I'm not sure if this Ubuntu version is rc4 or older.
Below is a script that you can use to reproduce the issue. It must be
run as root, of course.
dd if=/dev/zero of=zvol_test.img bs=100M count=1
zpool create zvol_test `pwd`/zvol_test.img
zfs create -V 50M zvol_test/zvol
if [ -e /dev/zvol/zvol_test/zvol ] ; then
zpool export zvol_test
