Simplest way I've found to duplicate this:

In /etc/fstab:
sirius:/var/spool/bacula /m/bacula nfs rw,bg,intr,mntudp,noauto

This results in a UDP mount over IPv6.  (I need to use the explicit IPv4
address instead of the name to get an IPv4 mount.)  Then,

# mount /m/bacula
# df
[...]
sirius:/var/spool/bacula 0 0 0 100% /m/bacula
barsoom# stat /m/bacula
stat: /m/bacula: lstat: Input/output error
