Hi, what's your ceph version? You probably don't have host labels set (check 'ceph orch host ls') and cephadm tries to copy a keyring to admin hosts with the _admin label [1]. Also check out how to put keyrings under management [2], I haven't dealt with that too intense yet. But basically it states:

Starting from versions 16.2.10 (Pacific) and 17.2.1 (Quincy), in addition to the default location /etc/ceph/ cephadm also stores config and keyring files in the /var/lib/ceph/<fsid>/config directory. It is usually a good idea to store a copy of the config and client.admin keyring on any host used to administer the cluster via the CLI. By default, cephadm does this for any nodes that have the _admin label (which normally includes the bootstrap host).

3/3/23 2:13:53 AM[WRN]unable to calc client keyring client.admin placement PlacementSpec(label='_admin'): Cannot place : No matching hosts for label _admin

I keep seeing this warning in the logs. I’m not really sure what action to take to resolve this issue.

Thanks -jeremy
