<div>The xfs partition for <i>server02:/brick1</i> has been

second server to the volume with an empty brick and the
data will auto replicate over from the working server?</div>

<font size="2"><font face="Arial">Yes this should work fine. You
will need to run a `gluster volume heal myvol full` to manually
trigger the replication.</font></font><br>
