• Indefinite hang when restoring SQL 2005 database on a SQL 2008 server in EC2

  - by erinloy

  I'm trying to restore a 25 GB database backup taken from a Windows 2003/SQL 2005 machine to a Windows 2008/SQL 2008 machine in the Amazon EC2 cloud, using a .bak file and the SQL Management Studio. SQL Management Studio reports the restore reaches 100% complete, and then just hangs indefinitely (24+ hours) using a lot of CPU, until I restart the SQL Server service. Upon restart, SQL again uses a lot of CPU activity for what seems to be an indefinite amount of time, but the DB never comes online. Here are some details: - I have created two EBS volumes, one for DATA and one for LOGS, and I have set the default directories in SQL Server to the \DATA and \LOG directory on these respective volumes. (I wonder if the issue could be related to this, but the DB is too big to restore on the root drive.) - I have given the SQL Server user group full access to these directories. - The server can create a new empty test DB in these directories just fine, and can backup and restore the test DB. - I have tried both restoring of a .bak file and attaching directly to copies of the original .mdf/.ldf files, and the result is the same in both cases. - Both the .bak restore and the .mdf/.ldf attach occur from/to the EBS volumes. - I've also tried the above via SQL script, and "WITH RECOVERY", with no difference in the result, just less UI. - The backup contains two full text indexes. - I have to use "WITH MOVE" for most of the files in the backup. - There's nothing wrong with the backup or .mdf/.ldf files, as this works just fine on a Windows 2003/SQL 2005 machine in the Amazon EC2, but not Windows 2008/SQL 2008. - The DB is NOT marked as "Restoring" in the SQL Management Studio - it is just listed as a normal database, but throws errors when I try to do anything with it (expand the object browser tree, view properties, etc.) Any ideas?

• SuperMicro BMC on OpenSuSE Linux --cannot access from LAN

  - by Kendall

  Hi, I have an (old) SMC-001 IPMI device on an (old) X6DVL-EG2 motherboard. My problem is that I cannot access the BMC from LAN. I'm also getting some interesting output from ipmitool. First, the setup. I enable Console Redirection in the BIOS, turn BIOS Redirection after POSt to "disabled". I then modprobe'ed for ipmi_msghandler, ipmi_devintf and ipmi_si. I then found ipmi0 under /dev. So far so good. Since I want console redirection over serial, I modified /boot/grub/menu.lst: http://pastebin.com/YYJmhusQ I then modified "/etc/inittab" as follows: S1:12345:respawn:/sbin/agetty -L 19200 ttyS1 ansi Networking I set as following, using "ipmitool" ipaddr: 192.168.3.164 netmask: 255.255.255.0 defgw: 192.168.3.1 The above are correct for my environment. To test it I do: ipmitool -I open chassis power off which responds by powering off the machine. When I to access from another computer on the network, however, I get an error message: host# ipmitool -I lanplus -H 192.168.10.164 -U Admin -a chassis power status Error: Unable to establish LAN session Unable to get Chassis Power Status "Admin" seems to be a valid user name: host# ipmitool -I open user list 1 2 Admin true false true USER The interesting output from ipmitool I initially mentioned: host # ipmitool -I open lan set 1 access on Set Channel Access for channel 1 failed: Request data field length limit exceeded Also, newload4:/home/gjones # ipmitool channel info 1 Channel 0x1 info: Channel Medium Type : 802.3 LAN Channel Protocol Type : IPMB-1.0 Session Support : session-less Active Session Count : 0 Protocol Vendor ID : 7154 Get Channel Access (volatile) failed: Request data field length limit exceeded The output of "ipmitool -I open lan print 1" is here: http://pastebin.com/UZyL6yyE Any help/suggestions is greatly appreciated; I've been working with this thing for a few hours now with no success.

