After installing 8.0-RC1 (amd64) from USB stick this installation works

booting from the ZFS fails. The initial installation I did just this, on
another attempt I ran "gpart bootcode -b /boot/pbmr -p /boot/gptzfsboot
adX" on all disks before rebooting to see if that had any effect. The end
result is the same. After rebooting the machine I get the following
prompt(s):
ZFS: i/o error - all block copies unavailable
Invalid format
FreeBSD/i386 boot
Default: tank:/boot/kernel/kernel
boot:
Could you type "status" at this point and tell what it shows?
If I type status at this point I get:
pool: tank
config:
NAME STATE
tank ONLINE
raidz1 ONLINE
ad4p3 ONLINE
ad6p3 ONLINE
ad8p3 ONLINE
ad10p3 ONLINE
Which seems odd, since that's all the drives there are. So if it finds these it's already found all drives. My optimistic "Oh! I'll try and boot again" spirit was however crushed since it just results in the same error.
Kind regards,
Merijn
