sonic6 Posted June 3, 2021 Share Posted June 3, 2021 Hello, i got some "dma crc error count" and then my Parity Drive was disabled. The only thing i did, is disconnecting an 2TB Unassigned Disc and changed it against a 4TB one on the same port. Then started the backups script from this thread: Diagnostic is attached. Is there a way to bring my Parity Drive back online, without using "new config"? I hope, you can help me. Thank you. unraid-1-diagnostics-20210603-2003.zip Quote Link to comment

CRC errors are usually caused by defective cabling and/or controllers. How is the parity drive connected? Possible to swap the cable? 1 Quote Link to comment

Parity Drive is connected to an HBA: IBM ServeRaid M1015 SATA / SAS HBA Controller (IT Mode) with a Mini SAS 36 Pin-Stecker (SFF-8087) to 4 x SATA i can swap from P00 to P01 on the HBA when i installed this, i was very carefully and this worked since february what is the best way, to bring my parity back online?

From my understanding, Unraid only disables a drive when it cannot write to it. So, if it was disabled, the content of your Parity drive is probably out of sync with the Array. You could do a new config and say that Parity is valid, but it is probably not. Let's see what our more experienced users think of that. 1 Quote Link to comment

JonathanM Posted June 3, 2021 Share Posted June 3, 2021 Start the array without the parity drive assigned, stop the array, assign the parity drive and let it build. 1 Quote Link to comment

I was not afraid of data drives content, only of Parity rebuilt. jonathanm's answer match what I was expecting. Quote Link to comment

I had a similar cable from CableCreation with a loose contact. Maybe you better try a cable from Supermicro (if they have this cable type). Quote Link to comment
sonic6 Posted June 3, 2021 Author Share Posted June 3, 2021 Yes. I habe a DS380 Case with hot-swap cages. I didn't touched that drive for month. Quote Link to comment
