Title:
  nfs-kernel-server mountd check only checks for nfsv3 via UDP, not TCP

Status in “nfs-utils” package in Ubuntu:
  New

Bug description:
  I recently disabled UDP on our NFS server by setting --no-udp (or -U)
  and all of a sudden I could no longer get nfsv3 mounts to work. It
  turns out that this happens because of the check in /etc/init.d/nfs-
  kernel-server:

          rpcinfo -u localhost nfs 3 >/dev/null 2>&1 ||
                  RPCMOUNTDOPTS="$RPCMOUNTDOPTS --no-nfs-version 3"

  That line only uses rpcinfo -u, so disabling UDP breaks the check. It
  should probably be something like:

         rpcinfo -u localhost nfs 3 >/dev/null 2>&1 ||
                  rpcinfo -t localhost nfs 3 >/dev/null 2>&1 ||
                  RPCMOUNTDOPTS="$RPCMOUNTDOPTS --no-nfs-version 3"
