FreeBSD 10.3. ZFS.

  # zpool status
   pool: database
  state: UNAVAIL
status: One or more devices are faulted in response to persistent 
errors.  There are insufficient replicas for the pool to
         continue functioning.
action: Destroy and re-create the pool from a backup source. Manually 
marking the device
         repaired using 'zpool clear' may allow some data to be recovered.
   scan: none requested

         NAME               STATE     READ WRITE CKSUM
         database           UNAVAIL      0     0     0
           mirror-0         UNAVAIL      0     0     0
             gpt/database0  FAULTED      0     0     0  too many errors
             gpt/database1  FAULTED      0     0     0  too many errors

disks can be read, can I somehow recover data from the pool?
