) SchemaName, OBJECT_NAME(i.OBJECT_ID ) TableName, i.name IndexName, SUM(s.used_page_count) / 128.0 IndexSizeinMB FROM sys.indexes AS i INNER JOIN sys.dm_db_partition_stats AS S ON i.OBJECT_ID = S.OBJECT_ID AND I.index_id = S.index_id WHERE  i.type_desc = 'NONCLUSTERED COLUMNSTORE' GROUP BY i.OBJECT_ID, i.name Here is my introductory article written on SQL Server Fundamentals of Columnstore Index. Create a sample columnstore index based on the script described in the earlier article. It will give the following results. Please feel free to suggest improvement to script so I can further modify it to accommodate enhancements.

• Can't boot Ubuntu 12.04 from external Hard Drive using Mac

  - by Catgirl the Crazy

  Recently, I upgraded the RAM and hard drive on my Early 2008 Macbook to improve the performance. Rather than throw away the old hard drive, I bought an enclosure for it to turn it into an external hard drive, and, since all the data was migrated to my new drive, I decided to install Ubuntu on it for funsies (note: I am a near-total Ubuntu n00b). My first attempt to install Ubuntu didn't work (it gave me errors about not being able to find the BIOS or something), but my second attempt finished successfully (can't remember what, if anything, I did different). However, when I plug the external drive into my Macbook, it gives me a message saying it can't read the disk. Moreover, when I go into the Startup Manager (i.e.: what you get when you turn on the Macbook while holding the option key), the external drive is not one of the available startup disks. I thought this might be because I have an older Macbook, so I tried booting it with my mom's Late 2011 Macbook, and got the same results. Then I tried booting it through my dad's Dell laptop that runs Windows 7, and that time it worked. This is really counter intuitive to me, since the hard drive originally came from a Macbook, so if anything you'd think it would be less compatible with the Windows laptop than the Macbook. In case it helps, here's a link to a picture of how I set up the partition table while doing the install (not shown there is the fact that I checked the "Format?" box next to the /boot partition, since it gave me a warning when I tried to continue the installation without doing so) Anyone have any clue at all? If it helps, the hard drive I'm using is a 120GB 5400-rpm Serial ATA hard disk drive.

• Error mounting: mount exited with exit code 13

  - by Mike Williamson

  I keep a windows partition on my laptop for the occaisional bit of Photoshop work. A while ago I noticed that Windows had disappeared from my grub boot menu and when I try to mount the windows partion, my system hangs for a bit and then I get this: Unable to mount 105 GB Filesystem Error mounting: mount exited with exit code 13: ntfs_attr_pread_i: ntfs_pread failed: Input/output error Failed to calculate free MFT records: Input/output error NTFS is either inconsistent, or there is a hardware fault, or it's a SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows then reboot into Windows twice. The usage of the /f parameter is very important! If the device is a SoftRAID/FakeRAID then first activate it and mount a different device under the /dev/mapper/ directory, (e.g. /dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation for more details. It seems that chkdsk is a windows command but since I can't boot into windows (since its the windows partition that is the problem) I'm not sure what to do. Here is the output of fdisk to give you the lay of the land: Disk /dev/sda: 250.1 GB, 250059350016 bytes 255 heads, 63 sectors/track, 30401 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x98000000 Device Boot Start End Blocks Id System /dev/sda1 1 10199 81923436 83 Linux /dev/sda2 * 10200 22947 102398310 7 HPFS/NTFS /dev/sda3 22948 29164 49938052+ 83 Linux /dev/sda4 29165 30401 9936202+ 5 Extended /dev/sda5 29165 30401 9936171 82 Linux swap / Solaris Any guidance would be appreciated!

• No "Choose OS" screen after co-installation of Ubuntu 12.04

  - by Léon McGregor

  I don't have any technical knowledge of Ubuntu but wanted to install it on a partition. Step-by-step of what i did. used disk management in windows 7 to clear 50gb of space used a usb live ubuntu 12.04 installer in custom install mode used the installer's built in disk manager to set up 2gb swap space and 48gb ext4 space ran installation, with option to copy over documents and settings from windows 7 restarted after completion. After this, my computer automatically loads ubuntu 12 and skips the option to load windows 7. i know the files are still there, as i can see them in the file manager. When trying to fix with the win7 installer dvd it tries to repair the OS in drive [D:] i.e. it recognises the disc itself as the OS and ignores the [c:] files. I think, after browsing around here, similar problems suggest this is a problem with the boot loader, but if the win7 dvd won't work, then i don't have any way to fix this. does anyone know of a way to force the computer to show a "choose OS" screen?

