Fixed the issue with the host_subset_size parameter in the configuration of
nova-controller being set to 30, which could cause scheduling issues.
Now, host_subset_size is set to 1 by default. If you previously did not
change the host_subset_size value, the issue resolution will apply
automatically. Otherwise, manually set host_subset_size to 1 as
described below.
To apply the issue resolution:
Open your Git project repository with the Reclass model on the cluster level.
In openstack/control.yml, set the host_subset_size parameter to
1:
nova:
controller:
host_subset_size: 1
Log in to the Salt Master node.
Apply the changes:
salt 'ctl*' state.apply nova
