Segmentation fault in xfs_db frag, xfsprogs-3.1.8

[Richard Ems]

Hi list,

I have a cron script running all weekends reporting me the fragmentation
of one of our backup systems.
It ran fine up to last weekend when it started reporting "Segmentation
fault".

This is on an openSUSE 12.1 64bit, running kernel 3.3.6.

I tried with xfsprogs3.1.6 and the self compiled 3.1.8 version. Both end
with segmentation fault.

# df -h /dev/sdc
Filesystem      Size  Used Avail Use% Mounted on
/dev/sdc         80T   57T   23T  72% /backup/ES-6664

# mount | grep sdc
/dev/sdc on /backup/ES-6664 type xfs
(rw,noatime,attr2,nobarrier,inode64,logbufs=8,logbsize=256k,sunit=128,swidth=3712,noquota,_netdev)
/dev/sdc on /backup/ES-6664 type xfs
(ro,relatime,attr2,nobarrier,inode64,logbufs=8,logbsize=256k,sunit=128,swidth=3712,noquota,_netdev)

The FS gets first mounted rw and then bind mounted ro on top of it.

# xfs_info /dev/sdc

# echo frag | xfs_db -r /dev/sdc
Segmentation fault

# echo frag | /opt/xfsprogs-3.1.8/sbin/xfs_db -r /dev/sdc
Segmentation fault


Any clues?

Thanks,
Richard
