Hi,
I had a (software) problem with my xen server ended ruining my domU
partitions. I already recovered all my ext4 partitions using fsck.ext4,
but I can't recover the only xfs partition I have :(
When I try to mount I get:
root@firewall:~# mount -o loop,offset=$((97280*1024)) -t xfs
/srv/xen/webserver.img /mnt
mount: Structure needs cleaning
While when trying to fsck I get:
root@firewall:~# xfs_check /dev/loop51
xfs_check: /dev/loop51 is not a valid XFS filesystem (unexpected SB
magic number 0xeb639010)
xfs_check: size check failed

Phase 1 - find and verify superblock...
bad primary superblock - bad magic number !!!
attempting to find secondary superblock...
................................................................................found
candidate secondary superblock...
unable to verify superblock, continuing...

[...]
....................................Sorry, could not find valid
secondary superblock
Exiting now.
How can I restore my data? I cannot believe I had no problems restoring
*15* ext4 partitions while I can't restore the only xfs partition I have :(
Hope you can help,
Niccolò
