Switch from NFS3 to NFS4.1 VMware datastores

[thomasb82]

Hi guys,

just curious, what is needed to change volumes used for VMware datastores with NFS3 to run with NFS 4.1?

Simple unmount on both ends, enable 4.1 support on NetApp and mount again?

Thanks!

You need to mount a new datastore on NFSv4.1 and migrate the VMs using storage vmotion.

You can just unmount and remount, but the caveat in the documentation states you must unmount from all hosts as you cannot have an export mounted in different nfs versions.
