NOTE: The XFS file system doesn't seem to support quotas.

Setup for a partition mounted at /:

* <code>touch /aquota.user</code>
* <code>chmod 600 /aquota.user</code>
* edit <code>/etc/fstab</code>, add "<code>,usrquota</code>" after the word "<code>defaults</code>" in the affected partition.
* reboot
* <code>quotacheck -vm /</code>
* <code>quotaon -v /</code>

To setup quotas for a certain user:
<pre>
setquota <user> <soft-limit> <hard-limit> 0 0 <mount-point>
</pre>

Example: to set a soft-limit of 10MB, hard-limit of 12MB, for sccmarti whose home directory /home/sccmarti lives under the / mount point:
<pre>
setquota sccmarti 10240 12288 0 0 /
</pre>

To edit quotas (using editor specified in $EDITOR, or vi):
<pre>
edquota <user>
</pre>

To view quotas for a specific user:
<pre>
quota <user>
</pre>

To update quota files
<pre>
quotacheck -vfm /
</pre>

To see a report on quota usage
<pre>
repquota -a
</pre>

==Troubleshooting==
If <code>repquota</code> shows much more used space than you can account for, check <code>/root/.cpan/build</code> for perl modules that don't belong to root.
