[CentOS] NFS, acls, proto, and "kernel: svc: unknown version"

[Stephen Towler]

Hi all,

 1) My NFS3 clients don't display or obey existing non-POSIX ACLs on
 files of NFS3-mounted exports.

 2) setfacl on the client throws error and fails :
 # setfacl -m u:stowler:rw testfile.text
 setfacl: testfile.text: Operation not supported

 3) at time of client mount the server's /var/log/messages shows
 "kernel: svc: unknown version (3)".


 Any thoughts greatly appreciated. Will be happy to provide more
 configs in addition to below.
 Conditions exist whether export is mounted as tcp or udp.