• VMWare ESX, storage over 2TB

  - by Phliplip

  Hi, First of, i'm a webdeveloper and my server experience lies in setting up FreeBSD servers for webserver. I'm working on a project for at photographer, and i'm hired to develop a new online photo ordering system - where user of course can view their photos :) They have a massive need of storage, thus we have bought a HP G6 and 8x1TB SATA HDD. Our plan is to install VMWare ESX 4.0, running multiple virtual machines; FreeBSD 8 for webserver and some windows servers. Allready done that. Then mount one big storage to the BSD, and share it through Samba to the WinServers. The raid is set up with an array of 2x 1TB to handle the VMs. And the rest is setup as 3 2x1TB to handle the photo-data. Thus 2.73TB for photo-data (the raids are 1+0). Now if we add a datastore in the ESX and add the 3 LUNs we can get a datastore of 2.74TB. But i don't se how i can add this datastore direct to the VM. Only the BSD VM needs access to this. Only way is to create a VirtualDisk, with a max of 2TB (8MB blocksize). This is because the datastore where we save the virtualdisk has a maximum filesize of 2TB. Then add it as a harddisk to the BSD VM. In the 'Add Harddisk' pane for the VM, i see an option for Raw Disk Management. I think this is to access the datastore or the raid directly. Only problem is that its greyed out! Can i access the datastorage directly from the BSD? Without creating and adding virtualdisk.

• How to remove a plain text protecting single quote from all the selected cells in LibreOffice Calc?

  - by Ivan

  I've imported a CSV file having the first column to be date-time values in ISO 8601 format like 2012-01-01T00:00:00.000Z for the first moment of the year 2012. Then, willing to make LibreOffice to recognize the format (as I was looking forward to plot a diagram), I've selected the column, chosen Format Cells... and entered the custom time format as YYYY-MM-DDTHH:MM:SS.000Z And this seems to work if... I edit a cell to remove a hidden single-quote from its beginning (which serves to protect a cell content from being interpreted) as all the newly formatted cells now store values like '2012-01-01T00:00:00.000Z (note the single quote - it is only visible when you edit a particular cell). And I am to do so for all the cells in the column. How can I automate this? UPDATE: I've already found a solution for the particular case of mine: it helps to set a column format to "time" in the CSV import dialogue. But I am still curious how could this be done in case I wouldn't have the original .csv data file to import but only the .ods file with the data already imported without the format specified at the import time.

• Non-functioning AutoFilter on Locked Cells in Office 2008 - works in Office 2007

  - by Sarcas

  I'm looking into a problem for someone, who works in a mixed OS environment. She has created an Excel spreadsheet in Office 2007 to act as a directory, with AutoFilter turned on for names, email addresses, departments etc. To make sure no one accidentally edits email addresses (for example), she has protected the work sheet. Accessing this worksheet on a PC running Excel 2007, everything runs as you'd expect. You can filter the sheet by any of the auto-filtered columns, and because the sheet is protected, the data integrity is guaranteed. However, if you access the sheet on a Mac running Excel 2008, you can't filter the columns. What's strange here is that the AutoFilter dropdown arrows do appear in each of the column headers as you would expect. It's just that nothing happens if you click on them. If you select one of the column header cells (say, 'First Name') and check the menu: Data-Filter, you can see that AutoFilter is ticked. As another datapoint, you also seem to be able to apply an Advanced filter to these rows on the protected sheets. Does anyone know why this might be? It seems to be a compatibility issue between Excel 2007/2008 (I know the codebase isn't the same), but I can't find any references to it in documentation or forums anywhere, and it would be good to know if there's a way around this. Thanks!

• How to repair multiple KDC an Netlogon errors

  - by Keith Sirmons

  Howdy, I have several erros in the system event log of my single Windows 2003 SP2 domain controller. Multiple member computers on the domain are listed in these errors. I am seeing two similar errors for each computer one second apart in the event log. Event ID 7 Source KDC The Security Account Manager failed a KDC request in an unexpected way. The error is in the data field. The account name was [email protected] and lookup type 0x8. followed by Event ID 7 Source KDC The Security Account Manager failed a KDC request in an unexpected way. The error is in the data field. The account name was MEMBERNAME$ and lookup type 0x8. The Lookup Types are also different, I have 0x8, 0x28, 0x0, 0x20. I am also receiving other authentication errors in the same time frame as all of the KDC errors Event ID 5722 Source NETLOGON The session setup from the computer MEMBERNAME failed to authenticate. The name(s) of the account(s) referenced in the security database is MEMBERNAME$. The following error occurred: Access is denied. I have run dcdiag /v to see if there was something wrong with Active Directory, but all tests passed. I also ran netdiag /v and it appers all of those tests ran. Any ideas on where to start for this issue? Thank you, Keith

• Can compressing Program Files save space *and* give a significant boost to SSD performance?

