• Dell Media Direct is rebooting my machine when it goes into sleep mode

  - by wsanville

  I've got a Dell studio 1535 laptop, which shipped w/ Vista 32 bit. I've since formatted and installed Win 7 64. Everything has been fine for months, but recently, every time I leave my machine unattended and it goes to sleep, it wakes with the Dell Media Direct splash screen, and then goes to the "Windows was not shut down properly..." dialog that asks if you want to boot safe mode/start Windows normally/etc. The stupid button is also stuck on currently, but even when it is off, the problem still occurs. From the searching I've done, I've learned that the program is installed on its own partition, but I'm fairly certain I formatted everything (see screenie of my partitions: http://www.engr.uconn.edu/~wsj05001/misc/partitions.png). How can I stop the madness?

• Reliable Linux RAID Card

  - by Chris S

  Can anyone recommend an appropriate RAID card for use under Linux (Ubuntu)? I have three Western Digital SATA drives, and would like to setup either RAID-1 or RAID-5. Software RAID has been very flakey and unreliable for me (e.g. it doesn't seem to mirror the boot partition). Unfortunately, most RAID cards I've seen online don't mention any Linux driver support. Would most cards work in Linux, or do I have to look at a select few that explicitly support Linux?

• OpenVZ: Choosing right MySQL-Server depending on host

  - by Scheintod

  What I have: Two servers running Wheezy/OpenVZ with One MySQL container on each host master/master replicated (mysql1/mysql2) Replicated DNS on each host (dns1/dns2) different web-containers on each host but regulary backuped to the other. What I want: Each container should use the "local" MySQL-Server (the one which runs on the same hardware-node). I'd like to be able to move the web-containers between the to hosts. Each container should choose the MySQL-Server (semi) automatically. This scheme should continue working if one host is down. What I tried: Currently I'm keeping track on which container should run on which host by DNS entries which are queries by scripts e.g. for questions like: "Which container should be backuped on/to which host." For choosing the right MySQL server I have one extra entry like "mysql.container_abc" which resolves to either mysql1/mysql2. So in the applications in the container I can use "mysql.container_abc" for e.g. mysql_connect and if I want to move the container around I just need to change the dns. Now I notices one problem with this approach: Every mysql_connect generates one DNS query because the dns is not cached and this slows the request down unnecessarily. What I would like better: Some way of passing the information on which host we are running to the container and using it directly instead of using DNS. E.g. some way of setting a custom /etc/hosts entry in the container. Or any other great idea. Doesn't have to include DNS but shouldn't require to much special "magic" inside the container.

• Ubuntu: One or more of the mounts listed in fstab cannot ye be mounted

  - by Phuong Nguyen

  I was enjoying a Movie when my Ubuntu suddenly hung. At the next reboot, here is the message: One or more of the mounts listed in /etc/fstab cannot yet be mounted: /home: waiting for /dev/disk/by-uuid/.... Press ESC to enter a recovery shell. Problems: When I enter recovery shell, I don't know that to do. If I press Ctrl+D, then the message above will reappear. What should I do? I checked with Ubuntu Live CD and my partition looks OK. I have 2 separate partitions for / and /home

• Suggestion for boot manager in external hard disk

  - by Korrupzion

  Hi, I just bought an 1TB External Hard drive with eSATA, USB, FW400/800 (LaCie if you are interested). I already put the windows 7 installation in a FAT32 active partition so i can plug the HDD via USB, since my notebook or other computers doesn't support boot via eSATA commonly, and it works. Now i want to do more partitions so i'm looking for a way to have a boot manager as active partitions that allows me to boot from different partitions in my HDD (win7, ubuntu installations for example) I want to know if you know any software to do this or you already have this system. Thanks and sorry i have too many grammar errors because english is not my native language :)

• How to perform fresh linux install while preserving software raid and user accounts

  - by slayton

  I have a system with two software raid arrays. The OS is Ubuntu 9.04 and is no longer receiving updates. I'd like to update the system to 12.04 rather than trying to do the automatic update from 9.04-> 9.10-> ... -> 12.04. My main drive has 2 partitions that are mounted at / and /home. Is it possible to do a fresh install of linux to the partition where / is mounted while preserving user accounts and preferences (such as passwords, home dir locations, etc...)? Additionally what do I need to do to keep my software raid array intact following the OS re-install?

• What is the best way to create RAID 1?

