FreeBSD real-big-one.office.furgon-center.ru 8.2-STABLE FreeBSD 8.2-STABLE #0: Fri Sep 2 11:02:24 MSD 2011 ighor at real-big-one.office.furgon-center.ru:/usr/obj/usr/src/sys/CUSTOM amd64
System was updated to 8.2-STABLE from 8.2-RELEASE and has ZFS RAIDZ2 with 6 hdds (500Gb each). Total capacity was (6-2)*500, approx 2T. Each hdd is conencted to one the same ICH10 controller, visible to BIOS and works stable. When one(any) HDD is removed system fails to boot from degraded ZFS RAIDZ2.
Remove one of 6 HDDs from RAIDZ2 on 8.2-STABLE - system will not boot from degraded RAIDZ2.
8.2-RELEASE works fine
