Linux Recovery Solution To Deal With File System Corruption Issues

In the Linux system, the 'mount' command is used to enable the partitions

. Moreover, with the 'mount' command, the Linux OS is triggered to avail the data and information of the particular partition to be accessed. However, sometimes, the command fails to mount the partition and following which, all the data in that particular drive becomes completely inaccessible. The cause may be a possible corruption to the file system of the Linux system and you can use any Linux recovery software to recover back the data.

Sensing a file system based error, if you run the 'fsck' utility to mount, you may come across the below error messages:

"fsck.ext2: Bad magic number in super-block while trying to open /dev/mapper/mpath0p1

/dev/mapper/mpath0p1:


The superblock could not be read or does not describe a correct ext2

file system. If the device is valid and it really contains an ext2

file system (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 "

OR

"[/dev/mapper]fsck -a /dev/mapper/mpath0p1

fsck 1.35 (28-Feb-2004)

ext2fs_check_if_mount: Input/output error while determining whether /dev/mapper/mpath0p1 is mounted."

The above error messages can clearly indicate towards a possible file system corruption issue and you can run the 'fsck' utility itself to fix the errors.

'fsck' is an inbuilt utility in Linux to check the file system based errors and at many times fixes the same. However, with severe corruption, 'fsck' simply exits without doing anything. In such a case, you have to format the hard drive and make fresh partitions. After that, restore the data from the backup. In case, you do not possess a valid backup, you can always use a Linux data recovery utility to retrieve the lost data safely.

These data recovery Linux software are extremely powerful and can recover all your lost, deleted or even formatted data from any instance of data loss from your Linux OS based drives. Moreover, with friendly interfaces, the software can be easily used without needing any expertise.
