While testing zfs, I got kmem panic and after reboot same errors appeared. OpenSolaris does not allow to boot from raidz and there can be only one vdev in bootable pool, so I decided to make two pools if I need raidz or multiple vdevs: - one root pool (8G) (mirror disk0 disk1 ... disk5) - one for data and other fs (raidz disk0 disk1 ... disk5) -- Artis Caune Everything should be made as simple as possible, but not simpler.
