unexplained reboots for my frankenstein baby

[slowpoke]

As with many others; I have a cobbled together unraid server from parts discarded by family members, despite the unceremonious origins; it has become my baby, my pride and joy and for the last 5 years has been flawless. Out of the blue i get an ungracefull shutdown; restart, auto mount, forced parity check and then the cycle starts again. partiy check gets 11 or so mins in each time. 

with or without the disks mounted,(all docker services stopped) it will happily sit there. untill i go to manually start a parity check. 

having read through a few different support tickets, the common thread seems to be hardware issues. ive swapped out the mismatched dinosaur ram, for some matched dinosaur ram; i have coerced another unloved pc from my boss, but short of swapping everything out like the ship of Theseus. i would like to see if anyone can decipher the syslog and/or diagnostic report. 

 

  as far as the syslog goes; the server was sitting with drives unmounted for 3 days; line 8699 is aprox. where I mount the drives; and go to run parity check then it reboots.

 

appreciate any help i can get. (and please explain like im 5; the entirety of this is based on the dulcet tones and handholding from spaceinvaders youtube)

There's nothing relevant logged, suggesting a hardware issue, the same if it starting doing this recently without any changes, start with whatever is easier for you to try, like running memtest, trying a different PSU, etc.

If starting a parity check causes a problem then I would be suspicious of the PSU as that is when it is likely to be under maximum load.   Do you have another one you could try?

[slowpoke]

Yeah i suspected as much;

I appreciate your time looking at the logs. Thank you.

I'll mark this as solved and update RE which component failed me.