  - by user3125731

  I'm looking for a way to create the RAID 1 array without losing my data on CentOS. Here's my situation: I've got a web server running on CentOS. There is one VG partition with few LV volumes. I bought a second HDD (the same model and size as the first one) and I want to create the RAID 1 configuration. I can't just shut down this server for more than an hour because my clients will be disappointed. I need to do this as quickly as possible with minimal risk of data loss.

• Is there a way to do a Windows 7 repair install when you are unable to start/boot Windows 7?

  - by irrational John

  My understanding is that the only way to perform a "repair install" in Windows 7 is to run the install setup.exe within the Windows 7 installation you want to repair. This seems a little brain dead to me since usually the reason I wanted to perform the repair install was because the existing installation was so broken that I could no longer boot and use it. It seems Microsoft is saying my only option in that case is to do a clean install and then reinstall all my apps. So I'm wondering if anyone knows of a way to perform a Windows 7 repair install ... one that preserves your existing OS settings and application installs ... on a Windows 7 partition that cannot be booted.

• Seasgate GoFlex NAS + Horrible Speed = Bad Experience

  - by Jon H

  I am having issues with transfer speeds from my desktop PC to my NAS. I have my NAS hooked up to a Gigabit Gateway as well as my Desktop with Cat 5e. I see up to 4.0 MB/Second Transfer Rates, the normal is about 2.5 MB/Seconds. There is 3 Partitions on my NAS, Public, Private, Backup. When I transfer from Private to Public I see the speeds above. If its under the same partition almost instant. I was wondering if the speeds I am seeing is in due to my Computer or the NAS. I was looking into building my own Media Server in due to these horrible speeds. Is their anything I can do in the mean time to speed this up? Motherboard = M3970AM-HP (Angelica) Processor = AMD FX 6100 Ram = 10GB PC3-10600 MB/sec Hard Drive (1) = 1.5TB SATA 3.0GB 5400RPM Hard Drive (2) = 120GB SATA SSD NAS = Seagate 3TB Go Flex Home Connection (1) = 1000 Base T Connection (2) = Wireless N

• Encryption of external HDD -- accessible from windows without installation

  - by Rainer

  I would like to use encryption on my external HDD but I would like to be able to access the encrypted data from Windows as well. As suggested in other questions, TrueCrypt is one option here, or I am using momentarily encfs, which is not available for Windows. But my question goes further: I would like to be able to access the encrypted partition from Windows without installation as I will be using it from different Windows machines for which I have no administrator access. My main OS is Linux and I have full root access to that computer. Is there a full disk or file based encryption which I can use cross platform and which does not require installation under Windows? ADDITION: It seems that TrueCrypt provides a portable mode which fulfills my requirements partly: http://www.truecrypt.org/docs/?s=truecrypt-portable, but still the TrueCrypt driver needs to be installed by an administrator... pitty Thanks

• Backup and restore.

  - by Xavierjazz

  I have a Thinkpad T60 with a 150GIg internal hard drive. XP Pro SP3. I also have a similar hard drive that used to be in another laptop connected via USB. It contains only data. I have cleared out a lot of duplicate files and now would like to back both up. I have Retrospect and a brand new 1Tbyte drive for this purpose. Can I back up the whole computer (both drives) but, in case only one fails, can I just restore that drive or do I have to restore both drives at the same time? I don't understand how partitions work so might I be able to partition the 1T drive and restore each smaller drive independently? Thanks.

• Gentoo Linux -> Ubuntu: Can I Preserve My LVM/RAID Devices, Or Do I Need To Reformat?

  - by Eddie Parker

  Hello: I've got a Gentoo box that I'm interested in switching over to an Ubuntu box. I currently have the partitions laid out using a mixture of RAID (mdadm) and LVM2, as specified in this document [1]. Ideally I'd like to just wipe out the non /home partition, as it's got data I'd like to keep. Is it possible to reuse the current setup, or do I need to restart? vgdisplay, vgchange -a y, etc don't yield any results from the Ubuntu LiveCD, and I'm wary to run any commands that might wipe my data. Your help would be appreciated. [1] http://www.gentoo.org/doc/en/gentoo-x86+raid+lvm2-quickinstall.xml

• Large temp files created in Windows Server 2003 temp folder

  - by BlueGene

  I'm managing a Windows Server 2003 with around 30 GB space in primary partition. A couple of times the server has crashed with error message saying that the C: drive is full. After searching folders to free up space, I found that lot of temp files being created in C:\WINNT\Temp and some of them of enormous size with more than 2GB. The temp files have common name, Efs###.tmp. Since we encrypt files frequently using Windows's EFS, I initially suspected Windows encryption. But after reading the documentation, I found that Efs###.tmp are in fact created by EFS but they are created only under the folder which you're currently encrypting, not in Temp folder. This looks very strange since Efs##.tmp files shouldn't be created under C:\WINNT\Temp unless someone tried to encrypt that Temp folder itself. The server has Tivoli Backup client. Could that be messing with windows Encryption? Can anyone shed some light on what could be causing the issue?

