So, you use the lovely XFS file system, but those meanies at linux-vserver have told you it's not supported. :) No problems.
To get the same sort of effect as dlimits, while using the XFS file system, you can use Project Quotas.
Let's say we want to limit /vserver/foo to 5G of space.
Edit /etc/fstab, and put prjquota as an option for /vserver, and reboot. (I don't think -o remount works). It should look like this:
# grep prjquota /etc/fstab /dev/cciss/c0d0p7 /vserver xfs noatime,prjquota 0 0
Warning: XFS: cannot mount with both project and group quota
echo "1235:/vservers/foo" >> /etc/projects(I use the context for the project ID number)
echo "foo:1235" >> /etc/projid(This is just so you can refer to a project by name)
Now we just set up the quota....
xfs_quota -x -c 'project -s foo' /vserver
And set our limits on it. (bhard = blocks hard, bsoft = blocks soft)
xfs_quota -x -c 'limit -p bsoft=4800M bhard=5G foo' /vserver
Voila. Vservers with XFS.
You can check the usage, etc with:
# xfs_quota -x -c 'report' /vserver
Project quota on /vserver (/dev/cciss/c0d0p7)
Blocks
Project ID Used Soft Hard Warn/Grace
---------- --------------------------------------------------
foo 10002856 4915200 5242880 00 [--none--]
....
It does work, but df -h doesn't show the limit properly in the vserver. It does show the size, and the used, but the avail it still takes from the
# df -h Filesystem Size Used Avail Use% Mounted on /dev/hdv1 5.0G 3.0G 17G 21% /
