Drive is failing - Stripe Config - Can I replace?

[evader]

I think I have 2 drives failing. One more than the other.
I just added a 10tb drive to the NAS last month so I have tons of free space. Would I be able to take the 2tb and 3tb drive out?

Here's my Zpool status info

Code:

% zpool status
  pool: NAS
 state: ONLINE
status: One or more devices has experienced an error resulting in data
		corruption.  Applications may be affected.
action: Restore the file in question if possible.  Otherwise restore the
		entire pool from backup.

Hope you got a good backup!
You might be better off scrubbing everything and building a new z2 zpool
It would also help if you posted specifics of your build

No. You cannot remove vdevs. No exceptions (not yet, at least).

As @Ericloewe says, no, you can't remove them. You can, however, replace them with non-failing disks. Though the better answer would be to rebuild your pool with some redundancy.

All options are bad in this case. First, backup whatever critical data you can while it is running.

After that, you can try shutting down, removing the really bad drive, putting it in another system with a blank, good disk, and running ddrescue on it. Make sure you don't mixup the disks, or enter commands backwards, or you will erase the disk instead of copy it. With luck, some of those bad blocks will manage to read. When ddrescue has gotten as far as it will, put the new copy disk into FreeNAS and start up the pool.

Hopefully you can then backup most of the data, and then start over.
