../e2fsck/e2fsck: Filesystem has unsupported feature(s) while trying to open test.img
|
|
|
|
The superblock could not be read or does not describe a valid ext2/ext3/ext4
|
|
filesystem. If the device is valid and it really contains an ext2/ext3/ext4
|
|
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>
|
|
or
|
|
e2fsck -b 32768 <device>
|
|
|
|
Exit status is 8
