Creating additional data pools

Before you begin

Fusion Data Foundation operator is installed and OpenShift Data Foundation storage cluster in provider mode is created.

About this task

You can create additional data pools for the Ceph file system.

Procedure

In the provider storage cluster CR, add additional data pools under spec.managedResources Ceph Filesystems:

For example:

additionalDataPools:
    - name: add-pool
      application: ""
      erasureCoded:
        codingChunks: 0
        dataChunks: 0
      mirroring: {}
      quotas: {}
      replicated:
        size: 0
      statusCheck:
        mirror: {}

In the client storage cluster CR, edit the storageProfile to use the additional data pool that is created in the provider cluster.
For example:
```
apiVersion: ocs.openshift.io/v1alpha1
kind: StorageClaim
metadata:
  name: claim-t3
spec:
  storageClient: ocs-storagecluster
  storageProfile: add-pool
  type: sharedfile
```
This creates a new set of storage classes with the new additional data pool and when the applications use these storage classes, the block pool is used to store the data on the newly configured device.
To verify that the new storage classes are created, perform the following steps:
1. Click Storage → StorageClasses.
2. Verify that a new storage class with the same name as the storage claim is created.
