[Lustre-discuss] Lustre 1.6.6 - cannot get rid of user_xattr on Sles10

[Andrei Maslennikov]

On an only RHEL 4.7 OSS/MDT machine used in some standalone setup we have:

# mount
/dev/sdc8 on /lusys/mgt type lustre (rw,noacl,nouser_xattr)
<--- MDT
/dev/lustre/united on /lusys/ost1 type lustre (rw,noacl,nouser_xattr)
<--- OST
20.20.20.1 at o2ib:/lustre on /lustre type lustre
(rw,noacl,nouser_xattr)    <--- Client

On this machine I can create files inside Lustre(/lustre) and then move them

to any other local file system withut any problem.

Instead, on a Suse SLES10SP2 client machine with unmodified kernel we got:

# mount
20.20.20.1 at o2ib:/lustre on /lustre type lustre (rw,noacl,nouser_xattr)

However, any attempt to move any file from inside /xenfs to, say, /tmp
ends up correctly (file is being moved), but insists on the following error:

# mv /lustre/uuu /tmp
mv: setting attributes for `/tmp/uuu': Operation not supported
Could someone advice us on how to get rid of this? Not so long ago somebody
had a similar issue, but the problem apparently remained unsolved. There
should
be some setting overlooked by us on Suse only (on Red Hat it works)... but
what may this be?...

Andrei.

PS tunefs.lustre accepts the persistent setting of nouser_xattr, but puts it
*after*
user_xattr:

Persistent mount opts:
errors=remount-ro,iopen_nopriv,user_xattr,nouser_xattr

This however does not change anything as we mount /lustre with nouser_xattr
options on the common line. The issue is still there...
