systemctl enable sbd.serviceRestart the cluster stack as sbd.service will start as a dependency of pacemaker.service.
systemctl stop pacemaker | crm cluster stop systemctl start pacemaker | crm cluster start
The cluster was created without SBD so the "sbd.service" was not enabled.
To see the node name in the SBD disk slot, you can execute the following command to see cluster nodes allocated slots for each quorum disk.
sbd -d <device> listExample:
node1:/ # sbd -d /dev/disk/by-id/scsi-360014052ca3680347a74e9eac60bf0ce-part1 -d /dev/disk/by-id/scsi-360014052ca3680347a74e9eac60bf0ce-part2 -d /dev/disk/by-id/scsi-360014052ca3680347a74e9eac60bf0ce-part3 list 0 node1 clear 1 node2 clear 0 node1 clear 1 node2 clear 0 node1 clear 1 node2 clearTo see which devices are configured for SBD, reference the "SBD_DEVICE=" in the /etc/sysconfig/sbd configuration file. For multiple disks make sure each disk is separated with a semi-colon and surrounded by quotes.
