The first deployment set all computes to zone named according to stack name, but later I have created Alpha01, Alpha02. And set according in node-info.yaml file. But still, it fails with message, that some compute is already present in zone Alpha01... like it cannot create such zone. And I say, yes captain, I know, I have created and added YOU into that zone... Maybe I need to do some "tweaks" to DB? just now thought about it.

Hi,

You will need to manually remove the hosts from the old zone ("Alpha01") before adding them to the new zone. A host can only belong to one AZ.

Thanks,

Ollie

Hi all,

Any thoughts on this one?

 

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.
