Description Amar Tumballi 2018-06-21 10:13:56 UTC

Description of problem:

Compile with IPV6_DEFAULT:
$ gluster v set rep nfs.disable off
$ gluster v set rep nfs.register-with-portmap on
$ mount.nfs 192.168.1.102:/rep /mnt # => successfully as expected
$ mount.nfs [fe80::20c:29ff:feb9:fc0a%eth0]:/rep /tmp/nfs # => successfully as expected
$ umount /mnt
$ umount /tmp/nfs
$ gluster v set rep nfs.register-with-portmap off
$ mount.nfs 192.168.1.102:/rep /mnt # => failed as expected
mount.nfs: requested NFS version or transport protocol is not supported
$ mount.nfs [fe80::20c:29ff:feb9:fc0a%eth0]:/rep /tmp/nfs # should failed but successfully

The root cause is that, we missed rpcsvc_program_unregister_rpcbind6 in nfs_program_unregister_portmap_all function

Version-Release number of selected component (if applicable):
master

How reproducible:
100%

COMMIT: https://review.gluster.org/20263 committed in master by "Amar Tumballi" <amarts> with a commit message- nfs: add missing rpcsvc_program_unregister_rpcbind6

Otherwise, event if nfs.register-with-portmap is disabled, we could
also use ipv6 to mount nfs through portmap.
