Hi!
I had a XFS filesystem on RAID 5, but line of the power supply 230 V had
crash . UPS failed, 2 hard disk drive on RAID (4 hard disk) failed
(medium error) - then before turn of computer I resynchronize this
RAID. Fdisk recognized filesystem as XFS. Using dd with conv=noerror,
sync I clone XFS filesystem on external hard disk. After restart machine
I never can resynchronize RAID to see XFS filesystem. Then I connect
hard disk to computer I can mount , but I see numbers as filename with
extensions.

xfs_repair :
couldn't verify primary superblock not enough secondary superblocks with
matching geometry
attempting to find secondary superblock......................
xfs_check said
cannot init perag data (117).
I use xfs_explorer, UFS Explorer Professional Recovery, photorec,
testdisk to recover files, but any of this nothing do.
It's very important because on filesystem XFS there was a virtual
machine file with many MS SQL databases. I can't have backup because
packed backup file has a 17 GB, external hard disk destroyed after the
supertension of the energy network.
Please help me...
