After upgrade from 9-STABLE to 10.1-RELEASE I've faced a problem.
On first boot the operation system starts normally. After reboot the
kernel is loaded but fails to mount root file system. The following
message is the last I can see.
Trying to mount root from zfs:red []...
Then the system reboots.
I can boot from USB memory stick and import zfs pool.
# zpool import -R /mnt -N red
After that the system boots only once and then a reboot loop repeats.
After the scrub 'zfs status' shows no error.

After upgrade to 10.1-RELEASE-p4 and 10.1-STABLE I can see the same.
Could anyone suggest how to repair zpool?
If it's needed I can provide more information.
