I’m trying to create a new ZFS pool from an existing one (the new one is 4k aligned and the old one is legacy 512b).
But, I can’t get it to boot! Not sure what I’m doing wrong.
I thought I could create the new pool, and use ‘zfs send/recv’ to copy the existing pool and then boot onto the new disk, but the kernel doesn’t load… :(.
Does anyone know what I’m doing wrong?
Here’s my recipe:
# gpart create -s gpt diskid/DISK-NEW-DISK
# gpart add -s 64K -t freebsd-boot diskid/DISK-NEW-DISK
# gpart add -t 8G freebsd-swap diskid/DISK-NEW-DISK
# gpart add -t freebsd-zfs diskid/DISK-NEW-DISK
# gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 diskid/DISK-NEW-DISK
# zfs create copy /dev/diskid/DISK-NEW-DISKp3
# zfs send -R oldpool@20141226 | zfs receive -duvF copy
# zpool set bootfs=copy/ROOT/default copy
That ought to do it, right? But, if I remove all the existing drives and try and boot on just the new drive, it gets nowhere. I see the ‘/‘, but it doesn’t spin and doesn’t time out. :(.
Any clues would be gratefully received.
Many thanks,
Joe
