[ClusterLabs] Antw: [EXT] Final Pacemaker 2.0.5 release now available

[Reid Wahl]

Have you tried `crm_mon -s`?

# crm_mon --help-all | grep ' \-s'
  -s, --simple-status               Display the cluster status once as
a simple one line output (suitable for nagios)

Caveat: This isn't without flaws.
  - Bug 1576103 - `crm_mon -s` prints "CLUSTER OK" when there are
unclean (online) nodes
(https://bugzilla.redhat.com/show_bug.cgi?id=1576103)
  - `crm_mon -s` prints `"CLUSTER OK"` when there are nodes in
`UNCLEAN (online)` status
(https://access.redhat.com/solutions/3441221)

I dunno if Check CRM still works, given that it was last updated 7 years ago:
