How to mount Linux in case the superblock is corrupted

In Linux system, memeory blocks are used to store all kinds of data. One of them is metadata. One of the most important metadata is superblock its main function is to keep all the details about the file system such asits block size. Hence, the superblock is one of the most components of the Linux system.However, it happens that your access to the superblock is blocked, resulting into disabling of mounting of the file system.

Consider a scenario when you fails to mount your ext3-based Linux system. the below message is displayed

"/dev/sda2: Input/output error
mount: /dev/sda2: fails to read superblock"

Reason:

The main reason behind this error is that the system files are damaged. Because of this, you fails to mount system files.

Solution:

To resolve this issue, you should restore the primary superblock from the updated backup copies.

The following procedures need to be followed in this case:

    A)  Locate the superblock for the /dev/sda2 location.

    B)  Repair the file system using alternate superblock #abc

where, abc is the location of the new superblock.

  C) Mount the System file using the following mount command:

# mount /dev/sda2 /mnt

    D) Finaly try to browse the file system and check if you are able to view all the files or not.

However, if you still fails to mount the file system then the only option available with you is to use a third-party Linux recovery software to recover the inaccessible data.
