How to increase size of an existing Persistant Volume Container

Increasing the size of an existing PVC

Basic steps:

shut down apps using storage
backup current storage content (you can use oc login + oc get pods + oc rsync :/
create a new pvc for under a new name
update the deployment config and add the new pvc to be mounted under a new name (volume and volumeMounts)
oc rsh into the pod and verify both mounts are there (or check in the pathfinder gui)
oc rsh to pod and copy content to new mount
update the deployment config and remove old mount and mount new increased pvc to old location.
verify

See write-up by Kuan Fan at

for a good example for a postgress pvc increase.
