I've found that the performance for such a small setup is terrible, the maintenance headache is high and when a drive drops out, the performance gets *really* bad. Last time I checked, gluster was much slower at healing large files than ceph, I'm hoping that has improved :)<br></div><div><br>-- <br><div class="gmail_signature">Lindsay</div>
