Repairing a Corrupted Superblock
- Locate the superblock alternates of the filesystem

- Choose a superblock alternate location, and check the filesystem using fsck
- # e2fsck -b <alternate location> /dev/<device>
- Attempt to mount the filesystem
Mounting a Filesystem with a Corrupted Superblock
- Locate the superblock alternates of the filesystem
- # dump2fs /dev/<device> | grep -i superblock
- The filesystem can also be mounted by passing the location of an alternate superblock to the mount command
- # mount sb=<alternate location> /dev/<device> <mount location>