• Ubuntu 13.10 installed and worked, but now not working

  - by San

  I have a HP G7000 laptop. I updated/upgraded from 13.04 to 13.10, after the software updater recommended I upgrade. I have duel booting system with Windows Vista. The system was working for the past two days, but I start getting the errors below, after selecting Ubuntu in Grub Menu on startup and at the splash screen it says "Press S to Skip or M for manual configuration" Pressing S gives a black screen and m takes you the errors below. Windows boots and works fine after selection in the Grub Menu. [ 15.235703] EXT3-fs (sda5): error: unrecognized mount option "discard" or missing value. [ 16.788072] [drm:intel_pipe_config_compare] *ERROR* mismatch in adjusted_mode flags [expected 2, found 0] [ 20.860071] [drm:intel_pipe_config_compare] *ERROR* mismatch in adjusted_mode flags [expected 2, found 0] [ 20.980076] [drm:intel_pipe_config_compare] *ERROR* mismatch in adjusted_mode flags [expected 2, found 0] Root filesystem Check failed root@simamhar:~# Tried boot-repair using the LiveCD method, no luck. System still gives above error. (you can view the boot-repair log here http://paste.ubuntu.com/6287287) When I use the liveCD for 13.04 or 13.10 however, my hard disk is recognized and I can read the files. Why is it that the installation on the hard disk has stopped working and does not recognize my / ? What do the above errors mean and how can i solve them? There was no power failure before, during or after the update/upgrade process from 13.04 to 13.10. I now would like to go back to 13.04 without reinstalling afresh? Any help will be appreciated. Thanks.

