SOLVED ZFS Mirror Disk Sets Online but 'corrupted data.'

[Tiydude]

I would like to begin with thanking everyone who is taking the time to read this thread. Without further ado:
I recently had a disk go offline, but I got it back online with a reseat and had to resliver the pool. During the resliver,the disk became 'removed'. It kept on progressing, so I though it was fine. A bit later the pool showed up in storage, but with no zvols or shares under it. I detached it, and tried to reattach to no avail, so I had the bright idea to reboot during the resliver, to see if it would fix it, and forums suggested that would be fine.
Now, the situation is this:

Code:

root@freenas:~ # zpool import
   pool: HDD
	 id: 11250748561142489606
  state: FAULTED
 status: One or more devices were being resilvered.
 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.
 config:

		HDD												 FAULTED  corrupted data
		  mirror-0										  FAULTED  corrupted data
			gptid/a2eb439b-19c9-11e7-9e0f-408d5cc6e5d1.eli  ONLINE
			gptid/a8cfb85d-fad0-11e6-9551-408d5cc6e5d1.eli  ONLINE
		  mirror-1										  FAULTED  corrupted data
			9994001295554260855							 UNAVAIL  cannot open
			gptid/ddf1c8e2-76d7-11e8-b59d-408d5cc6e5d1.eli  ONLINE
root@freenas:~ # zpool status HDD
cannot open 'HDD': no such pool

I attempted a force mount based on another forum using:

Code:

root@freenas:~ # zpool import -fFX HDD
cannot import 'HDD': one or more devices is currently unavailable

What I don't understand (Other than this being my fault) is how in mirror-0 both disks are online but it shows 'corrupted data.'
Mirror-1 only has 1 disk, as the other went removed, but the other disk shows online but the mirror is again corrupted.
Also, all the disks are online as far as I can tell:

Code:

root@freenas:~ # glabel status
									  Name  Status  Components
gptid/723ae9a4-2c13-11e8-85a9-408d5cc6e5d1	 N/A  da0p1
gptid/a8cfb85d-fad0-11e6-9551-408d5cc6e5d1	 N/A  ada0p2
gptid/a2eb439b-19c9-11e7-9e0f-408d5cc6e5d1	 N/A  ada1p2
gptid/ddf1c8e2-76d7-11e8-b59d-408d5cc6e5d1	 N/A  ada2p2
gptid/b7d0542d-d4c2-11e7-951c-408d5cc6e5d1	 N/A  ada3p2

ada0-3 are the disks in this particular pool.
These disks are encrypted (Beginning in FreeNAS 11 it has not been too bad of an experience), but that is not an issue. My recovery key unlocks the drives.
I do not have a backup (Future aspiration) and the data is not critical (In the sense I am not losing money), however it would probably take a week to recover from this and ~8TB would need to be recovered, so I would like to avoid that if possible.

EDIT: Silly me. I did not include the hardware information. I knew I would forget something.

FreeNAS Build: FreeNAS-11.1-U5
Motherboard: Gigabyte GA-B150M-DS3H
CPU: Intel Celeron G3900
RAM: 32GB DDR4 (8 by 4) (32610MB)
HDDs: 4x 6TB WD Red Pros (In this specific pool) RAID 0 + 1
Motherboard SATA controller is in use.
iSCSI: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller
Fibre: QLogic Corp. ISP2432-based 4Gb Fibre Channel to PCI Express HBA

I can provide any additional information as requested. I did not think of anything else to gather initially. I greatly appreciate any help. This is also my first ever forum post on the internet, so go easy!

Please read and follow the Forum Rules and post the information (you can edit your original post) the rules
ask for. Thanks, and good luck!

Since your volume or pool is encrypted, you must follow the steps
in the User Guide for replacing an encrypted drive.
You must have a drive to replace the one that is failed, just unplugging and
reinstalling the same drive is NOT going to return your pool to a healthy status.

If the GUI will no longer show your drives so that you can offline the "unavailable" drive
and resilver a replacement, I'm not sure your data is recoverable.

Maybe someone else has other ideas but this is as much help as I can give. Good luck!!!

The pool is detached, so there is no way (That I am aware of) to replace the 'failed' drive.

Looks like it is time to start the grieving and rebuilding process.

Thanks!
