Ceph » Orchestrator

This issue is being observed off late with recent Crimson builds pulled from Shaman, this was not a problem previously.

While adding external hosts to the cluster, the following error was observed

[ceph: root@ceph-hakumar-7gpxph-node1-installer /]# ceph orch host add ceph-hakumar-7gpxph-node1-installer 10.0.210.112 _admin crash alertmanager mon mgr prometheus grafana installer node-exporter

Interestingly, the issue is not observed when current host(installer/admin) is added with labels but only occurs when other nodes are being added to the cluster and the error complains about 'hostname' 'addr' arguments missing even though both have been provided in the ceph orch host add command
