I have been using Unraid for many years now, but just recently started to have very slow parity check last few times. I had to cancel each time. Hope experts here can help me resolve this. Diagnose zip has been attached while the parity was still going on. Image attached of the parity speed.

 

Disk details below:
Parity: Seagate Exos Mach 2 14TB(Parity) - 7200rpm
Disk 1: Seagate BarraCuda Pro 10TB - 7200rpm
Disk 2: Western Digital Blue 6TB - 5400rpm
Disk 3: Western Digital Blue 6TB - 5400rpm
Disk 4: Toshiba 3TB - 7200 RPM
Disk 5: Western Digital Blue 8TB - 5400rpm
Disk 6: Seagate IronWolf Pro NAS 10TB - 7200
Disk 7: WD BLACK SN750 NVMe SSD 1TB (Cache)
Disk 8: Toshiba 3TB - 7200 RPM (Unassigned Device Disk)

 

Server Specs:
Mobo: ASUS PRIME Z390-A
CPU: Intel i5-9400 CPU @ 2.90GHz
Memory: 32 GiB DDR4

 

I have been running this exact setup since day one. only change is that Disk6 used to be Parity. 14TB Parity is recently added and even after this addition, parity checks were running fine. Parity was upgraded last year.

 

 

Thank you.

Unraid driver is crashing, this is almost always a hardware problem, since you have multiple RAM sticks, try again with just one, if the same try with the other one, that will basically rule out bad RAM.
