Wasn't amused when someone brought my attention to a Ceph cluster with a HEALTH_ERR state:
This is apparently a minor problem with the system not being able to submit telemetry data and the severity of this error is expected to be downgraded in future releases. To clear the error restart the mgr service on whichever node is currently active.
In the following example we should login to kvm1c and run 'systemctl restart ceph-mgr@kvm1c':
mgr: kvm1c(active, since 14h), standbys: kvm1b, kvm1a