  - by Christopher Galpin

  Considering solid-state disk space is still an expensive resource, compressing large folders has appeal. Thanks to VirtualStore, could Program Files be a case where it might even improve performance? Discovery In particular I have been reading: SSD and NTFS Compression Speed Increase? Does NTFS compression slow SSD/flash performance? Will somebody benchmark whole disk compression (HD,SSD) please? (may have to scroll up) The first link is particularly dreamy, but maybe head a little too far in the clouds. The third link has this sexy semi-log graph (logarithmic scale!). Quote (with notes): Using highly compressable data (IOmeter), you get at most a 30x performance increase [for reads], and at least a 49x performance DECREASE [for writes]. Assuming I interpreted and clarified that sentence correctly, this single user's benchmark has me incredibly interested. Although write performance tanks wretchedly, read performance still soars. It gave me an idea. Idea: VirtualStore It so happens that thanks to sanity saving security features introduced in Windows Vista, write access to certain folders such as Program Files is virtualized for non-administrator processes. Which means, in normal (non-elevated) usage, a program or game's attempt to write data to its install location in Program Files (which is perhaps a poor location) is redirected to %UserProfile%\AppData\Local\VirtualStore, somewhere entirely different. Thus, to my understanding, writes to Program Files should primarily only occur when installing an application. This makes compressing it not only a huge source of space gain, but also a potential candidate for performance gain. Testing The beginning of this post has me a bit timid, it suggests benchmarking NTFS compression on a whole drive is difficult because turning it off "doesn't decompress the objects". However it seems to me the compact command is perfectly capable of doing so for both drives and individual folders. Could it be only marking them for decompression the next time the OS reads from them? I need to find the answer before I begin my own testing.

• How to update-grub on a system running overlayroot?

  - by mikepurvis

  We ship boxes configured with overlayroot, using the following overlayroot.conf: overlayroot=device:dev=/dev/sda6,timeout=20,recurse=0 Which produces the following mount configuration: $ mount overlayroot on / type overlayfs (rw,errors=remount-ro) /dev/sda5 on /media/root-ro type ext3 (ro,relatime,errors=continue,user_xattr,acl,barrier=1,data=ordered) /dev/sda6 on /media/root-rw type ext3 (rw,relatime,errors=continue,user_xattr,acl,barrier=1,data=ordered) /dev/sda1 on /boot type ext3 (rw) As you can see, three key physical partitions: sda1 is /boot, sda5 is a read-only "factory" root, and sda6 is a "user" root which can be wiped at any point to restore the machine to its original factory state. Now, the problem arises when update-grub is run for any reason: $ sudo update-grub [sudo] password for administrator: /usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?). Understandable, since / is an overlayfs. The contents of /usr/sbin/update-grub are: #!/bin/sh set -e exec grub-mkconfig -o /boot/grub/grub.cfg "$@" With /usr/sbin/grub-mkconfig being the business part of things. But the actual problem is in /usr/sbin/grub-probe, called by grub-mkconfig, and grub-probe is a binary. So my question is, is there a parameter or whatever which can make grub-probe do the right thing in the face of / being an overlayfs? And secondly, is there a way to hack/patch that in so that the update-grub script just does the right thing? Thanks.

