Most of the File systems in Linux Like ext3,ext4 support journaling in file system and thus they are less prone to corruption. But as all problems can’t always be ruled out, a Linux volume can get corrupt for many reasons. Though you can delete the corrupted volume to resolve such issues, but Linux Recovery is always a primary concern to save all data .
Here is one of the problems that a Linux generally experiences while mounting a volume. Consider you are a Linux user. You successfully shutdown your computer, but it fails to boot when you try it again it shows the below error report on the screen:
1).EXT3-fs error (device dm-0) ext3_check_descriptor: Block bitmap for
2)mount: error 2 mounting none
3)EXT3-fs group descriptors corrupted
4) mount: error 22 mounting ext3
5) group 0 not in group (block 41471)
6) switchroot: /initrd/dev failed: 2
7) Kernel panic not syncing: Attempt to kill init
This error report is preceded with the general information regarding mounting of the volume.
Reasons
The Above errors most likely occur because of journal file corruption in ext3 File system logical volume.
Ext3 is a journaled file system that keeps record of all the changes in a journal file. This file is helpful in bringing the file system back to its original state after any system crash. Damage to journal file can cause serious Problems
Solution
In order to resolve the discussed issue, you should follow the below mentioned steps:
• Boot the system with the help of system Rescue CD
• After booting the System, you can run fsck.ext3 command to repair the corrupted ext3 volume
However, if the problem persists, the only solution is to recreate the volume and restore lost data from the recent backup.
There are situations when data backup is not in usable state. To deal with such issues, you can use Ext3 Recovery software. These are perfect Linux Recovery tools designed to scan a corrupted or deleted Linux volume and extract possible data to a safer location.
