Set Object Storage ring partition power values

You can only set the partition power parameter for new containers and their objects, so you must configure this value before initial deployment.

About this task

The default partition power value is 10. Refer to the following table to select an appropriate partition power if you use three replicas:

Table 1. Appropriate partition power values per number of available disks

Partition Power

Maximum number of disks

10

~ 35

11

~ 75

12

~ 150

13

~ 250

14

~ 500
Important

Setting an excessively high partition power value (for example, 14 for only 40 disks) negatively impacts replication times.

Procedure

Open your OpenStackControlPlane CR file, openstack_control_plane.yaml, and change the value for partPower under the swiftRing parameter in the swift template: 
apiVersion: core.openstack.org/v1beta1
kind: OpenStackControlPlane
metadata:
  name: openstack-control-plane
  namespace: openstack
spec:
  ...
  swift:
    enabled: true
    template:
      swiftProxy:
        replicas: 2
      swiftRing:
        partPower: 12
        ringReplicas: 3
...
  • Replace <12> with the value you want to set for partition power. Tip
    You can also configure an additional object server ring for new containers. This is useful if you want to add more disks to an Object Storage service deployment that initially uses a low partition power.