• mysqld_safe Can't log to error log and syslog at the same time. Remove all --log-error configuration options for --syslog to take effect

• Mac OS X - User home directories shared via NFS

  - by Hugh

  I've run into some problems with how I've got user home directories set up on our system here. Our server is an XServe, using Open Directory to manage the user accounts. The majority of our workstations are OS X, but there are a few running Linux (Centos 5.3), and, as time goes on, we expect the proportion of Linux workstations to increase (at some point, we expect to move the server side over to Linux too, but for now we're running with what we've already got) To ensure that the Linux and OS X workstations both see user's home directories in the same place, I shared the home directories using NFS. On the server end, the home directories are stored in: /Volumes/data/company_users This is mounted on the workstations to: /mount/company_users This work fine on the Linux workstations, but there is some weirdness under OS X. For the user who is logged in through the GUI, it all works just fine. However, if a user tries to SSH into a machine that they are not the primary user on, they often have no access to their own home directory. It looks as though OS X is trying to do something else to the user home directories mount point when you log in through the GUI.... For example, on this machine (nv001), I (hugh) am logged into the GUI. Last login: Mon Mar 8 18:17:52 on ttys011 [nv001:~] hugh% ls -al /mount/company_users total 40 drwxrwxrwx 26 hugh wheel 840 27 Jan 19:09 . drwxr-xr-x 6 admin admin 204 19 Dec 18:36 .. drwx------+ 128 hugh staff 4308 27 Feb 23:36 hugh drwx------+ 26 matt staff 840 4 Dec 14:14 matt [nv001:~] hugh% So Matt's home directory is accessible to him. However, if I try to switch to him: [nv001:~] hugh% su - matt Password: su: no directory [nv001:~] hugh% Or: [nv001:~] hugh% su matt Password: tcsh: Permission denied tcsh: Trying to start from "/mount/company_users/matt" tcsh: Trying to start from "/" [nv001:/] matt% Does anyone have any idea why it might be doing this? It's causing me all sorts of problems at the moment... The only machine that I can successfully switch users at the moment is the server that the user directories are stored on, where /mount/company_users is actually just a symlink to /Volumes/data/company_users

• How to find out where or if MYSQL5 logs are stored on a machine WHM/Cpanel

  - by moi

  I have a WHM/Cpanel re-seller hosting account on a virtual private server (Linux). I have root access to the machine via SSH I am trying to locate a file that contains information that will help me to determine which users have accessed what db and from which hosts. I would imagine this kind of data is stored in a log file somewhere. The MySQL page says: The general query log - Established client connections and statements received from clients See: http://dev.mysql.com/doc/refman/5.0/en/server-logs.html It also says: By default, all log files are created in the mysqld data directory. So, I am am NOT asking where are the general query log logs stored, (cos I expect I will get answers saying "it depends") Please help me work out: "How can go about finding out where MySQL general query log logs are stored on a linux machine" Couple of things i've already tried: I looked at /etc/my.cnf it was a tiny file that only contained the following info: [mysqld] skip-bdb skip-innodb set-variable = max_connections=500 safe-show-database ~ ~ I have looked in: /var/lib/mysql/ But I could not see any log-like file names in that directory. Any clues on this would be most welcome.

  Can someone give me a use case for setting up a Windows Server 2008 Task Scheduler task (we'll call this "test") that completes (action completed is task=201) with an error (result code=2)? This is event trigger code for another task (called "notification" that sends out an email based on the event history of the "test" task. I've got use cases for tasks that opens a program successfully and when a program fails to find the program. I'm just trying to think of how I can test a scenario when it finds the program, but something fails with warnings or errors. /* Failed - task started but had errors (result code of 2) */ <QueryList> <Query Id="0" Path="Microsoft-Windows-TaskScheduler/Operational"> <Select Path="Microsoft-Windows-TaskScheduler/Operational"> *[ System [ Provider[@Name='Microsoft-Windows-TaskScheduler'] and (Level=0 or Level=1 or Level=2 or Level=3 or Level=4 or Level=5) and (Task = 201) ] ] and *[ EventData [ Data [ @Name='TaskName' ]='\Tasks\test' ] ] and *[ EventData [ Data [ @Name='ResultCode' ]='2' ] ] </Select> </Query> </QueryList>

• MaxStartups and MaxSessions configurations parameter for ssh connections?

