Hi Helmut, first of all, thanks for your reply!<div><br></div><div>I was looking for how to work with <span style="color:rgb(34,34,34);font-family:arial,sans-serif;font-size:13px;background-color:rgb(255,255,255)">ocf:heartbeat:Xen tag on pacemaker. Let me ask some questions.</span></div>
<div><font color="#222222" face="arial, sans-serif"><br></font></div><div><font color="#222222" face="arial, sans-serif">1 - It is possible to add </font><span style="color:rgb(34,34,34);font-family:arial,sans-serif;font-size:13px;background-color:rgb(255,255,255)">ocf:heartbeat:Xen to may configuration and keep using LVM on DRBD?</span></div>
<div><font color="#222222" face="arial, sans-serif"><br></font></div><div><font color="#222222" face="arial, sans-serif">2 - I never worked with RAID. Should I modificate my configuration at some points for this or can I remain with out RAID?</font></div>
<div><font color="#222222" face="arial, sans-serif"><br></font></div><div><font color="#222222" face="arial, sans-serif">3 - You put </font><span style="color:rgb(34,34,34);font-family:arial,sans-serif;font-size:13px;background-color:rgb(255,255,255)">/etc/xen/mail4.cfg file on etc/xen directory. What is gonna happen with the primary became out of the network and the secondary will look for cfg file to restore the VM?</span></div>
<div><font color="#222222" face="arial, sans-serif">Let me explain how I am doing it. At my configuration, a Java program on secondary machine is looking for prinmary machine. If the primary fall down, the Java program change DRBD to primary, mount the /dev/drbd7 and restore a chekpoint that is there. I have to put the files of Xen on the DRBD partition (.img, .iso, .chekpoint, .cfg).</font></div>

<div>Talking about stonith/fencing I was working with Corosync+Pacemaker+Xen+DRBD but the pace maker configurations got failed when I put all components together. I mean, when I was with Corosync+Pacemaker+DRBD the fencing worked well! After I put Xen together the pacemaker configuration got failed.</div>
