Paritydisk error state and a disk unmountable

[Tuinboon]

UNRAID V6.9.2

on a HP ProDesk 400 g4 Intel i3T

16 GB RAM

NVMe 128GB Cache

Data all on WD elements, WD MyBooks

Most important Docker: Plex

Important VM: Windows 10 (for the kids and their school stuff)

 

Hello unraid loving people,

 

My problems started when I wanted to swap disk 1 (SSD) for a WD Studio drive (for Mac) with the aim of adding the SSD as second cache drive. This resulted in the Studio not wanting to mount and after placing the SSD back in slot 1 a paritydisk in error. Tried different things following topics on forums but ended with Disk 5 unmountable and a paritydisk error state. I really believe I made a mess trying to fix things myself.

I checked and can’t find any real errors on both disks involved. Also my latest acquired movies stil play on Plex while I am pretty sure they must be on the latest added disk (Disk 5). 

Grateful for any help or tips!

Thanks in advance.

You should really avoid USB devices for array or pools, there are lots of disconnect errors on the log, reboot, start array and post new diags.

Thanks for your Reply JorgeB.

 

I tried reboot but it wouldn’t. Had to hard reset the HP. Than unplug all drives for it to be able to startup again.

Disk 5 did miraculously mounted and both Parity and Disk 5 have 0 read errors.

Remaining the problem of the Paritydisk in error state.

Thanks for helping me.

You can resync parity but like mentioned using USB drives you're likely to run into more issues in the near future.

I”ll resync parity and start saving for other equipment. 

Thanks a lot for your help and advice!
