Recently my unRAID server started showing parity errors, so I replaced a drive that had some smart errors.  I thought this would fix it, and it did show 0 errors after install, but the parity errors are back.

 

I see a new drive has SMART issues - Reallocated sector count of 8.

That number isn't increasing, at least since I noticed it, and from what I have read, this is a normal thing for modern drives?

 

Any help would be greatly appreciated.

 

I'm running unRAID 6.8.3
Plugins:
Community Apps
Fix Common Problems
Unassigned Devices, Plus
User Scripts

 

And a Plex docker.

 

Thank you!

Start by running memtest.

Thanks, made it through 1 pass with no errors.  I'll let it run overnight.

68 hours and 31 passes later, still 0 errors on the memory, so that seems to be ok.

 

Does anyone have any idea why I keep getting parity errors?

 

Thanks.

 

If it's not RAM it can be a controller or even a hard drive, unfortunately no easy way to test except rule out one thing at a time.
