at that point the running mons were still on octopus.

I restored the test cluster to the previous state, ran the updates
again:

root@mceph05:~# grep ceph-mgr:  /var/log/dpkg.log

at 12:54:42, something restarted the ceph-mgr systemd unit:

Looks more like a service restart at install time than a ceph-mgr self-respawn.

[ceph-users] Re: mgr service restarted by package install?

2022-07-18 Thread Dan van der Ster
Hi,

It probably wasn't restarted by the package, but the mgr itself
respawned because the set of enabled modules changed.
E.g. this happens when upgrading from octopus to pacific, just after
the pacific mons get a quorum:

2022-07-13T11:43:41.308+0200 7f71c0c86700  1 mgr handle_mgr_map
respawning because set of enabled modules changed!

Cheers, Dan
