This option is only meaningful when used with the
.Cm nfsv4
option.
.It Cm oneopenown
Make a minor version 1 of the NFS Version 4 protocol mount use a single OpenOwner
for all Opens.
This may be useful for a server with a very low limit on OpenOwners, such as
AmazonEFS.
It can only be used with an NFSv4.1 mount.
It may not work correctly when Delegations are being issued by a server,
but note that the AmazonEFS server does not issued delegations at this time.
.It Cm pnfs
Enable support for parallel NFS (pNFS) for minor version 1 of the
NFS Version 4 protocol.
