<html><head><style type='text/css'>p { margin: 0; }</style></head><body><div style='font-family: Times New Roman; font-size: 12pt; color: #000000'>Hello,<br><br>I have a 3 node Pacemaker + Corosync cluster with 2 "real" nodes, node0 and node1, running a DRBD resource (single-primary) and the 3rd node in standby acting as a quorum node. If node0 were running the DRBD resource, and thus is DRBD primary, and its power supply fails, will the DRBD resource be promoted to primary on node1?<br><br>If I simply cut the DRBD replication link, node1 reports the following state:<br>Role:<br>Secondary/Unknown<br><br>Disk State:<br>UpToDate/DUnknown<br><br>Connection State:<br>WFConnection<br><br><br>I cannot manually promote the DRBD resource because the peer is not outdated:<br>0: State change failed: (-7) Refusing to be Primary while peer is not outdated<br>Command 'drbdsetup 0 primary' terminated with exit code 11<br><br>I have configured the CIB-based crm-fence-peer.sh utility in my drbd.conf<br>fence-peer "/usr/lib/drbd/crm-fence-peer.sh";<br>but I do not believe it would be applicable in this scenario.<br><br>If node0 goes offline like this and doesn't come back (e.g. after a STONITH), does Pacemaker have a way to tell node1 that its peer is outdated and to proceed with promoting the resource to primary?<br><br>Thanks,<br><br>Andrew<br></div></body></html>
