Hi,
Assuming that you are using some version of diskless (man diskless), I
build NAS boxes using NanoBSD (man nanobsd) and in that setup, I need to
move the cache from /boot/zfs to /etc/zfscache so the cache can be mapped
to the files copied to the cfg partision. So I added the following file to
rc.d/zpool
---------------------------------------------------------------------------
#!/bin/sh
#
# $FreeBSD: $
#
# PROVIDE: zpool
# REQUIRE: hostid
# BEFORE: zvol
# KEYWORD: nojail
. /etc/rc.subr
name="zpool"
rcvar="zfs_enable"
start_cmd="zpool_start"
required_modules="zfs"
zpool_start()
{
if [ ! -z "$zpool_cache" -a -r "$zpool_cache" ]; then
zpool import -c $zpool_cache -a
fi
}
load_rc_config $name
run_rc_command "$1"
---------------------------------------------------------------------------
This works very well for a disk server from USB, CF or mSATA SSD.
I am not sure the BEFORE tag was required to make sure that this is the
first ZFS related script run, before zvol, as zpool is sorted before zvol
but I was not sure exactly how rcorder sorts.

Greetings!
I have a FreeBSD 9 system with 3 different ZFS pools on it. I am
booting from a ro CF Card w/o any major issues, the problem I am
encountering is that zroot needs to be mounted at boot first, because
it contains /usr, zhome and tank contain other various sub-partitions
of /usr.
Also, zroot causes me a lot of problems when I try to do "zpool
import", when zpool gets to probing zroot, I get g_vfs errors printed
to the console and the hacnine hangs till I reset it (which is
obviously not acceptable behavior.) I was able to get around this when
booting to my cf card by making / ro, which was my intention all along
for that media.) I suspect this happens because there is a on that
volume that is trying to replace something on / on either the USB boot
img or on my CF card and this might be causing either to freak out.
So I dunno what to do to get this working the way it should and some
guidence would be greatly appreciated!
