Hey guys,
I am trying to recover 8Tb after a raid failure. RAID issues seem to
be resolved, but cannot mount the fs,
dmesg says:
EXT4-fs (md127): bad geometry: block count 1953512448 exceeds size of
device (1953509376 blocks)
OS sees ext4
have complete dd back of fs, so I can kick it around
debugfs cannot see fs structure.
fsck tried to fix every inode, but at 500M inodes (and would take a
month to complete), that far exceeds used inodes
Am I beating a dead horse here, or is there some hope for recovery?
Thanks in advance,
Paul

Are you sure the md device is set up properly? It seems to be 3072
shorter than the fs...

What does that mean?

Off the top of my head, I think maybe your raid is not as happy as you
hope it is...
