NFS datastore that shows inaccessible does not unmount from the vSphere Client

Products

• VMware vSphere ESXi

Issue/Introduction

An NFS datastore shows inaccessible in the vSphere inventory and no hosts show the datastore mounted

Environment

7.0

Cause

NFS is unmounted outside of the vSphere Client unmount workflow and the datastore is never removed from inventory properly.  The proper workflow is detailed in the documentation below:

Resolution

Manually remount the NFS datastore to a single host per the following KB, at which point the NFS datastore should be accessible to remaining hosts from the vSphere Client and be unmounted using the proper workflow:
