<p class="MsoNormal">That's easily accomplished with Pacemaker cluster manager,<br>
there are many guides on how to do it all over the internet.<br>
<br>
Simply said, Pacemaker controls both DRBD and ISCSI targets<br>
and if the slave node detects master's failure - it promotes<br>
DRBD to primary, brings up shared ip address and starts ISCSI.<br>
<br>
But your problem can be, i think, solved much simpler:<br>
you just need to rsync your ISO's to another server, because,<br>
as i see it, they are changed infrequently. Then you can use cluster<br>
manager to fail over IP address between these servers.<br>
