Upgrading charms

Prior to performing either a Ceph upgrade or an operating system upgrade all charms should be upgraded to their latest stable revision, which is the default behaviour of the upgrade-charm command (this can potentially be a multi-revision upgrade). See Upgrade target revisions for more information.

Note:

The Ceph charms have been tested for single-step charm upgrades only (N+1).

The Juju command to use for upgrading charms is upgrade-charm. For extra guidance see Upgrade an application in the Juju documentation.

In terms of the upgrade order, begin with ceph-mon, after which the remaining charms can be upgraded in any order. If using a charm delivered via the Charmhub:

juju refresh ceph-mon

Verify the success of an upgrade before moving on to the next charm. Do this by inspecting the juju status command output.
