Chapter 2. Verifying your OpenShift Container Storage installation
Use this section to verify that OpenShift Container Storage is deployed correctly.
2.1. Verify that the pods are in running state
-
Click Workloads
Pods from the left pane of the OpenShift Web Console. Select openshift-storage from the Project drop down list.
The number of pods varies depending on the number of worker nodes deployed on OpenShift Container Platform.
When you need to override the cluster-wide default node selector for OpenShift Container Storage, you can perform the following steps in command line interface:
Specify a blank node selector for the
openshift-storagenamespace.oc annotate namespace openshift-storage openshift.io/node-selector=
$ oc annotate namespace openshift-storage openshift.io/node-selector=Copy to Clipboard Copied! Toggle word wrap Toggle overflow Delete the original pods generated by the
DaemonSets.oc delete pod -l app=csi-cephfsplugin -n openshift-storage oc delete pod -l app=csi-rbdplugin -n openshift-storage
oc delete pod -l app=csi-cephfsplugin -n openshift-storage oc delete pod -l app=csi-rbdplugin -n openshift-storageCopy to Clipboard Copied! Toggle word wrap Toggle overflow
Verify that the following pods are in running and completed state by clicking on the Running and the Completed tabs:
| Component | No. of pods | Name of the pod |
|---|---|---|
| OpenShift Container Storage Operator | 1 |
|
| Rook-ceph Operator | 1 |
|
| NooBaa | 2 |
|
| Mon | 3 |
|
| CSI | 10 |
|
| OSD | 3 |
|
| rook-ceph-mgr | 1 |
|
| mds | 2 |
|
| rook-ceph-drain-canary | 3 |
|
| rgw (listed only in VMware) | 1 |
