Mounting Root Failed

[markfisher]

Hi

I'm trying to set[]up ZFS on my computer using this: http://www.keltia.net/howtos/mfsbsd-zfs91/ (no mirroring). I'm skipping the beginning section(s) and start from the section "Partitioning the drives".

I'm using FreeBSD-9.1-RELEASE-amd64-memstick.img copied onto a USB memory stick and boot up the computer from it. From bsdinstall, I go directly to "Shell".

Here are the steps:

mount -rw /
kldload zfs
kldload geom_eli

gpart delete -i 1 ada1
gpart delete -i 2 ada1
gpart delete -i 3 ada1
gpart delete -i 4 ada1
gpart destry ada1
dd if=/dev/zero of=/dev/ada1 bs=512 count=10 # Not necessary :-)

gpart create -s gpt ada1
gpart add -b 40 -s 64K -a 4k -t freebsd-boot ada1
gpart add -s 2G -a 4k -t freebsd-zfs -l zboot0 ada1
gpart add -s 4G -a 4k -t freebsd-swap -l swap0 ada1
gpart add -a 4k -t freebsd-zfs -l zpool0 ada1

gpart set -a bootme -i 2 ada1
gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada1

mkdir /root/keys
dd if=/dev/random of=/root/keys/boot.key bs=128k count=1
geli init -b -K /root/keys/boot.key -s 4096 -l 256 /dev/gpt/zpool0
geli attach -k /root/keys/boot.key /dev/gpt/zpool0

zpool create zboot gpt/zboot0
zpool create zpool gpt/zpool0.eli

geli_zpool0_keyfile0_load="YES"
geli_zpool0_keyfile0_type="gpt/zpool0:geli_keyfile0"
geli_zpool0_keyfile0_name="/boot/keys/boot.key"

In my /zpool/root/etc/sysctl.conf I have:

kern.maxvnodes=260000

In my /zpool/root/etc/rc.conf I have:

zfs_enable="YES"
geli_swap_flags="-e aes -l 256 -s 4096 -d"

In my /zpool/root/etc/fstab I have:

/dev/gpt/swap0.eli    none    swap    sw    0    0

After restarting the system can't mount root.

Thanks for the help.
