[Vladislav V. Prodan]

how to change the status of "FAULTED" on "DEGRADED"?

# zpool import
   pool: tank
     id: 17628573572433446879
  state: FAULTED
status: One or more devices are missing from the system.
action: The pool cannot be imported. Attach the missing
         devices and try again.
         The pool may be active on another system, but can be imported using
         the '-f' flag.
