Hi Steve, I have not answered before because I was on holidays. By the
way, happy new year.
I have looked /proc/mounts as you told me, and ... surprise:
/dev/mapper/volCluster-lvol0 /mnt/gfs gfs
rw,hostdata=jid=0:id=196610:first=1,localflocks 0 0
"localflocks" is there! I don't understand because I mount it using
"/etc/init.d/gfs start" which looks at /etc/fstab, and there the line is:
/dev/volCluster/lvol0 /mnt/gfs gfs defaults 0 0
I must admit that there is a particular thing in this system which I
thought it didn't affect, but I am not so sure now, and that is it is a
OpenVZ patched kernel. Can this have something to do with gfs mounts?
Thanks for your help once more.
Frank

I don't know. What does it say in /proc/mounts? (or what was your mount
command line?)
