Description of problem:
SBD does not work properly with new on-fail="demote" option in pacemaker

Comment 1 Klaus Wenninger 2020-06-23 14:34:11 UTC

no-quorum-policy="demote" comes with new on-fail="demote"

Binary resulting from current SBD-code (built against pacemaker-code without the new
no-quorum-policy) will just do nothing in case of quorum-loss if no-quorum-policy="demote"
which of course implies apparent danger of split-brain in the cluster.

Depending on the configured handling of warnings compilers will probably refuse building
sbd against pacemaker if it has the ne no-quorum-policy.

To prevent similar issues in future it is probably safest for sbd to handle unknown
no-quorum-policy values like no_quorum_suicide.
