Hello,

 

Last night as part of a scheduled parity check, my Unraid server detected some errors.

It asked me to download Nerdpack plugin and post the the logs here.

Your server has detected hardware errors. You should install mcelog via the NerdPack plugin, post your diagnostics and ask for assistance on the unRaid forums. The output of mcelog (if installed) has been logged

 

I didn't download the plugin, however I did go to Tools > Diagnostics and downloaded all the logs, which I am attaching with this post.

Can someone please take a look and point me in the right direction of how to go about troubleshooting this machine error?

 

Thanks in advance!

Stay safe at home!

Do you have any other symptoms?

Hi there,

 

Other than that warning, none in particular. No slowness or erratic behavior, if that's what you're hinting at.

Your syslog shows: 

 

Apr  2 03:46:24 Stacker kernel: mce: [Hardware Error]: Machine check events logged
Apr  2 03:46:24 Stacker kernel: EDAC MC0: 1 CE error on CPU#0Channel#1_DIMM#0 (channel:1 slot:0 page:0x0 offset:0x0 grain:8 syndrome:0x0)
 

Looks like there is an issue with one of the sticks of your memory. If it's ECC memory, you should be fine so long as you're not seeing a large amount of errors appear. You can run memtest86 if you want to test things.

Thanks! I can definitely try that.

It is ECC. I have a Supermicro NAS chassis, but you are right in that I have to run the memtest.

 

Thanks for pointing that out!

Really appreciate it!

Memtest won't detect ECC errors, since they are corrected, check the board's SEL (system even log), it might have more info on which is the problem DIMM.
