I have two esx clusters. one is 5.1 and the other is 6.0. I am trying to add a datastore using nfs. the 6.0 can add the datastore without issue but when I try to access the datastore from the 5.1 cluster I get the following error:
The mount request was denied by the NFS server. Check that the export exists and that the client is permitted to mount it.
not sure why.
