I did scrubbing on 9.2 kernel (before upgrade to 9.3)

Everything seems to be fine:

  scan: scrub repaired 0 in 25h3m with 0 errors on Wed Oct 22 15:54:55 2014

I installed bootcode with "standard" way:

gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 mfid0

I did it on 9.2, then on 9.3, then on 10.0.. results are the same.


Currently I’m booting from mfsbsd iso. After networking setup I’m doing:

zpool -R /mnt import zbackup
mount -t devfs none /mnt/dev
chroot /mnt

and my system works just fine, no issues with ZFS at all.
