Environment

SUSE Linux Enterprise High Availability Extension 12 Service Pack 3

Situation

When a STONITH resource was configured using more than one SBD device the resource fails after starting. The following messages can be seen in /var/log/messages:

2017-12-18T13:48:49.067055+01:00 sles12cluster1 stonith: external/sbd device not accessible. 

Resolution

Cause

Parsing the list of SBD_DEVICE in /etc/sysconfig/sbd led to reading the variable twice. 

Additional Information

Note:  When configuring multiple SBD devices in the /etc/sysconfig/sbd configuration file,  the list of devices need to be separated by semi-colon and surrounded by quotes. 
Example:
SBD_DEVICE="/dev/disk/by-id/scsi-disk1; /dev/disk/by-id/scsi-disk2; /dev/disk/by-id/scsi-disk3"
