Oh, and if it matters, the disks in the raidz pool give errors like
"secondary GPT table is corrupt or invalid" and "secondary GPT header
is not in the last LBA" when booting. Not sure if these happened
already before I did the reinstall, since I hadn't had any problems
and hadn't checked the dmesg then.
