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)
8388770 20971520 3 freebsd-zfs (10G)
29360290 943718400 4 freebsd-zfs (450G)
973078690 3694445 - free - (1.8G)

I hope that it helps to somebody with similar problem.
