I had 3 units before. After an upgrade from juju 2.9 -> 3.1 the unit vault/2 had a problem and I deployed the unit again. Unfortunately, the unit could not join the cluster (https://bugs.launchpad.net/vault-charm/+bug/2017514). I have decided to remove the unit first until there is a solution.

Possibly the problems are related or have the same cause.
