Thank you guys, you are right. The BIOS provides only 1 disk to the loader!
I checked it from loader prompt by lsdev (booted from USB external HDD).
So I will try to make a small zpool mirror for root and boot (if ZFS mirror
can be made of 4 providers instead of two) and the rest will be in RAIDZ.
If that fails, I will go my old way with internal USB flash disk with UFS
for booting and RAIDZ of 4 disks for storage as I did it few years ago with
7.0 or 7.1.
You seem to be booting from disks attached to some sort of add-on
card. Sometimes those have per-disk 'bootable' option in their own
extension ROM. You may investigate yours. Perhaps all you need to do
is just tweak controller settings.
Advanced controller settings allows me to choose which disk will be
bootable - but I can mark just one of them, not all.
So my working setup is made from 2 pools. First is 4 way ZFS mirror for
/ (root), second is RAIDZ for the rest.
(plus swap made on the top of gmirrored partitions)
Each disk has following partitions:
# gpart show da0
=> 34 976773101 da0 GPT (465G)
34 128 1 freebsd-boot (64k)
162 8388608 2 freebsd-swap (4.0G)
