After a loss in power, I rebooted my NAS and it was no longer able to mount my main pool. The output of a zfs import was as follows:

Code:
   pool: Pool

	 id: 17492755298469433864

  state: FAULTED

 status: The pool metadata is corrupted.

 action: The pool cannot be imported due to damaged devices or data.

		The pool may be active on another system, but can be imported using

		the '-f' flag.

   see: http://illumos.org/msg/ZFS-8000-72

 config:


		Pool											FAULTED  corrupted data

		  mirror-0									  ONLINE

			gptid/d9667391-14f9-11e3-bfdd-00012e2ff432  ONLINE

			gptid/d44c1fea-dee9-11e7-8b50-00012e2ff432  ONLINE

		  mirror-1									  ONLINE

			gptid/8c26dec8-168a-11e3-acff-00012e2ff432  ONLINE

			gptid/8cec3751-168a-11e3-acff-00012e2ff432  ONLINE

		  mirror-2									  ONLINE

			gptid/dd6c7a84-f3e4-11e3-95f0-00012e2ff432  ONLINE

			gptid/de70dc6b-f3e4-11e3-95f0-00012e2ff432  ONLINE


I tried to follow the instructions and import with various flags, including zpool import -fF Pool and zpool import -fFX Pool, but all attempts gave the following error:
Code:
cannot import 'Pool': I/O error

		Destroy and re-create the pool from

		a backup source.


Is this really the only resolution or is there something else I can do to try and recover? Any suggestions would be appreciated. Let me know if I should post more info to help troubleshoot this.

You can try to import it read-only, if that's more convenient than restoring from backup. Some corruption, like spacemap corruption, prevents writes but still allows for reads.

Thanks for the suggestions. Gave the zpool import -f -o readonly=on Pool a shot, it gave me the same error message as the other -f import attempts:
Code:
cannot import 'Pool': I/O error
		Destroy and re-create the pool from
		a backup source.

As requested, the output of running zdb -l /dev/daXp2 for each drive. Put in a text file due to length, but let me know if it's easier to look through if I break it into parts/posts.

Copy the output and place it in code tags.

At the power failure, would you say the NAS was idle, under some load, or heavily loaded? How quickly does the error come back on standard zpool import -f?

I believe it was likely idle, but there is a chance it was under some light load. The error comes back immediately.
