Hi all.

After changing the host aggregate group and zone, I cannot run OpenStack deploy command successfully again, even after updating deployment environment files according to my setup.

I receive error bigger one in [0]:

2020-12-02 10:16:18.532419 | 52540000-0001-cf95-492f-0000000003ca |      FATAL | Nova: Manage aggregate and availability zone and add hosts to the zone | undercloud | error={"changed": false, "msg": "ConflictException: 409: Client Error for url: http://10.120.129.199:8774/v2.1/os-aggregates/1/action, Cannot add host to aggregate 1. Reason: One or more hosts already in availability zone(s) ['Alpha01']."}

I was following this link [1] instructions for "Configuring Availability Zones (AZ)" steps to modify with OpenStack commands. And zone was created successfully, but when I needed to add additional nodes, executed deployment again with increased numbers it was complaining about an incorrect aggregate zone, and now it is complaining about not empty zone with error [0] mentioned above. I have added aggregate zones into deployment files even role file... any ideas?

Also, I think, this should be mentioned, that added it after install, you lose the possibility to update using tripleo tool and you will need to modify environment files with.
