[rdo-users] [tripleo] Deployment update (node addition) after changing aggregate groups/zones

[Ruslanas Gžibovskis]

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.