• VirtualBox, physical disks, and snapshots

  - by noamtm

  I have an Ubuntu guest installed on a raw HDD (entire disk, not a partition). It runs just fine under WinXP. In addition, I was able to boot directly into it (using the BIOS boot-device selector). At some point, I have created a snapshot of the VM. I have made some changes since then. Today, after a long time, I tried booting into the "VM" disk. It worked, but all the data there is pre-snapshot (or, rather, frozen at the snapshot). Can I somehow merge the changes since I took the snapshot into the physical state?

• Getting kernel errors when manually mounting VirtualBox shared folders

  - by Ross

  Updated: I've rephrased this problem as I understand it a bit more now (and have encountered another problem). I'm using a Fedora 15 guest on a Windows 7 host using VirtualBox. I am trying to mount a partition on the host PC as a shared folder for use in the guest. The folder appears in /media and is accessible when I use the auto-mount feature when setting up the shared folder, but when I attempt to mount without auto-mount I get the following error: $ sudo mount.vboxsf data /mnt/host_data /sbin/mount.vboxsf: Could not add an entry to the mount table.: Invalid argument In addition a popup appears (part of Fedora/GNOME) reporting a crash in the kernel package: WARNING: at lib/list_debug.c:26 __list_add+0x3e/0x81() However the shared folder seems to work, I can certainly browse it (although everything seems to be executable, probably down to a Windows host). Is there something wrong with what I'm doing or is this a bug (and in which case should it be reported to the Linux Kernel team or VirtualBox)?

• How to rename a BTRFS subvolume?

  - by hochl

  I have a BTRFS filesystem with a set of subvolumes in it. So far so good. I need to change the name of a subvolume, unfortunately the btrfs program does not allow me to rename a subvolume. Searching with Google has yielded some results, one said I can just mv, the other said I can just snapshot to a new name and delete the old subvolume. Before I crash my partition and have to reload it from the backup (it's quite large), my question is: What is the currently best way to rename a subvolume? Is it ok to just mv it, or will it invalidate some internal structures? Is making a new snapshot and removing the old subvolume the way to go, or has this some drawbacks? I know everything is still experimental, but for my purposes it has been working quite well (so far, and I have incremental backups for each day).

• Windows 7 Bootcamp to see data doubler SATA SSD in Optical Bay Connector

  - by bumble_bee_tuna

  Hi I purchased a OWC data doubler http://eshop.macsales.com/item/OWC/DDAMBS0GB/ ... Long story short it lets you add a second HD to your macbook pro in place of the cd/dvd drive (which is useless anyway, impossible to get stuff out when stuck). My current setup is 600gb intel SSD bootdrive 100gb partition for OSX / 500gb for Windows 7 Prof from Bootcamp (use 99 % of time). My desire is to have a second 300gb SSD to run disk intensive VM's off of. So I added a second 300gb intel SSD (again, NO desire to boot off of) on the sata optical port. I can see the drive no problem if I boot in to OSX, however, can't see it in disk management on Win7 ??? Any ideas similar experience ... Funny thing is I can see it in "Device Manager Disk Drivers" but not Disk Management ??? Also no I don't want to use Fusion/Parallels this is a waste of resources for me.

• Identify SATA hard drive

  - by Rob Nicholson

  Very similar question to: Physically Identify the failed hard drive But for Windows 2003 this time. Scenario: Four identical SATA hard drives plugged into motherboard (no RAID controller here) Configured as single drive in Windows as a spanned volume One of them is starting to fail with error "The driver detected a controller error on \Device\Harddisk3" How do you cross-reference Harddisk3 to the physical SATA connection on the motherboard so you know which drive to replace? I know replacing this drive will trash the spanned array requiring it to be rebuilt anyway so my rough and ready solution is: Delete the spanned partition Create individual partitions on each drive labelled E: F: G: and H: and work out which one is Harddisk3 Power down, remove each disk one at a time, power-up until the drive letter disappears But this seems a rather crude method of identifying the drive. The SATA connectors will be numbered on the motherboard but I appreciate this might not cross-match to what Windows calls them. Thanks, Rob.

