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,
