Yay! It happened again!
[397113.459309] EXT4-fs error (device md0): ext4_iget:3821: inode #100691970: comm updatedb.mlocat: checksum invalid
[397113.459315] Aborting journal on device md0-8.
[397113.496222] EXT4-fs (md0): Remounting filesystem read-only
However, trying to preserve the evidence runs into a problem:
/root# e2image -Q /dev/md0 md0.qcow2
e2image 1.43-WIP (1-Aug-2012)
e2image: Inode checksum does not match inode while getting next inode
/root# ls -l md0.qcow2
-rw------- 1 root root 0 Aug 8 18:30 md0.qcow2
e2image aborts on the checksum error, preventing me from capturing a useful
image.
Can someone find a workaround QUICKLY? I can't keep this FS read-only
for long.
Thanks!
