I can mount my ZFS storage. I copy /boot from ZFS storage to flash and now kernel booted from flash fine, after that ZFS storage mounted as / and all work. zpool scrub don't detect any problems. zpool status wrote "No known data errors". But it too slowly and I want normally boot from ZFS storage without loading kernel from flash. How can I fix "ZFS: i/o error all block copies unavailable" ?
