Hi,
After upgrading to
9.2-STABLE #8 r259396: Sun Dec 15 01:20:44 EET 2013 GENERIC amd64
the system in question didn't come up:
ZFS: i/o error - all block copies unavailable
ZFS: can't read MOS of pool zroot
gptszfsboot: failed to mount default pool zroot
GPTZFSBoot setup like in the wiki, except I didn't bothered with gnop.
At the time of the upgrade the boot disk was ada0.
Luckly I can boot without problems from any of the other 2 disks.
Pool history:
1. started as a mirror over partitions on a 500GB HDD and a 1TB HDD
(still present in the system - ada1 bellow, can boot from it)
2. the 500GB was replaced by ada0, the system was able to boot from the
new disk; the pool extended via zfs online -e
3. ada1 (1TB) was replaced by ada2, the pool not extended yet
--- At this point I could boot from any of the disks.
4. zfs scrub the mirror without any error
5. upgrade
(svn up, buildworld, buildkernel, installkernel, mergemaster -p,
installworld, mergemaster -iU, delete-old-libs, update ports .ko
modules, reboot)
6. The error above.
7. Boot from ada2, gpart bootcode ... ada0, still the same error.
I have snapshots of the pool from before the upgrade, so I could try to
rollback and see if it makes any difference. (The machine is in
production so I can't do it on the spot).
