<p class="MsoNormal"><span style="color:#1F497D">Will try both options. Ideally trying to get all info from the backend side but it may not be possible. Some info (e.g. space, quotas etc.) are only available via ‘lfs’ looks like so a client has to be involved.
I guess with multiple filesystems, I just need to have one client that has them all always accessible.<o:p></o:p></span></p>
