[ClusterLabs] How to clean up failed fencing action?

[Andrei Borzenkov]

I'm using sbd watchdog and stonith-watchdog-timeout without explicit
stonith agents (shared nothing cluster). How can I clean up failed
fencing action?

Current DC: ha1 (version
2.0.1+20190408.1b68da8e8-1.3-2.0.1+20190408.1b68da8e8) - partition with
quorum

crm_resource requires resource which does not exist.
