i'm also interested in this. is there any pro/con to using native gluster FUSE client for xen images? i would have thought that would mitigate the use of ucarp (apart from initial connect).<div><br></div><div>-p</div>

</div>Pretty much the standard thing to do is use a virtual IP address with ucarp<br>
handling reassignment if the primary node goes down. I've yet to run that<br>
through thorough tests to see if how transparent it is in a case of failure.<br>
It's simple to set up though.<br>
<br>
There are, of course, plenty of more complicated alternatives to ucarp in<br>
the HA world - heartbeat, pacemaker, corosync....<br>
