On my vcenter2 I got all cleared on NFS02 now new NFS02 is mounted.
On my vcenter 1 I have two VMs think they have access to NFS02.
I ran this command on Powercli
get-vm -datastore NFS02
it returns nothing
NFS02 0.000 0.000
I am still unable to unmounts the datastore
Found the VMs have Snapshots from my Veeam backups
Deleted all snapshots and the NFS02 was removed from the VM's
I was then able unmounts the Data store and Add it back,
Now all good.
