Adding MONs

MONs are added via a new ceph-mon unit.

  1. Ensure that the cluster is in a healthy state. On any MON (such as the leader unit here) run a status check:

    juju ssh ceph-mon/leader sudo ceph status
  2. Add a containerised ceph-mon unit to existing machine #3:

    juju add-unit --to lxd:3 ceph-mon

Recall that a cluster should always have an odd number of MONs.


Similar to Adding OSDs, I think we should replace ceph-mon/1 by ceph-mon/leader here as well.
