Updated 8.2-STABLE, when there added ZFS v28

During the import did not work neither of the commands zfs or zpool.
Because of this, suffered all the zfs pools on this server.

# zpool import -fFX tank
Pool tank returned to its state as of понедельник, 23 мая 2011 г. 18:02:15.
Discarded approximately 401 minutes of transactions.


Problem #1
lost connection in the pool for gpt label


# zpool status tank
   pool: tank
  state: DEGRADED
status: One or more devices has been taken offline by the administrator.
         Sufficient replicas exist for the pool to continue functioning in a
         degraded state.
action: Online the device using 'zpool online' or replace the device with
         'zpool replace'.
  scan: none requested
config:

Problem #2
Low speed command "zpool scrub tank"

# zpool status tank
   pool: tank

         Sufficient replicas exist for the pool to continue functioning in a
         degraded state.

         'zpool replace'.
