It's a possibility... new attempt from usb live system:
gpart delete -i 3 nvd0
gpart delete -i 3 nvd1
gpart add -a 4k -s 50G -t freebsd-zfs -l zfs0 nvd0
gpart add -a 4k -s 50G -t freebsd-zfs -l zfs1 nvd1
sysctl vfs.zfs.min_auto_ashift=12
zpool create -m none -o cachefile=/var/tmp/zpool.cache zroot mirror /dev/gpt/zfs0 /dev/gpt/zfs1
zfs receive -Fud zroot < zroot.zfs
zpool set bootfs=zroot/ROOT/default zroot
mount -t zfs zroot/ROOT/default /mnt
cp /var/tmp/zpool.cache /mnt/boot/zfs/zpool.cache
umount /mnt
reboot
Unfortunately, this didn't change anything. I'm still getting the
Trying to mount root from zfs:zroot/ROOT/default []...
Mounting from zfs:zroot/ROOT/default failed with error 6.
error :(
Any other ideas....?
Cheers,
Markus
