I have trouble setting up project quotas on SLES11 SP2: Simply following
the example in the man page

# mount -o remount,defaults,prjquota /var
# echo 42:/var/log >> /etc/projects
# echo logfiles:42 >> /etc/projid
# xfs_quota -x -c 'project -s logfiles' /var
# xfs_quota -x -c 'limit -p bhard=1g logfiles' /var

I get the following error after the last command:
xfs_quota: cannot set limits: Function not implemented

# mount | grep var
/dev/mapper/vg1-var on /var type xfs (rw,prjquota)

I xfs_quota on SUSE broken? Has anybody used project quota on xfs with
success on SUSE?
