Ok. Verbose boot output is available here: http://people.freebsd.org/~mr/boot_fail.txt http://people.freebsd.org/~mr/boot_success.txt Verbose pciconf output: http://people.freebsd.org/~mr/pciconf.txt Disksetup: Im booting from 4 equally GPT partitioned 3TiB Disks: (fs)(root) gpart show ada0 => 34 5860533101 ada0 GPT (2.7T) 34 990 1 freebsd-boot (495k) 1024 2098176 2 freebsd-swap (1.0G) 2099200 5858433928 3 freebsd-zfs (2.7T) 5860533128 7 - free - (3.5k) (fs)(root) zpool status boot pool: boot state: ONLINE scan: scrub repaired 0 in 5h2m with 0 errors on Mon May 30 08:03:43 2011 config: NAME STATE READ WRITE CKSUM boot ONLINE 0 0 0 raidz1-0 ONLINE 0 0 0 ada0p3 ONLINE 0 0 0 ada1p3 ONLINE 0 0 0 ada2p3 ONLINE 0 0 0 ada3p3 ONLINE 0 0 0 errors: No known data errors (fs)(root) zpool get bootfs boot NAME PROPERTY VALUE SOURCE boot bootfs boot/ROOT/root local # loader.conf: ... vfs.root.mountfrom="zfs:boot/ROOT/root" ...