• Summary of the Solaris 11 webcast's livechat QnA session

  - by Karoly Vegh

  This is a followup post to the previous summary on the "What's new with Solaris 11 since the launch" webcast. That webcast has had a chatroom for a live Questions and Answers session running. I went through the archive of those and compiled a list of some of the (IMHO) most relevant and most frequently asked questions, I'd like to share. This is the first part, covering the QnA of Session I and II of the webcast, in a followup post we can have a look of the rest of the sessions if required - let me know in the comments. Also, should you have questions, as usual, feel free to ask those there, too.  ...and here come the answered questions:  When will Exadata be based on Solaris in place of Oracle Enterprise Linux?Exadata offers both Solaris 11 or Oracle Enterprise Linux.  The choice can be made at deployment time based on your OS needs.What are all other benefits and futures avilable in solaris 11 (cloud O.S.) compared to cloud based Red Hat Linux and Windows?suggest you check out our cloud white paper for a view of this. Also the OTN Solaris 11 page has some good articles. Here are the links:  http://www.oracle.com/technetwork/server-storage/solaris11/documentation/o11-106-sol11-cloud-501066.pdf http://www.oracle.com/technetwork/server-storage/solaris11/overview/index.htmlWill 11.1 have a more complete IPS respository for Oracle and FOSS software?Yes, we are adding additional packages to the various package repositories. Since Solaris 11 was launched, both the Oracle Solaris Studio tools as well as Oracle Solaris Cluster have been made available along with numerous new FOSS packages. We will continue to be adding additional Oracle products and open source packages in the future. Will Exadata be based on Sparc in place of intel-amd x86 in next future ?We can't publically discuss futures, but we actually have a SPARC version of Exadata today, it's called SuperCluster, this is such a powerfull multipurpose system that it actually have multiple personalities built into one system: Exadata, Exalogic, and it can be a general purpose platform if you want. Have I understood this right? Livepatching KSplice-style is coming to Solaris 11 too?We're looking at that for certain types of Solaris patches in the future.Will there be a security framework like SST/JASS for Solaris 11?We can't talk about the future projects on a public forum, but we recognize the need for SST/JASS and want to address this as soon as possible. On the other side there are a whole bunch of "best practices" that are now embedded into Solaris 11 by default, so out of the box Solaris 11 should already address part of what SST/JASS gave you. (For example we did a lot of work on improving the auditing performance so that we can now have it turned on by default). On x86 can install VirtualBox in a Zone and use that to host other OSes.Yes, this was one of the first things we made sure would work when we acquired VirtualBox when we were still Sun Microsystems. If I have a Solaris 11 Control Domain on a T-series, can I run a Solaris 10 Ldom with Solaris 8 branded containers?Yes, you can.Is Oracle Solaris free or do we need to purchase?Solaris is free, the entitlement to run it comes either with a Sun system (new or historical) or for 3rd party systems the entitlement comes with a support contract. Note that for production use you will be expected to get a support contract. If you don't want to use the Solaris system (Sun or 3rd party) for production use (i.e. development) you can get an OTN license on the Oracle Technical Network website. Will encryption and deduplication both work on a share?This should work at the same time. What approaches does Solaris use to monitor usage?There are many different tools in Solaris to monitor usage. The main ones are the "stats" (vmstat, mpstat, prstat, ...), the kstat interface, and DTrace (to get details you couldn't see before). And then there are layered tools that can interface with these tools (Ops Center, BMC, CA, Tivoli, ...) Apart little-endian, big-endian how is it easy to port Solaris applications on Sparc to x86 and vice-versa ?Very easy. Except for certain hardware specific applications (those that utilize hardware specific drivers), all of the same Oracle Solaris APIs exist for all architectures. Is IPS based patching aware of the fact that zones can reside on ZFS and move from one physical server to another ?IPS is definitely aware of zones and uses ZFS to support boot environments for non-global zones in the same way that's used for the global zone. With respect to moving a zone from one physical server to another, Solaris 11 supports to the same zone attach/deattach method that was introduced in Solaris 10. Is vnic support in Ldoms planned?This is currently being investigated for a future LDOM release. Is it possible with the new patching system to build a system later with the same patch level as a system built a few months earlier?Yes, you can choose/define exactly which version should go to the system and it will always put the same bits in place. The technical answer is that you choose the version of the "entire" package you want on the system and the rest flows from there. Is it in the plans to allow zones to add/remove zpools to running zones dynamically in future updates?Work in this area is currently under investigation. Any plans to realese Solaris 11 source code? i.e. opensolaris?We currently can't comment on publicly releasing the source code. If you need/want this access please let your Oracle account team know. What about VirtualBox and Solaris11 for virtualization?Solaris 11 works great with VirtualBox, as both a client and a host system. Will Oracle DB software eventually be supplied as IPS packages? When?We don't have a date yet but this is actively being worked on. What are the new artifacts in Oracle Solaris 11 than the previous versions?There are quite a few actually. The best start is to look at our "Evaluate Solaris 11" page, and there you also can find a Transition Guide. http://www.oracle.com/technetwork/server-storage/solaris11/overview/evaluate-1530234.html So, this seems just like RedHat's YUM environment?IPS offers certain features beyond those in YUM or other packaging systems. For example, IPS works with ZFS and Solaris Boot Environments to provide a safe environment for software lifecycle management so that changes can be reverted by switching to an older boot environment. With Zones on solaris 11, can I do paravirtualitation?The great thing about zones is you don't *need* paravirtualization. You're making the same direct kernel calls that you would outside of a zone.  It's an incredibly significant performance win over hypervisor-based virtualization. Are zones/containers officially supported to run Oracle Databases?  EBIZ?Hi Calvin, the answer is yes, here is the support matrix for DB:  http://www.oracle.com/technetwork/database/virtualizationmatrix-172995.html I've found some nasty bugs in Solaris 11 (one of which today) that have been fixed in community forks (i.e., Illumos). Will Oracle ever restart collaboration with the community?We continue to work with the community, just not as open on all projects as we did before (For example IPS is an open project) and the source of more than half of the Solaris packages is posted on our opensource websites. I can't comment on what we will do in the future. And with regards to bugs please file them through the support organization and we will get them resolved. Is zpool vdev removal on-the fly now possible ?This issue is actively being investigated although we don't have a date for when this feature will be available. Is pgstat now the official replacement for corestat ?It's intended to provide similar functionality Where are the opensource website?For Oracle Solaris, visit http://www.oracle.com/technetwork/opensource/systems-solaris-1562786.html As a cloud-scale virtualization, is it going to be easier to move zones between machines? maybe even automatic in case of a hardware failure?Hi Gashaw, we already have customers that have implemented what they refer to as "flying zones" that they can move around very easily. They use Solaris Cluster to do this. What about VMware vMotion like feature?We have secure live migration with both Logical Domains on SPARC T series systems, and with Oracle VM on x86 systems. When running Solaris 10/11 on an enterprise server with a lot of zones, what are best practises commands to show the system is running fine? (has enough hardware resources). For example CPU / Memory / I/O / system load. What are the recommended values?For Solaris 11, look into the new zonestat(1M) command that provides a great deal of information about zone utilization. In addition, there is new work underway in providing additional observability in areas such as per-zone file system I/O. Java optimizations done with Solaris 11? For X86 platforms too? Where can I find more detail about this?There is lots of work that go into optimizing Java for Oracle Solaris 10 & 11 on both SPARC and x86. See http://www.oracle.com/technetwork/articles/servers-storage-dev/solarisforjavadevelop-168642.pdf What is meant by "ZFS Shadow Migration"?It's a way to migrate data from another file system to ZFS: http://docs.oracle.com/cd/E23824_01/html/E24456/filesystem-3.html Is flash archive available with S11?Flash archive is not.  There is a procedure for disaster recovery, and we're working on a modern archive-based deployment tool for a future update.  The disaster recovery tool is here: http://www.oracle.com/technetwork/articles/servers-storage-admin/o11-091-sol-dis-recovery-489183.html  You can also use Distribution Constructor to build common golden images. Will solaris 11 be available on the ODA soon?The idea's under evaluation -- we'll share your interest with the team. What steps can be taken to ensure that breaches of security are identified quickly?There are a number of tools, including the "bart" tool and "pkg verify" to ensure that software has not been compromised.  Solaris Audit can also be used to detect unauthorized access.  You can also use Immutable Zones to protect against compromise.  There are a wide variety of security tools, and I've covered only a few. What is the relation from solaris to java 7 speed optimization?There is constant work done between the Oracle Solaris and Java teams on performance optimizations. See http://docs.oracle.com/javase/7/docs/technotes/guides/vm/performance-enhancements-7.html for examples. What is the difference in the Solaris 11 installation compared to solaris 10 ? where i can find the document describing basic repository concepts ?The best place to start is: http://www.oracle.com/technetwork/server-storage/solaris11/index.html Hope you found the post useful. For questions, input, requests for the second half of the QnA, please find the comment section below.  -- charlie

