hey boys and girls..

I'm in need of some assistance (diags attached) (please disregard the date - this happened right before x-mas, but I did not have more time to troubleshoot or ask your help, so I turned off the server and it's been off since)

• I bought 2 x 18TB disks (external then shucked) to swap with current parity drives (that were only 10's).

• Swapped out Parity 0 - did a re-sync and that just did it's thing, no problem

• Then when this was done, I was doing the same with Parity 1.

• Swapped out, and started the re-sync.

But after some hours (a little difficult to say, cause I'm was not glued to the screen) but maybe around 3-6ish hours, the server just does a reboot.

This screws up the rebuild/re-sync

I tried starting it again, same thing happens.

Tried a third time (this time with the window open (In the Nordics - hoping maybe a significant temperature-decrease would help).

it did not (and it was like 10-12C degrees in the room, so no overheating issue).

Any idea?

Is the drive fucked?

What troubleshooting I've tried:

I have swapped / changed the SATA-cable from the disk to the MB

I have moved the SATA-port used on the MB to different one (taking care not to use SATA that "could" be disabled due to M.2 drive (it is not, but making double-sure).

I have changed / added another power-cable from the modular PSU - dividing the disk's on 2 wires instead of everything on 1 (possible power-overload, again just to make sure).

Appreciate any help.

Server rebooting by itself is almost always a hardware issue; start here:

Not sure exactly what was the "correct solution".

But after checking the link and disabling C-states as well as a little bit of Curve-adjusting of the CPU, it is now working as intended (from my understanding).

No more reboots during Parity-sync/Rebuild and the server is now up and running and working again.

Thanks @JorgeB
