Hi Pacemaker Experts I have inherited a pacemaker cluster running on the SLES11SP1 stack. Sadly there is no support contract any more.
# rpm -qa | egrep 'pacemaker' pacemaker-mgmt-2.0.0-0.5.5 pacemaker-mgmt-client-2.0.0-0.5.5 pacemaker-1.1.5-5.9.11.1 libpacemaker3-1.1.5-5.9.11.1 drbd-pacemaker-8.3.11-0.3.1 I need to migrate both SBD devices. I.e. /dev/sdX and /dev/sdY. to /dev/sdA and /dev/sdB It is required to do this without service downtime. The sbd resource is running OK: # crm_mon -1 | grep sbd stonith_sbd_is (stonith:external/sbd): Started node1 and is configured as follows # crm configure show | grep sbd primitive stonith_sbd_is stonith:external/sbd \ params sbd_device="/dev/sdX;/dev/sdY" and sbd processes are running from this config # cat /etc/sysconfig/sbd SBD_DEVICE="/dev/sdX;/dev/sdY" SBD_OPTS="-W" pstree -halp | grep sbd |-sbd,8797 | |-sbd,8798 | `-sbd,8799 (similarly on node2) The resources are all running, and both nodes are OK # crm_mon Last updated: Thu Jan 29 18:52:53 2015 Stack: openais Current DC: s987l1020 - partition with quorum Version: 1.1.5-5bd2b9154d7d9f86d7f56fe0a74072a5a6590c60 2 Nodes configured, 2 expected votes 61 Resources configured. ============ Online: [ node1 node2] stonith_sbd_is (stonith:external/sbd): Started node1 .... Is this change possible without stopping the cluster? If so, how should I best implement? With downtime I guess all I would need to do is change the /etc/sysconfig/sbd file, change the settings within the cluster via crm, and restart everything. But I cannot see the cluster surviving this without a downtime?