• Installer doesn't display partition I want to install to

  - by Aditya

  While performing a Ubuntu 10.10 installation on my laptop, it doesn't show partitions pertaining to the PC. My PC configuration is as follows : HP Pavilion dv6 - 2020AX AMD Turion II Dual Core Mobile Processor M500 4 GB RAM OS Installed : Windows 7 500 GB Hard drive partitioned as follows : C : 227 GB (Free : 142 GB) D : 11.9 GB (Free : 1.98 GB) - Recovery F : 174 GB (Free : 18 GB) G : 50.5 GB (Free : 50.4 GB) So, I want to perform a Dual-boot installation on my PC, so that Ubuntu resides in the free disk space G:. Therefore, I started the Ubuntu 10.10 installation and select the manual partitioning feature in the installation. However, in the 'Allocate Drive Space' section of the installation, following partitions information is displayed: Partition Type Size Used /dev/sda /dev/sda1      1 MB    unknown /dev/sda2    ntfs    208 MB   unknown /dev/sda3   ntfs    244813 MB    168540 MB /dev/sda4    ntfs    255083 MB   3221 MB where /dev/sda - 500 GB So, what exactly is the problem? What is it should I do to install Ubuntu 10.10 in the G: disk space? Why are the partitions not being shown as the way they should be? Any Suggestions. Thank you for the help.
