Thread-topic: bad version from xfs_repair after raid crash
> Is your xfsprogs version up to date?


I guess the xfsprogs are rather old but they should be on the same level as the 
filesystem as they are part oft he same distro (OpenFiler 2.3, package is 
called xfsprogs=2.6.25-4-0.1).

Here ist he output of xfs_db:

magicnum = 0x58465342
blocksize = 4096
dblocks = 332800000
rblocks = 0
rextents = 0
uuid = 567f4c2f-ce9a-42a3-bbc2-e791cf43f8ae
logstart = 268435460
rootino = 128
rbmino = 129
rsumino = 130
rextsize = 1
agblocks = 83200000
agcount = 4
rbmblocks = 0
logblocks = 32768
versionnum = 0xb4a4
sectsize = 512
inodesize = 256
inopblock = 16
fname = "\000\000\000\000\000\000\000\000\000\000\000\000"
blocklog = 12
sectlog = 9
inodelog = 8
inopblog = 4
agblklog = 27
rextslog = 0
inprogress = 0
imax_pct = 5
icount = 1079360
ifree = 80
fdblocks = 178779506
frextents = 0
uquotino = 131
gquotino = 132
qflags = 0x77
flags = 0
shared_vn = 0
inoalignmt = 2
unit = 0
width = 0
dirblklog = 0
logsectlog = 0
logsectsize = 0
logsunit = 1
features2 = 0x8

But I have already experimented a little bit, originally versionnum was 0xb4f4 
but the next superblock (sb 1) contained 0xb4a4, so I tried to set it with 
xfs_db to this value, but it didn't make a difference.
