Title:
Race condition in hacluster charm that leaves pacemaker down
Status in OpenStack hacluster charm:
Fix Committed
Status in corosync package in Ubuntu:
New
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.
