Truenas Core Pool Offline

[Jamesr98]

Hi guys,

 

I recently built the same Truenas Core as Linus did during this video: 

I put in 5xSeagate IronWolf 10TB NAS Internal Hard Drive HDD: https://www.amazon.com.au/gp/product/B085ZB51HW/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1

I configured my pool using raidz1 for 1 drive worth of redundancy.

It was working great up until last night.

My pool went offline. I did a manual SMART test on each of the drives and they all returned successful results.

So I tried to export and re-import my pool. The export worked, but now when I try and import the pool, I get an IO error

Error: concurrent.futures.process._RemoteTraceback:

The above exception was the direct cause of the following exception:

My complete system specs are:

MotherBoard: Asus B550-I M

CPU: Ryzen 3100 (using stock cooler)

Memory: G-Skill 16Gb 3600MHz

Power Supply: Corsair SF 600

Hard Drives: 5x Seagate IronWolf 10TB NAS Internal Hard Drive HDD

SSD: Kingstone 250GB

Case: JonsboN1

OS: TrueNAS-12.0-U8

 

I am using this NAS for Plex, File Storage, and a DDNS Server.

Can anyone please help me. I have done the cardinal sin of not having offsite backups as it wasn't in my budget yet.

 

Thanks,

James.

You may have better luck in the official TrueNAS forums, however they're less friendly over there.

Thank you @HeroRareheart.

 

I will post there as well.
