Subject: Re: Re: ceph status not showing correct
monitor services
I have two approaches in mind, first one (and preferred) would be to
edit the mon spec to first remove mon.a001s016 and have a clean state.
Get the current spec with:
ceph orch ls mon --export > mon-edit.yaml
Edit the spec file so that mon.a001s016 is not part of it, then apply:
ceph orch apply -i mon-edit.yaml
This should remove the mon.a001s016 daemon. Then wait a few minutes
or so (until the daemon is actually gone, check locally on the node
with 'cephadm ls' and in /var/lib/ceph/<FSID>/removed) and add it
back to the spec file, then apply again. I would expect a third MON
to be deployed. If that doesn't work for some reason you'll need to
inspect logs to find the root cause.
The second approach would be to remove and add the daemon manually:
ceph orch daemon rm mon.a001s016
Wait until it's really gone, then add it:
ceph orch daemon add mon a001s016
Not entirely sure about the daemon add mon command, you might need
to provide something else, I'm typing this by heart.

Hi Eugen,
Yes that is it. OSDs were restarted since mon a001s017 was reporting
is low on available space. How to update the mon map to add
mon.a001s016 as it is already online?
And how to update mgr map to include standby mgr.a001s018 as it is
also running.

Subject: Re: ceph status not showing correct monitor

Maybe it’s just not in the monmap? Can you show the output of:
ceph mon dump
Did you do any maintenance (apparently OSDs restarted recently) and
maybe accidentally removed a MON from the monmap?

Hi Anthony,
Seeing it since last after noon. It is same with mgr services as ,
"ceph -s" is reporting only TWO instead of THREE
Also mon and mgr shows " is_active: false" see below.
