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_db -c "sb 0" -c "p" /dev/sde5 said: magicnum = 0x58465342 blocksize = 4096 dblocks = 183103920 rblocks = 0 rextents = 0 uuid = e2716dab-5b52-085e-eae2-3d8442c32a1a logstart = 134217735 rootino = 256 rbmino = 257 rsumino = 258 rextsize = 1 agblocks = 5722000 agcount = 32 rbmblocks = 0 logblocks = 89406 versionnum = 0xbdb4 sectsize = 4096 inodesize = 256 inopblock = 16 fname = "\000\000\000\000\000\000\000\000\000\000\000\000" blocklog = 12 sectlog = 12 inodelog = 8 inopblog = 4 agblklog = 23 rextslog = 0 inprogress = 0 imax_pct = 25 icount = 37056 ifree = 7341 fdblocks = 181668411 frextents = 0 uquotino = 0 gquotino = 0 qflags = 0 flags = 0 shared_vn = 0 inoalignmt = 2 unit = 16 width = 48 dirblklog = 0 logsectlog = 12 logsectsize = 4096 logsunit = 4096 features2 = 0xa bad_features2 = 0xa 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.
