So we put another drive with a working OS and from there we try to mount the partitions in the old drive. Most partitions mount fine except for one: the /var partition, where my MySQL tables reside. http://serverfault.com/questions/493091/how-to-recover-data-from-a-corrupted-ext3-partition When I try to mount that one, I see these errors with dmesg: sd 0:0:1:0: Unhandled sense code sd 0:0:1:0: SCSI error: return code = 0x08100002 Result: hostbyte=invalid driverbyte=DRIVER_SENSE,SUGGEST_OK sdb: Current: sense key: Medium Error Add.

won't boot, all your filesystem checks tell you you've a bad superblock, but you cant seem to find how to fix it. Well, here goes🙂 This guide is for ext4 , though I'll explain how https://linuxexpresso.wordpress.com/2010/03/31/repair-a-broken-ext4-superblock-in-ubuntu/ other filesystems can be cured along the way. The easiest way to carry all http://linux.bigresource.com/CentOS-5-EXT3-fs-unable-to-read-superblock-enable-this--jAdymDvkC.html this out, seeing as your computer probably won't boot at this stage, is to download and burn a copy of Parted Magic. Boot from that, and you'll access to a number of useful tools. First, figure out what partition we're dealing with. sudo fdisk -l The above will list all the partitions on all the drives in fs error your computer. To recover a lost partition, your going to need Testdisk. Testdisk is included in Parted Magic, and there's a great guide on their site. For this though, we just need the partition number, such as /dev/sda3 or /dev/hdb1. Now, make sure your superblock is the problem, by starting a filesystem check, replacing xxx with your partition name. Here, you can change ext4 to ext3, or ext2 to suit the filesystem. ext3-fs error (device sudo fsck.ext4 -v /dev/xxx If your superblock is corrupt, the output will look like this fsck /dev/sda5 fsck 1.41.4 (27-Jan-2009) e2fsck 1.41.4 (27-Jan-2009) fsck.ext4: Group descriptors look bad... trying backup blocks... fsck.ext4: Bad magic number in super-block while trying to open /dev/sda5 The superblock could not be read or does not describe a correct ext4 filesystem. If the device is valid and it really contains an ext4 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock: e2fsck -b 8193
kill init!". Here are the details: I have a brand new Dell PowerEdge T110 server with Quad-Core Xeon CPU and 2GB 1333MHz RAM. I have installed a hard disk (SATA, 7.2rpm) on this machine that I removed from another Dell PowerEdge T100 server with Dual-Core Xeon CPU that was running software RAID 1. Now when I boot the new T110 server, it displays the following error messages code... I am running CentOs v5.5 x86-64. If I put the hard disk back into T100, it boots fine. I do not know why it is not working with T110 server.
