Chapter 4. Creating VolumeReplicationClass resource
The VolumeReplicationClass is used to specify the mirroringMode for each volume to be replicated as well as how often a volume or image is replicated (for example, every 5 minutes) from the local cluster to the remote cluster.
Note
This resource must be created on the Primary managed cluster and the Secondary managed cluster.
Procedure
Save the following YAML to filename
rbd-volumereplicationclass.yaml.apiVersion: replication.storage.openshift.io/v1alpha1 kind: VolumeReplicationClass metadata: name: odf-rbd-volumereplicationclass spec: provisioner: openshift-storage.rbd.csi.ceph.com parameters: mirroringMode: snapshot schedulingInterval: "5m" # <-- Must be the same as scheduling interval in the DRPolicy replication.storage.openshift.io/replication-secret-name: rook-csi-rbd-provisioner replication.storage.openshift.io/replication-secret-namespace: openshift-storageCreate the file on both the managed clusters.
$ oc create -f rbd-volumereplicationclass.yaml
Example output:
volumereplicationclass.replication.storage.openshift.io/odf-rbd-volumereplicationclass created
