Chapter 7. Checking for Local Storage Operator deployments
OpenShift Container Storage clusters with Local Storage Operator are deployed using local storage devices. To find out if your existing cluster with OpenShift Container Storage was deployed using local storage devices, use the following procedure:
Prerequisites
-
OpenShift Container Storage is installed and running in the
openshift-storagenamespace.
Procedure
By checking the storage class associated with your OpenShift Container Storage cluster’s persistent volume claims (PVCs), you can tell if your cluster was deployed using local storage devices.
Check the storage class associated with OpenShift Container Storage cluster’s PVCs with the following command:
$ oc get pvc -n openshift-storage
Check the output. For clusters with Local Storage Operator, the PVCs associated with
ocs-devicesetuse the storage classlocalblock. The output looks similar to the following:NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGE db-noobaa-db-0 Bound pvc-d96c747b-2ab5-47e2-b07e-1079623748d8 50Gi RWO ocs-storagecluster-ceph-rbd 114s ocs-deviceset-0-0-lzfrd Bound local-pv-7e70c77c 1769Gi RWO localblock 2m10s ocs-deviceset-1-0-7rggl Bound local-pv-b19b3d48 1769Gi RWO localblock 2m10s ocs-deviceset-2-0-znhk8 Bound local-pv-e9f22cdc 1769Gi RWO localblock 2m10s
