Subject: Ext4 Filesystem recovery ...

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
