The ceph-mon and ceph-osd charms for Juju support upgrading between Ceph
releases; the upgrade is a rolling upgrade, orchestrated through keys
managed via the Ceph MON cluster itself.
The upgrade triggers are based around the Ubuntu Cloud Archive pockets that
also host Ceph (see ), so its possible to online upgrade using the
firefly -> hammer
hammer -> jewel
jewel -> luminous
we're working on the upgrade from luminous to mimic at the moment (but that
should not be a heavy lift so should land real-soon-now).
If you are currently deployed on Xenial (which shipped with Jewel), you can
upgrade directly to Luminous by re-configuring the charms:
juju config ceph-mon source=cloud:xenial-pike
once that has completed (juju status output will tell you when):
juju config ceph-osd source=cloud:xenial-pike
I'd recommend testing the upgrade in some sort of pre-production testing
