[ClusterLabs] SBD fencing not working on my two-node cluster

[Philippe M Stedman]

Hi Klaus,

Thank you very much, that is what the problem was, Pacemaker was using
short hostnames, but SBD was using fully qualified hostnames. I am able to
successfully fence the host now that they both agree on hostname values.

Thanks,

If what you're getting doesn't match the node-names as pacemaker
sees them you can enforce the names used by sbd in the config-file
with the '-n' option. (alternatively setup pcmk_host_map)
