Hi All,
i have 4 ESX 4 in cluster, After migrate VMs to new storage i try to unmount NFS, it is success in all Share Except one say the datastore in use.
i try restaert esx and esx magmnet also the vcenter services with no result.
Check that any iso files (from this datastore) is not attached in a VM.
the data store is empty.
Please try unmounting it from CLI
1. List the datastore name
# esxcfg-nas -l
2. Delete the datastore
# esxcfg-nas -d <NFS_Datastore_Name>
or
# esxcli storage nfs remove -v vol_nfs-2
