<div dir="ltr"><div><div><div><div><div><div><div><div><div>Hi all,<br><br></div>I'm trying to configure DRBD+Pacemaker+XEN+OCFS2 for ACTIVE/ACTIVE VM failover.<br><br></div>I'm stuck at the first step itself, installing and configuring Pacemaker to handle DRBD.<br>
<br></div>There are 2 issues I'm facing :<br></div>1. After installing DRBD using "apt-get install drbd8-utils", the /dev/drbd/by-res/r0 or /dev/drbd/by-disk/disk_name folders are not created by itself (Few months back I had followed same procedure to install DRBD, it created the folders mentioned above)<br>
</div>As this /dev/drbd/by-res/r0 used for configuring Pacemaker, putting this query<br><br></div>2. Although the above mentioned folders are not created, running DRBD manually works fine.<br></div>When integrated with pacemaker to handle DRBD, DRBD doesn't start at all.<br>
</div>Find the attached logs for DRBD and Pacemaker configuration used and the logs from 2 servers<br><br></div><div>Request :<br></div><div>Can anyone please suggest best UBUNTU( or any other OS suggestion also fine), DRBD and Pacemaker versions which works fine to be used in production level<br>
<br></div>Looking for a solution as same is to be deployed in Production Servers :(<br><br><div><div><div><div><div><div><div><div><div><div><div>-- <br>Regards,<br>Kamal Kishore B V<br>
