Parity check very slow (1.5Mb/s)

[vincentvriends]

After I updated my server to Unraid 6.12.6 my parity check is very slow. In the past the speed was around 100Mb/s, now it is only 1.5Mb/s, so the full parity check would take 200 days.

Does anyone knows how to fix this?

 

Attached my diagnostics file.

 

Thanks

Check/replace cables for disk1.

I changed the cables and it looks like that drive has no issues anymore, but now another drive is unmountable, so I'm first repairing that one to a new drive.

After the repair I will test the parity check again to see if the speed is higher.

 

Thanks for your help.
