hello all
recently i've faced xfs crash on my md RAID5 (ap. 700GB). strange thing is
that RAID5 did not have any problems (no device have faled, no resync
needed).
when i am trying to mount filesystem:
XFS: totally zeroed log
XFS: failed to read root inode
mars root # xfs_repair -v /dev/md1
Phase 1 - find and verify superblock...
couldn't verify primary superblock - not enough secondary superblocks with
matchinggeometry !!!
attempting to find secondary superblock...
......................................................
and so on and on..... and at the end claims that he could not verify
superblock.
however
mars root # xfs_db /dev/md1
xfs_db: cannot read root inode (22)
xfs_db: cannot read realtime bitmap inode (22)
xfs_db> sb

values seems to be valid. my question: is there any chance to get back my
data from that filesystem ?
