Hi 

 

First post on the forum and the first issue I've encountered since installing unRaid a few months back. Someone accidentally unplugged my server and I've powered it up and away I went however I noticed a Warning telling me the Parity check had run and found 84407557 Errors. I've Googled the Warning and can see that others have also had the issue but reporting MUCH LOWER Parity Errors which makes me think of what impending doom awaits? 

 

My Set up is a HP Microserver n40l with WD Red 4TB Parity and 3 x Seagate 1TB disks. 

 

So in your opinion am I worrying over nothing or is something about to go bang? S.M.A.R.T and Parity shows Green across all disks. Am I able to determine whether this was isolated to a single disk which would indicate a failure is due? 

 

Any advice would be great at this stage as I'm still a bit of a newbie and dipping my toes into running a NAS on unRaid/Linux, I shifted away from a Windows Home Server build. 

 

Cheers

Probably your parity wasn't valid but can only speculate what you may have done to get to that point. 

 

You could post Diagnostics but might not tell us much. 

Sorry for the brevity of my previous reply but I was on mobile. Since nobody followed it up I will.

 

Go to Tools - Diagnostics and attach the complete diagnostics zip file to your next post.

 

The only acceptable result for a parity check is exactly zero. Anything else needs to be corrected and then rechecked. If you can't get it to zero then you likely have a hardware problem of some kind.

 

Many of us schedule monthly parity checks just to make sure things are OK. Had you done any successful parity checks before this happened?

 

Did you make any changes to disk assignments since the last successful parity check? Adding, removing, replacing, rearranging? If so, what changes did you make and how exactly did you make those changes?
