Configure initial defaults

The Block Storage service (cinder) has a set of initial defaults that should be configured when the service is first enabled. They must be defined in the main customServiceConfig section. Once deployed, these initial defaults are modified using the openstack client.

Procedure

  1. Open your OpenStackControlPlane CR file, openstack_control_plane.yaml.
  2. Edit the CR file and add the Block Storage service global configuration.

    The following example demonstrates a Block Storage service initial configuration:

    apiVersion: core.openstack.org/v1beta1
kind: OpenStackControlPlane
metadata:
  name: openstack
spec:
  cinder:
    enabled: true
    template:
      customServiceConfig: |
        [DEFAULT]
        quota_volumes = 20
        quota_snapshots = 15

    For a complete list of all initial default parameters, see Initial default parameters.

  3. Update the control plane: 
    $ oc apply -f openstack_control_plane.yaml -n openstack
  4. Wait until RHOCP creates the resources related to the OpenStackControlPlane CR. Run the following command to check the status: 
    $ oc get openstackcontrolplane -n openstack

    The OpenStackControlPlane resources are created when the status is "Setup complete".

    Tip
    Append the -w option to the end of the get command to track deployment progress.

Configure initial default parameters such as volume types, quotas, and snapshot size limits when you first enable the Block Storage service.

Parameter Description

default_volume_type

Provides the default volume type for all users. The default type of any non-default value will not be automatically created. The default value is DEFAULT.

no_snapshot_gb_quota

Determines if the size of snapshots count against the gigabyte quota in addition to the size of volumes. The default is false, which means that the size of the snapshots are included in the gigabyte quota.

per_volume_size_limit

Provides the maximum size of each volume in gigabytes. The default is -1 (unlimited).

quota_volumes

Provides the number of volumes allowed for each project. The default value is 10.

quota_snapshots

Provides the number of snapshots allowed for each project. The default value is 10.

quota_groups

Provides the number of volume groups allowed for each project, which includes the consistency groups. The default value is 10.

quota_gigabytes

Provides the total amount of storage for each project, in gigabytes, allowed for volumes, and depending upon the configuration of the no_snapshot_gb_quota initial parameter this might also include the size of the snapshots. The default values, also count the size of the snapshots against this limit of 1000 GB.

quota_backups

Provides the number backups allowed for each project. The default value is 10.

quota_backup_gigabytes

Provides the total amount of storage for each project, in gigabytes, allowed for backups. The default is 1000.
