- During boot filesystem fails to mount with error
The superblock could not be read or does not describe a correct filesystem. If the device is valid and it realy contains an ext2 filesystem (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 <device> ... *** An error occurred during the file system check. *** Dropping you to a shell; the system will reboot *** when you leave the shell. Give root password for maintenance (or type Control-D to continue):
- From maintenance mode vgchange -ay [VolumeGroup] followed by fsck [device] fixes the issue until the next reboot.
