<div class="moz-cite-prefix">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>

<p class="MsoNormal"><span style="color:#1F497D">Can I take 2
servers, setup DRBD between them, then configure ISCSI on
both servers but only connect to 1 of the ISCSI targets.
Leave the other ISCSI service turned off until needed. I
would create a VIP between the two servers so that the
clients wouldn’t need to be reconfigured to point to the new
active ISCSI. I am looking for a fail over file system
which will hold my ISO an boot images for my PXE
environment.<o:p></o:p></span></p>

configured to listen to a backend network using a small 1gig
