Can you check if you have this config-key?

ceph config-key get mgr/cephadm/upgrade_state

If you reset the MGRs, it might be necessary to clear this key,
otherwise you might end up in some inconsistency. Just to be sure.

Thanks. I’m trying to be extra careful since this cluster is
actually in use. I’ll wait for your feedback.

No, that's not necessary, just edit the unit.run file for the MGRs to
use a different image. See Frédéric's instructions:

But I'm not entirely sure if you need to clear some config-keys first
in order to reset the upgrade state. If I have time, I'll try to check
tomorrow, or on Monday.

Would I follow this process to downgrade?

Your cluster seems to be in an error state (ceph -s) because of an
unknown PG. It's recommended to have a healthy cluster before
attemping an upgrade. It's possible that these errors come from the
not upgraded MGR, I'm not sure.

Since the upgrade was only successful for two MGRs, I am thinking
about downgrading both MGRs back to 16.2.15, then retry an upgrade to
a newer version, either 17.2.8 or 18.2.4. I haven't checked the
snap_schedule error yet, though. Maybe someone else knows
that already.
