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: Oct 17 16:33:02 c3m kernel: [ 794.628715] Filesystem "sdb1": XFS internal error xfs_btree_check_sblock at line 120 of file /usr/src/packages/BUILD/kernel-default-2.6.37.6/linux-2.6.37/fs/xfs/xfs_btree.c.

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 !
