It means you have the worst issue possible, a system you can't trust. Keep in mind ALL data that you read and write to the server flows through that RAM, so until you can have confidence in it again, consider all files possibly corrupt.

 

Good thing this is a brand new build and I don't have any files on there yet!

It means it is going to be harder to troubleshoot, but troubleshoot you must.All of your servers data and instructions goes through memory. If memory is unreliable everything is.

 

Yeah, ran it again overnight and there are a few thousand errors again. I'm just going to send this RAM back and get a new set. I'll run memtest right away on the new set.

Any memory errors at all are unacceptable. Try running test with only one module at a time, try running test with module in different slots, etc to isolate the problem.

So, what does it mean if I run the test once and get a lot of errors, but run it again (exactly the same way, both sticks, nothing has changed) and get none? It just went through all 4 passes with no errors at all.

Yes. Sorry was on my mobile before.

 

I had bad RAM cause this myself. I think others did too. But there was also an issue with the plugin, don't know if it was resolved.Anyway memtest can't hurt.

 

Thanks. I've been running it and it's already thrown up thousands of errors. So you're probably right.

Memtest on boot menu

Is this for me? So this could be a RAM issue?

Hello,

 

This is my first time using unRAID and I'd call myself moderately (or semi-moderately) computer-savvy. I've been following the instructions from Space Invader's videos and started preclearing my 2 8TB Seagate Ironwolf drives yesterday. Everything was going fine, until the post-read, when after about an hour each into the post-read they both failed, with this message from both: "Post-Read verification failed - Aborted". Here's the log from one of them:

--> FAIL: Post-Read verification failed. Your drive is not zeroed.

 

I think I've read in here that this may just be an error with the plugin? If so, am I good to go on these drives? Or what should I do instead? I'm running version 6.5.2 and the plugin is from 2018.05.03. Thank you for your help.
