hawihoney Posted January 10, 2019 Share Posted January 10, 2019 During a parity check on a dual parity system the follwing errors popped up in syslog 64 times. I can see that in the error column of the main page. SMART shows one pending sector to remap. But Unraid stiil runs the parity check. What does that mean? Are these errors fixed? Sure I will replace that drive, but I'm curious what's the meaning of that. Thanks.

JorgeB Posted January 10, 2019 Share Posted January 10, 2019 According to that snippet you're doing a rebuild, not a parity check, "multiple disk errors" means you are beyond current redundancy, though if you have dual parity you shouldn't be, please post the diagnostics: Tools -> Diagnostics Quote Link to comment
