How is it possible to run a NFSv4 Server without rpcbind? I've read in the release notes of SLES12 SP1 about it but it's not working: https://www.suse.com/releasenotes/x8...E-SLES/12-SP1/ (Search for "NFSv4 only configuration")

What I've done so far:
node1:~ # cat /proc/fs/nfsd/versions
-2 -3 +4 +4.1 -4.2
Then I stop rpcbind and want to restart NFS, but NFS fails!

Any idea?
