I see there is a problem known and described in 
https://github.com/openshift/openshift-ansible/issues/5750 
 and I’ve added a 
comment to that.

OKD/3.11 - Metrics playbook not creating the PV for NFS

[Alan Christie]

Hi,

OpenShift ansible tag: openshift-ansible-3.11.152-1
Ansible: 2.7.13

I’m trying to install metrics using NFS as the storage back-end and, although 
the NFS export and PVC is created, it’s not creating the underlying PV, 
preventing the hawular-cassandra pod from starting.

Incidentally, everything’s fine with an NFS-based registry. Its export gets 
created along with the PV and PVC.

I see a registry-volume PV but no metrics-volume.

This may be a red-herring but when I look at the playbooks I can see the 
registry variable being used (openshift_hosted_registry_storage_volume_size) 
but I cannot see the metrics variable being used anywhere 
(openshift_metrics_storage_volume_size)…

$ grep openshift_metrics_storage_volume_size `find . -name "*.yml"`

./roles/openshift_facts/defaults/main.yml:openshift_metrics_storage_volume_size:
 '10Gi'

In my inventory my registry variables (which work) look like this…

openshift_hosted_registry_storage_kind: nfs
openshift_hosted_registry_storage_access_modes: ['ReadWriteMany']
openshift_hosted_registry_storage_nfs_directory: /nfs1
openshift_hosted_registry_storage_nfs_options: '*(rw,root_squash)'
openshift_hosted_registry_storage_volume_name: registry
openshift_hosted_registry_storage_volume_size: 200Gi

…and the metrics variables look like this...

openshift_metrics_install_metrics: yes
openshift_metrics_storage_kind: nfs
openshift_metrics_storage_access_modes: ['ReadWriteOnce']
openshift_metrics_storage_nfs_directory: /exports
openshift_metrics_storage_nfs_options: '*(rw,root_squash)'
openshift_metrics_storage_volume_name: metrics
openshift_metrics_storage_volume_size: 40Gi
openshift_metrics_storage_labels: [{'storage': 'metrics'}]

Have I missed something for this to work?

If metrics is broken for NFS I’ll create an issue on the openshift-ansible repo.