  - by Webby

  I am copying the files from machineB and machineC into machineA as I am running my below shell script on machineA. If the files is not there in machineB then it should be there in machineC for sure so I will try copying the files from machineB first, if it is not there in machineB then I will try copying the same files from machineC. I am copying the files in parallel using GNU Parallel library and it is working fine. Currently I am copying 10 files in parallel. Below is my shell script which I have - #!/bin/bash export PRIMARY=/test01/primary export SECONDARY=/test02/secondary readonly FILERS_LOCATION=(machineB machineC) export FILERS_LOCATION_1=${FILERS_LOCATION[0]} export FILERS_LOCATION_2=${FILERS_LOCATION[1]} PRIMARY_PARTITION=(550 274 2 546 278) # this will have more file numbers SECONDARY_PARTITION=(1643 1103 1372 1096 1369 1568) # this will have more file numbers export dir3=/testing/snapshot/20140103 find "$PRIMARY" -mindepth 1 -delete find "$SECONDARY" -mindepth 1 -delete do_Copy() { el=$1 PRIMSEC=$2 scp david@$FILERS_LOCATION_1:$dir3/new_weekly_2014_"$el"_200003_5.data $PRIMSEC/. || scp david@$FILERS_LOCATION_2:$dir3/new_weekly_2014_"$el"_200003_5.data $PRIMSEC/. } export -f do_Copy parallel --retries 10 -j 10 do_Copy {} $PRIMARY ::: "${PRIMARY_PARTITION[@]}" & parallel --retries 10 -j 10 do_Copy {} $SECONDARY ::: "${SECONDARY_PARTITION[@]}" & wait echo "All files copied." Problem Statement:- With the above script at some point I am getting this exception - ssh_exchange_identification: Connection closed by remote host ssh_exchange_identification: Connection closed by remote host ssh_exchange_identification: Connection closed by remote host And I guess the error is typically caused by too many ssh/scp starting at the same time. That leads me to believe /etc/ssh/sshd_config:MaxStartups and MaxSessions is set too low. But my question is on which server it is pretty low? machineB and machineC or machineA? And on what machines I need to increase the number? On machineA this is what I can find - root@machineA:/home/david# grep MaxStartups /etc/ssh/sshd_config #MaxStartups 10:30:60 root@machineA:/home/david# grep MaxSessions /etc/ssh/sshd_config And on machineB and machineC this is what I can find - [root@machineB ~]$ grep MaxStartups /etc/ssh/sshd_config #MaxStartups 10 [root@machineB ~]$ grep MaxSessions /etc/ssh/sshd_config #MaxSessions 10

• rpm build from src file

  - by danielrutledge

  Hi all, I'm trying to build from a *.src.rpm file on FC 12 in such a way that the files are distributed a across my system as they would with a normal binary build (in this case, *.h files end up in /usr/include).

• How do I improve my incremental-backup performance?

  - by Alistair Bell

  I'm currently using the traditional rsync+cp -al method to create incremental/snapshot backups of our server tree. The backups are going onto a pair of eight-disk towers connected to the backup machine (a Sandy Bridge machine with 16 GB of RAM, running CentOS 5.5) via four eSATA connections (four disks per connection). Each disk is a regular 2 TB disk, so we have 32 TB of disk space connected to the backup machine. We're backing up about 20 TB of data on the servers with this. The problem is that each daily backup is taking more than 24 hours, and the real time-killer isn't the actual rsync, but the time it takes to perform a cp -al of the tree locally on the backup machine. It's taking more than 12 hours just to make the shadow copy of the tree, and as far as I can tell the performance backlog is at the disk (top shows the cp using a lot of RAM but not a lot of CPU and mostly in uninterruptible-sleep state) We have the server data split into four major volumes (and a few minor ones), and each of these backups runs in parallel (with some offsets in the cron to try to get some disks' cp done first). There are two volumes on the backup drive, both striped LVM volumes of 16 TB each. So obviously I need to improve the performance because it's unusable as it stands. The first question is: when CentOS 6 comes out, with support for btrfs, will making snapshots of subvolumes with btrfs substantially increase this performance? The second is: is there a way, with ext3 or something else supported in CentOS 5 or 6, to 'encourage' it to put the directories/inodes in one part of a volume (which could happen to be the part that's on an SSD, via LVM) and the files in another? That would presumably solve the problem, but I don't know of ways to hint ext3 like that.

