| Corruption found in superblock. (reserved_gdt_blocks = 15679). |
| |
| The superblock could not be read or does not describe a correct ext2 |
| filesystem. If the device is valid and it really 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: |
