Hi all !
We have a XFS that started giving errors some days ago.
This is on an openSUSE 11.4 64 bit system.
The XFS is 12 TB big, 9.8 TB are used. Hardware RAID 6 on an Areca 1680
controller.
Mounting the XFS with ro,norecovery works almost always.
But xfs_repair crashes with a Segmentation fault. I tried both v3.1.4 from
openSUSE 11.4 and xfs_repair v3.1.6 downloaded from the git repo.
Now after a reboot - the ___production___system completely freezed while
running
the last xfs_repair v3.1.6 !!! - the XFS got mounted rw, but just trying to
touch a file generated the following error:

The complete " xfs_repair -n -P /dev/sdb1 " output file is 1.2 MB gzipped. If
anyone wants
to have a look at it please ask and I will send it as a private mail.
What can I do to recover/repair this XFS ? We have important data in there !
Many thanks,
Richard
