Issue/Introduction

Our NFS server ran out of disk space, actions were performed to clear some space, then we tried to restart dx services but unable to do so, many pods are in CrashLoopBackOff  and in the pod logs, we can see the "Permission denied" message as below:

 

kubectl  logs -ndxi dxi-postgresql-66fc6b647-q8npb
