Hi everyone,

Sorry if there is another similar post but I couldn't find it with search.

I am using unraid for 1 year and I am very satisfied and without any problems until today. Every 1st day of every month I have scheduled a parity check without any errors until now. Today parity check give me 593 errors and I don't know what to do.

My data seems to be ok and all the services is working ok.

Does anyone have any advice what to do?

I haven't made the latest update v6.3.3 and I am running v6.3.2 because this will restart the system.

Looks to me like the errors were caused by the SAS2LP timing out, you're not the first, notice that they started exactly 60 seconds before the SAS2LP error:

Look for a bios update, If you have vt-d enable and don't need it disable it, try a different pcie slot if available and run another check, if errors persist consider replacing the controller.

Thanks for the quick reply. I think that my cpu G620 doesn't support VT-d but only VT-x. I will check it out.

 

I think that most likely to be the controller, now that you mention it, despite the Bios. Because for one year does not show any problems and I have not changed any settings.

 

Is there a case to blame the power supply;

You are right. There was a BIOS update and I've done it. It says that was for "Enhance compatibility with some PCIE devices.

I will run Parity check again and we will see.

Thanks again.

Hope it helps, and although only a few SASLP/SAS2LP users have those issues, it's a fairly common problem.

You were right. The problem was the controller. I replaced it with Dell PERC H310 0HV52W  and flash it in IT mode and parity check errors dissapeared.

Thanks again.
