[ceph-users] excluding from host_pattern

Hi, I wonder if it is possible to define a host pattern, which includes the host names ceph01…ceph19, but no other hosts, especially not ceph00. That means, this pattern is wrong: ceph[01][0-9] , since it includes ceph00. Not really a problem, but it seems that the "“host-pattern” is a regex that matches against hostnames and returns only matching hosts"¹ is not defined more precisely in the docs. 1) https://docs.ceph.com/en/latest/cephadm/host-management/
