Why a Persistent Volume Claim in Openshift stays in 'Pending' status, showing 'exceeded quota' error Message?

Solution Verified - Updated -

Issue

  • When creating a persistent volume claim ( PVC ), the request is left in pending status with an exceeded quotaerror message.
  • The output of the command oc describe pvc <pvc-name> provides further details on which quota limit is reached:
$ oc get pvc
