Unraid reboots doing parity check on bigger drive. Help please?

[mattw]

So, I shutdown my server, pulled my 2tb parity drive, installed 4tb precleared drive, booted server, assigned drive, ran new config because it refused to start the array.  All drives mapped properly parity rebuild started and the machine rebooted several minutes into the check.  So far, I have gotten to 24% before it rebooted the last time.  Nothing is reporting to much heat, no drive errors and no indicator of a problem.  I do have my old parity drive untouched and should be able to go back to it if I wanted to, but I really want to use larger drives to replace some really old 1.5tb drives.  I have also stopped all but 2 of my docker containers after the last reboot.  It almost feels like something is happening when my screen on the pc I am working from times out and goes to sleep.  The CPU and motherboard are really old, maybe it has a problem with 4tb drives?  But, it did not have a problem with doing a preclear on the drive.  BTW, working with Microsoft Edge as Firefox seemed to give me some issues and I seem to remember that there was some problem doing this kind of stuff in Firefox.  I did not remember this until the first reboot was intentionally done.

 

I am attaching the last 2 diag files for your viewing pleasures.

Are you sure your PSU and the power cabling is up to handling this?  Doing a parity check is normally when there is likely to be most power being used and even a temporary voltage dop can cause problems.

Pls also run memtest, your system show some odd reading, configured in 1280MT/s or 257MT/s.

 

My system show FYR.

So... I think you are on to something.  This mobo is pretty old and it appears that I have to set the performance options for each stick!  Has been more stable now.  I also removed the Kingston ram as it was only 4gb sticks and they were not a brand match for the others.
