VMware Cannot Remove / Unmount an NFS Store

KB ID 0001479


After I had a datastore failure I needed to ‘unmount’ a datastore in my VMware 6.5 environment. But when I attempted to do so I got;

Operation Failed Datastore In Use

The “Remote Datastore” operation failed for the entity with the following error message.

The resource “Datastore-Name” is in use.


In use by what? Thanks for the assistance! Usually this happens because you have a VM with a VMDK in their datastore, or more likely, a VM has a CD mapped to an ISO that was in this datastore (which was my problem).

In “Datatstore View” > Select the offending Datastore > VMs > Eliminate them one by one.
