Repairing a Corrupted Superblock
- Locate the superblock alternates of the filesystem.
- # dump2fs /dev/<device> | grep -i superblock
- Choose a superblock alternate location, and check the filesystem using fsck.
- # fsck -b <alternate location> /dev/<device>
- Attempt to mount the filesystem.
Mounting a FS 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>
