Resolution

Make sure the "role-master" is properly assigned in the "/srv/pillar/ceph/proposals/policy.cfg" file and set to the required master node. If it was needed to add / modify the "role-master" entry, it is required to first again run "salt-run state.orch ceph.stage.2" before running stage 3 again.

Cause

No or incorrect "role-master" entry in "/srv/pillar/ceph/proposals/policy.cfg".

Additional Information

If the master node is "master-node01.lab.domain" the below is an example entry needed in the policy.cfg file:

role-master/cluster/master-node01.lab.domain.sls
