<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Verdana","sans-serif"'>Problem:<br>
<br>
The problem is that when performing an HA failover from server A to server
B,&nbsp;&nbsp;a DRBD resource is sometimes not shut down properly on server A.
Several attempts are made to stop the DRBD resource, but finally it gives up
and the server is rebooted. The failover to server B works properly; B becomes
the Active server. After the reboot, server A comes up properly as the Standby
server.<br>
<br>
The problem is intermittent. Most HA failovers work as expected (server A does
not reboot).<br>
<br>
When the problem does occur, the following lines are logged in
/var/log/messages and displayed on the OOBM:<br>
<br>
drbd0: State change failed: Device is held open by someone<br>
