6. Import the pool (with –f and –m options) RESULT: SUCCESS
root@drmachine:~# zpool import

root@drmachine:~# zpool status
zpooltest
pool: zpooltest
state: DEGRADED
status: One or more devices
are unavailable in response to persistent errors.
Sufficient replicas exist for the pool to continue functioning in a
degraded state.
action: Determine if the
device needs to be replaced, and clear the errors
using 'zpool clear' or 'fmadm repaired', or replace the device
with 'zpool replace'.
Run 'zpool status -v' to see device specific details.
