Title:
  Race condition in hacluster charm that leaves pacemaker down

Status in OpenStack hacluster charm:
  Fix Released
Status in corosync package in Ubuntu:
  Fix Released
Status in corosync source package in Xenial:
  Incomplete
Status in hacluster package in Juju Charms Collection:
  Invalid

Bug description:
  Symptom: one or more hacluster nodes are left in an executing state.
  Observing the process list on the affected nodes the command 'crm node list' is in an infinite loop and pacemaker is not started. On nodes that complete the crm node list and other crm commands pacemaker is started.

  See the artefacts from this run:
  https://openstack-ci-reports.ubuntu.com/artifacts/test_charm_pipeline/openstack/charm-percona-cluster/417131/1/1873/index.html

  Hypothesis: There is a race that leads to crm node list being executed
  before pacemaker is started. It is also possible that something causes
  pacemaker to fail to start.

  Suggest a check for pacemaker heath before any crm commands are run.
