Configure o ZFS no FreeBSD do bsd-rescue

Question

Eu tenho um servidor da OVH e tenho o seguinte procedimento para configurar o ZFS no FreeBSD10 no servidor OVH, seguindo o link

Criando um sistema de arquivos ZFS inicializável

zpool destroy zroot
gpart destroy -F ada0
gpart destroy -F ada1

gpart create -s gpt ada0
gpart create -s gpt ada1

gpart add -b 34 -s 64k -t freebsd-boot ada0
gpart add -s 8G -t freebsd-swap -l swap0 ada0
gpart add -t freebsd-zfs -l disk0 ada0

gpart add -b 34 -s 64k -t freebsd-boot ada1
gpart add -s 8G -t freebsd-swap -l swap1 ada1
gpart add -t freebsd-zfs -l disk1 ada1

gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada0
gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada1

Criar zroot do pool do ZFS

mkdir /tmp/zroot
zpool create -o cachefile=/boot/zfs/zpool.cache -m none -f zroot mirror /dev/gpt/disk0 /dev/gpt/disk1
zpool set bootfs=zroot zroot
zfs set checksum=fletcher4 zroot
zfs set mountpoint=/tmp/zroot zroot

zfs create -o compression=on -o exec=on -o setuid=off zroot/tmp

Instalando o FreeBSD no sistema de arquivos ZFS

zfs create -o compression=on -o exec=on -o setuid=off zroot/tmp

chmod 1777 /tmp/zroot/tmp

zfs create zroot/usr

zfs create zroot/var
zfs create -o compression=lz4 -o exec=off -o setuid=off zroot/var/crash
zfs create -o exec=off -o setuid=off zroot/var/db
zfs create -o compression=lz4 -o exec=on -o setuid=off zroot/var/db/pkg
zfs create -o exec=off -o setuid=off zroot/var/empty
zfs create -o compression=lz4 -o exec=off -o setuid=off zroot/var/log

zfs create -o compression=gzip -o exec=off -o setuid=off zroot/var/mail
zfs create -o exec=off -o setuid=off zroot/var/run
zfs create -o compression=lz4 -o exec=on -o setuid=off zroot/var/tmp

chmod 1777 /tmp/zroot/var/tmp

zpool export zroot

zpool import -o cachefile=/tmp/zpool.cache zroot

cd /tmp/zroot
mkdir fileinstall
cd fileinstall

Quando reinicio o sistema, não consigo aceder ao mesmo e ao erro no ecrã de gestão da OVH, mas como não tenho acesso ao KVM, não consigo ver os erros.

Há algo que eu tenha perdido no meu procedimento?

ok, eu perdi o 'eco' defaultrouter="XXX.XXX.XXX.254" 'caso contrário, tudo funciona bem
