cephadm deploys the containers with --rm so they will get removed if you
stop them. As for getting the 2nd mgr back, if it still lists the 2nd one
in `ceph orch ps` you should be able to do a `ceph orch daemon redeploy
<mgr-daemon-name>` where <mgr-daemon-name> should match the name given in
the orch ps output for the one that isn't actually up. If it isn't listed
there, given you have a count of 2, cephadm should deploy another one. I do
see in the orch ls output you posted that it says the mgr service has "2/2"
running which implies it believes a 2nd mgr is present (and you would
therefore be able to try the daemon redeploy if that daemon isn't actually
there).
Is it still reporting the duplicate osds in orch ps? I see in the cephadm
ls output on ceph1 that osd.2 isn't being reported, which was reported as
being on ceph1 in the orch ps output in your original message in this
thread. I'm interested in what `ceph health detail` is reporting now as
well, as it says there are 4 stray daemons. Also, the `ceph orch host ls`
output just to get a better grasp of the topology of this cluster.
