>Description:
Upon reboot, zvols disappear on zfs-on-root systems (not tested on
non-zfs-on-root systems)
a zfs volinit cures this problem. zfs volinit is safe to run multiple times
Also see some discussion at
http://lists.freebsd.org/pipermail/freebsd-current/2009-July/009589.html
>How-To-Repeat:
Create zvol (zfs create -V 1g zpool/zvol)
reboot
see that /dev/zvol has gone
