RHEL6: Getting 'filesystem revision too high' when using various ext4 filesystem tools
Issue
- Attempting to resize a filesystem fails with 'Filesystem revision too high':
# resize2fs /dev/somevg/somelv
resize2fs 1.41.12 (17-May-2010)
resize2fs: Filesystem revision too high while trying to open /dev/somevg/somelv
Couldn't find valid filesystem superblock.
- Attempting to perform a check (fsck) on a filesystem fails with 'filesystem revision is apparently too high'.
# fsck -f /dev/somevg/somelv
fsck from util-linux-ng 2.17.2
e2fsck 1.41.12 (17-May-2010)
fsck.ext4: Filesystem revision too high while trying to open /dev/mapper/somevg-somelv
The filesystem revision is apparently too high for this version of e2fsck.
(Or the filesystem superblock is corrupt)
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:
e2fsck -b 8193 <device>
# e2fsck -b 8193 /dev/somevg/somelv
e2fsck 1.41.12 (17-May-2010)
e2fsck: Bad magic number in super-block while trying to open /dev/somevg/somelv
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:
e2fsck -b 8193 <device>
- Cannot determine filesystem information with dumpe2fs, as it also returns 'Filesystem revision too high'
# dumpe2fs /dev/somevg/somelv
dumpe2fs 1.41.12 (17-May-2010)
dumpe2fs: Filesystem revision too high while trying to open /dev/somevg/somelv
Couldn't find valid filesystem superblock.
- The filesystem can be mounted, however errors similar to the following may appear in system logs:
Apr 12 15:53:23 localhost kernel: EXT4-fs (dm-1): revision level too high, forcing read-only mode
Apr 12 15:53:23 localhost kernel: EXT4-fs (dm-1): mounted filesystem with ordered data mode. Opts:
