Cause

The block storage is selected in the "Audit log storage".
The file storage should be selected in the "Audit log storage".

Environment

Data Virtualization (Watson Query) on Cloud pak for data

Diagnosing The Problem

The error message in c-db2u-dv-db2u-0 pod.
0/11 nodes are available: 11 pod has unbound immediate PersistentVolumeClaims. preemption: 0/11 nodes are available: 11 Preemption is not helpful for scheduling.

The PersistentVolumeClaim:  c-db2u-dv-auditlogs is Pending with this message.
message: waiting for a volume to be created, either by external provisioner "openshift-storage.rbd.csi.ceph.com"  or manually created by system administrator


Resolving The Problem

Create the instance with these storages.
Node storage : Block storage (ex:ocs-storagecluster-ceph-rbd)
Caching storage : Block storage (ex: ocs-storagecluster-ceph-rbd)
Audit log storage : File storage (ex: ocs-storagecluster-cephfs)
