I'm setting up a small test lab for HA Openstack environment based on Queens and CentOS 7 (to be the best similar with OSP 13, as my target). Director is CentOS 7.8 with ansible ansible-2.6.19-1.el7.ans.noarch and undercloud deployed.

Idea is to have 2 compute, 3 controllers, 3 ceph storage nodes

As the first step of overcloud deploy the correct 3 ceph nodes candidates for OSD role are powered on and begin to be configured, but at a certain point I have with this error
