Server hung up and lots of errors appeared

[lgb]

Hi there, today I was copying some files from my server when the computer just hung up. Never experienced something like this before (see image attached 'index').

 

After this, I rebooted the computer and unraid started correcting sectors. I have lots of errors (millions, see the image below) I suspect my files are OK and parity is wrong since all disk are almost new and there are no SMART issues. Maybe my memory bank is the problem but, how to check if file integrity is OK? In other words, could I check what files are incorrect? Most of them are photos so it would be easy for me.

 

 

Some logs:

Have you done memtest?

[lgb]

Hi @trurl

 

yes, I did it for 1 hour (2 complete test) and no errors so far. I must say that 2 weeks ago I did undervolt the processor to reduce the heat. I don't know if that's something I shouldn't have done. At the moment, I'm taking out all my files, just in case I get another error. Should I rebuild my parity or leave it untouched?

 

 

[trurl]

Are you sure you ever built parity to begin with?

[lgb]

Not totally. In that case, what should I do, start parity check again? Thanks

[trurl]

Can you start the array and post new diagnostics?

[lgb]

@trurlSure.

Looks like all disks are mounted.

 

Parity rebuild followed by new diagnostics.

Thanks @trurl I'll start right now.

 

Regards and thank you again.
