How to change the RECLAIMPOLICY to 'Retain' in the StorageClasses created by ODF?

Solution Verified - Updated -

Issue

  • When ODF is installed, it creates three or four storage classes, depending on the platform where it's deployed. The example below comes from a bare-metal installation, where four ODF storage classes are available:

    NAME                          PROVISIONER                             RECLAIMPOLICY   VOLUMEBINDINGMODE      ALLOWVOLUMEEXPANSION   AGE
ocs-storagecluster-ceph-rbd   openshift-storage.rbd.csi.ceph.com      Delete          Immediate              true                   15m
ocs-storagecluster-ceph-rgw   openshift-storage.ceph.rook.io/bucket   Delete          Immediate              false                  2d3h
ocs-storagecluster-cephfs     openshift-storage.cephfs.csi.ceph.com   Delete          Immediate              true                   2d3h
openshift-storage.noobaa.io   openshift-storage.noobaa.io/obc         Delete          Immediate              false                  2d3h

  • As seem above, the 'Reclaim policy' set is 'Delete' by default. How to change this property to 'Retain', after the installation?
