Hi list,
I have a serious problem with a 60 TB XFS filesystem which looks
seriously hosed. It was repaired once earlier last week, but crashed
again after a repair friday and now xfs_repair fails with this message:
bad magic # 0x1 in btcnt block 61/27137
bad magic # 0xfffe68ff in btcnt block 61/201728942
(xfs_repair 2.9.8)
The filesystem can only be mounted read-only at this point.
I suspect a RAID corruption (Adaptec 52445 with firmware 18252, Hitachi
HUA 3TB drives, RAID 6). The RAID controller have been replaced, but it
doesn't help. Any ideas?

Can you update the xfs tools to the current (3.1.8 I think)? Also,
which kernel is being used?

We'll try running a recent enough version of xfs_repair tomorrow. The
kernel is 3.2.21 at the moment. The xfs filesystem looks like this:
xfs_info /dev/dm-0
meta-data=/dev/mapper/vg0-raid isize=256 agcount=71,
agsize=268435440 blks = sectsz=512 attr=2
data = bsize=4096 blocks=19013298176,
imaxpct=1 = sunit=16 swidth=32 blks
naming =version 2 bsize=4096
log =internal bsize=4096 blocks=32768, version=2
= sectsz=512 sunit=16 blks,
lazy-count=1 realtime =none extsz=131072 blocks=0,
rtextents=0

I hadn't the latest version at hand, but we tried with a 3.1.4 version
and it failed in exactly the same manner. I tend to suspect an
incomptibility between the 3 TB drives and the RAID controller, but I
can't be sure. Did anyone heard of any such problem?
Apparently only the XFS filesystem fails; another (reiserfs) filesystem
on another partition on the same RAID array didn't suffer from any
problem.
