Most of the Linux file systems, including ext3, support file system journaling and thus are less prone to corruption. But as all problems can’t always be ruled out, a Linux volume can get corrupt for multitude of reasons. Though you can delete the corrupted volume and resolve such issues, but Linux Data Recovery is always a primary concern for all data preserving users.

Here is one of the problems that a Linux user can experience when mounting a volume. Consider you are a Linux user. You successfully shutdown your computer, but the next time when you try to boot the computer, it doesn’t boot and shows the below error report on the screen:

.EXT3-fs error (device dm-0) ext3_check_descriptor: Block bitmap for

group 0 not in group (block 41471)

EXT3-fs group descriptors corrupted

mount: error 22 mounting ext3

mount: error 2 mounting none

switchroot: /initrd/dev failed: 2

Kernel panic not syncing: Attempt to kill init

This error report is preceded with the general information of mounting the volume.


The aforementioned error most likely occurs because of journal file corruption in ext3 logical volume.

Ext3 is a journaled file system that keeps a record of all the changes in a file called journal file. This file is helpful in bringing the file system back to its original state post any power failure or system crash. Damage to journal file can cause serious consequences, such as above.


In order to resolve the discussed issue, you should follow the below mentioned steps:

•    Since the computer is unable to boot, you should get a System Rescue CD to boot the computer

•    After booting the computer, 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 last available backup.

There are situations when data backup is found as corrupted or incomplete for some reasons. To deal with such problems, you can use Ext3 Recovery software. These are perfect Linux Data Recovery tools designed to scan a corrupted or deleted Linux volume and extract possible data to a safe location.
