systemd: Dependency failed for Pacemaker High Availability Cluster Manager.
Messages seen in SLES12 log after trying to start pacemaker.service and failing to start / join the cluster.
sbd: : WARN: Found fencing message - aborting start-up. Manual intervention required!
sbd: : WARN: Servant for pcmk (pid: 34826) has terminated
sbd: : WARN: Servant for <path to sbd device > (pid: 34824) has terminated
sbd.sh: sbd failed; please check the logs.
sbd.sh: SBD failed to start; aborting.
systemd: sbd.service: Control process exited, code=exited status=1
Need to find out <SBD_DEVICE> which can be found in /etc/sysconfig/sbd file.
Syntax to be run on node that was previously fenced:
Example: sbd -d <SBD_DEVICE> message LOCAL clear
You may also issue the command from any node in cluster by specifying the node name instead of "LOCAL"
Syntax: sbd -d <DEVICE_NAME> message <NODENAME> clear
Example: sbd -d /dev/sda1 message node1 clear
Once the node slot is cleared, you should be able to start clustering.
SLES114: rcopenais start
SLES12+: systemctl start pacemaker.service
## Default: always Options: always, clean
# Specify the start mode for sbd. Setting this to "clean" will only allow sbd to start if it was not previously fenced.
See the -S option in the man page.
Option for SLES11 /etc/sysconfig/sbd
SBD_OPTS="-W -P -S 1"
# -S 1 - set the start mode < Reference: man sbd >
# If set to one, sbd will only start if the node was previously shutdown cleanly (as indicated by an exit request message in the slot), or if the slot is empty. A reset, crashdump, or power-off request in any slot will halt the start up.
