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?
