Hi all After power down on FreeBSD 8.2-STABLE #6 (now updated to #7, but problem standing) I can't boot from ZFS v28. gptzfsboot wrote boot: ZFS: i/o error all block copies unavailable instead boot: qroot:/boot/kernel/kernel I download FreeBSD 9.0-BETA1 image and boot from it. 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" ? Now I have FreeBSD QUAZIS.SNNLAN.local 8.2-STABLE FreeBSD 8.2-STABLE #7: Fri Aug 12 23:27:33 EEST 2011 root@QUAZIS.SNNLAN.local:/usr/obj/usr/src/sys/main8 i386 => 34 976770988 ad4 GPT (465G) 34 256 1 freebsd-boot (128k) 290 16777216 2 freebsd-swap (8.0G) 16777506 959993516 3 freebsd-zfs (457G)
