I typically don't see this when I do OSD replacement. If you do a mgr
failover ("ceph mgr fail") and wait a few minutes does this still show up?
The stray daemon/host warning is roughly equivalent to comparing the
daemons in `ceph node ls` and `ceph orch ps` and seeing if there's anything
in the former but not the latter. Sometimes I have seen the mgr will have
some out of data info in the node ls and a failover will refresh it.