• How to diagnose disk errors when disk appears to be ok?

  - by Kylotan

  I have a six-month-old 1TB Seagate drive formatted into 2 NTFS partitions, and the disk appeared to be failing with Windows dropping down from UDMA to PIO mode, reporting Delayed Write Errors, and hanging Explorer when browsing directories. My initial suspicion was that the disk was dying. However, on further examination it appears that Ubuntu, which doesn't write to the volume frequently like Windows does, was able to read the disk properly and retrieve all the data intact, saving me from having to use an older backup. Finally, running the Seatools DOS diagnostic reported that the disk has no problems, ie. SMART errors and no bad sectors, apparently. This, in combination with the relative youth of the disk, suggests that something else is broken. The cable? The PSU? The integrated disk controller? But what would be a good way to diagnose the problem without risking damaging the data? I intend to extract the disk and try it in an external eSATA enclosure and see if the write errors cease, but in the event of the disk appearing to be fine, I would like to be able to confirm what part of the hardware is actually broken here in order to know just what needs replacing. Are there any good ways to go about this?

• MySQL table does not exist

  - by Phanindra

  I am getting following error in err file. 110803 6:51:26 InnoDB: Error: table `ims`.`temp_discoveryjobdetails` already exists in InnoDB internal InnoDB: data dictionary. Have you deleted the .frm file InnoDB: and not used DROP TABLE? Have you used DROP DATABASE InnoDB: for InnoDB tables in MySQL version <= 3.23.43? InnoDB: See the Restrictions section of the InnoDB manual. InnoDB: You can drop the orphaned table inside InnoDB by InnoDB: creating an InnoDB table with the same name in another InnoDB: database and copying the .frm file to the current database. InnoDB: Then MySQL thinks the table exists, and DROP TABLE will InnoDB: succeed. InnoDB: You can look for further help from InnoDB: http://dev.mysql.com/doc/refman/5.1/en/innodb-troubleshooting.html And when I do the same, like copying the frm file from other database to here and drop the table, i am getting following error, InnoDB: Error: trying to load index PRIMARY for table ims/temp_discoveryjobdetails InnoDB: but the index tree has been freed! 110803 6:50:26 InnoDB: Error: table `ims`.`temp_discoveryjobdetails` does not exist in the InnoDB internal InnoDB: data dictionary though MySQL is trying to drop it. InnoDB: Have you copied the .frm file of the table to the InnoDB: MySQL database directory from another database? InnoDB: You can look for further help from InnoDB: http://dev.mysql.com/doc/refman/5.1/en/innodb-troubleshooting.html Please any one help me out of this. Also can any one tell me why this error is coming. EDIT: The issue is occurring only when disk size is full and when we use Truncate table. Also this is occurring only in 5.1 version but not in 5.0 version.

• IPv6: Can't ping anything - "Operation not permitted"

  - by Matthew Iselin

  I've been working on getting IPv6 support into my network, and had everything working properly for a short while. The server is running Ubuntu Server 8.10. Now however whenever I attempt to do anything related to IPv6 on the server, I get "Operation not permitted". This is coming from things like wide-dhcpv6-client (when trying to get an IPv6 address from the ISP) and radvd - both log errors of this type into syslog. Even pinging the loopback interface fails: xxx@gordon:~$ ping6 ::1 PING ::1(::1) 56 data bytes ping: sendmsg: Operation not permitted ping: sendmsg: Operation not permitted ping: sendmsg: Operation not permitted ^C --- ::1 ping statistics --- 3 packets transmitted, 0 received, 100% packet loss, time 2014ms xxx@gordon:~$ sudo ping6 ::1 sudo: unable to resolve host gordon PING ::1(::1) 56 data bytes ping: sendmsg: Operation not permitted ping: sendmsg: Operation not permitted ping: sendmsg: Operation not permitted ^C --- ::1 ping statistics --- 3 packets transmitted, 0 received, 100% packet loss, time 2014ms As you can see, I have attempted pinging as root, as most of the material I've found on the internet points to a permission problem. However, that has not helped. Any hints to getting unstuck would be appreciated.
