I have a pool of two 4TB Seagate Ironwolf hard drives (same batch). The pool is set up to mirror across the drives and both showing the status of ‘degraded’. I’ve run S.M.A.R.T tests which highlighted no errors.
The only difference between these two drives and the others in my NAS is I’m using a PCIe SATA card with them. Not sure if that’s relevant or a contributing factor, but I thought I’d mention it.
I’ve tried scrubbing the pool twice as I could see others have had success doing this, but the number of errors increased after each.
Do I have two bad disks here or is there something else I could try before replicating the pool and sending the disks back? Any help or suggestions here would be very helpful.
Hey there. Thanks for the reply. Here’s the output for Storage3, my problem pool:
pool: Storage3

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.

Thanks for getting back much appreciated. I’ve put an order in for a new SATA controller and I’ll switch out the cables too and let you know how I get on
Thanks. I’ve ordered a SAS2008 card, it seems there’s quite a lot of documented steps for flashing it to IT mode. All being well, everything should be here tomorrow