• Where are Wireless Profiles stored in Ubuntu

  - by LonnieBest

  Where does Ubuntu store profiles that allow it to remember the credentials to private wireless networks that it has previously authenticate to and used? I just replaced my Uncle's hard drive with a new one and installed Ubuntu 10.04 on it (he had Ubuntu 9.10 on his old hard drive. He is at my house right now, and I want him to be able to access his private wireless network when he gets home. Usually, when I upgrade Ubuntu, I have his /home directory on another partition, so his wireless profile to his own network persists. However, right now, I'm trying to figure out which .folder I need to copy from his /home/user folder on the old hard drive, to the new hard drive, so that he will be able to have wireless Internet when he gets home. Does anyone know with certainty, exactly which folder I need to copy to the new hard drive to achieve this?

• Mount encrypted hfs in ubuntu

  - by pagid

  I try to mount an encrypted hfs+ partition in ubuntu. An older post described quite good how to do it, but lacks the information how to use encrypted partitions. What I found so far is: # install required packages sudo apt-get install hfsprogs hfsutils hfsplus loop-aes-utils # try to mount it mount -t hfsplus -o encryption=aes-256 /dev/xyz /mount/xyz But once I run this I get the following error: Error: Password must be at least 20 characters. So I tried to type it in twice, but that results in this: ioctl: LOOP_SET_STATUS: Invalid argument, requested cipher or key (256 bits) not supported by kernel Any suggestions? Thx Edit: One thing I'm not sure about is whether I use the right password. My assumption is that it is my default one for these situations. But I'm not sure whether Max OSX choose another password (internally) for that.

  i have a seagate 3.5" 500GB SATA2 HDD that i put in a USB case (vantec) that failed recently. symptoms: at first, it started except that attempts made to browse certain folders resulted in "Data Error (Cyclic Redundancy Check)". then when i tried restarting the hdd, then i got a RAW partition, and windows 7 said i need to format it. i also tried using a desktop to connect to the HDD directly using SATA, windows 7 stuck at "starting windows" for abt half hour b4 i gave up on it. in the BIOS, it seems to detect the HDD model correctly, something like STA3500xxx something like that i also tried using TestDisk as suggested by jaclaz on MSFN and it did not find any partitions what could i do now?

• Setting up SSL on JBoss 5

  - by socal_javaguy

  How can I enable SSL on JBoss 5 on a Linux (Red Hat - Fedora 8) box? What I've done so far is: (1) Create a test keystore. (2) Placed the newly generated server.keystore in $JBOSS_HOME/server/default/conf (3) Make the following change in the server.xml in $JBOSS_HOME/server/default/deploy/jbossweb.sar to include this: <!-- SSL/TLS Connector configuration using the admin devl guide keystore --> <Connector protocol="HTTP/1.1" SSLEnabled="true" port="8443" address="${jboss.bind.address}" scheme="https" secure="true" clientAuth="false" keystoreFile="${jboss.server.home.dir}/conf/server.keystore" keystorePass="mypassword" sslProtocol = "TLS" /> (4) The problem is that when JBoss starts it logs this exception (during start-up) (but I am still able to view everything under http://localhost:8080/): 03:59:54,780 ERROR [Http11Protocol] Error initializing endpoint java.io.IOException: Cannot recover key at org.apache.tomcat.util.net.jsse.JSSESocketFactory.init(JSSESocketFactory.java:456) at org.apache.tomcat.util.net.jsse.JSSESocketFactory.createSocket(JSSESocketFactory.java:139) at org.apache.tomcat.util.net.JIoEndpoint.init(JIoEndpoint.java:498) at org.apache.coyote.http11.Http11Protocol.init(Http11Protocol.java:175) at org.apache.catalina.connector.Connector.initialize(Connector.java:1029) at org.apache.catalina.core.StandardService.initialize(StandardService.java:683) at org.apache.catalina.core.StandardServer.initialize(StandardServer.java:821) at org.jboss.web.tomcat.service.deployers.TomcatService.startService(TomcatService.java:313) I do know that's there's more to be done to enable full SSL client authentication....

• Win7 backup fails with "The system cannot find the file specified" 0x80070002 - has worked before

  - by Thorbjørn Ravn Andersen

  I have a 500 GB USB-disk which has been used as a backup device for a few years now, but now fails without telling me why. This is a Dell box with Intel USB-controllers (so the NVIDEA problem does not apply here). I have previously had problems with a Git package marking a non-existent directory for backup (adding it make the backup succeede). The inaccessible boot partition problem described in Windows Backup fails with 0x80070002: "The system cannot find the file specified" does not apply to me. I would appreciate hints on where to look to identify why my backup fails so I can fix it.
