UnraidDisplayName Posted January 13, 2021 Share Posted January 13, 2021 (edited) a couple of weeks ago my server started shutting down when put under a load. it did this maybe 4 times and after that i left it off and purchased a new power supply, assuming that my power supply (~5 years old) was biting the dust. new power supply arrived, plugged it in, and.. nothing. back and forth troubleshooting of port/cable combinations i found that replacing the fan controller 6-pin molex power cable allowed everything to power back up as normal. i am now powered back up, and logged into the server, but for some reason unraid doesn't see two of my hdds. slots 1 and 4, if it makes a difference. i've reviewed the logs and found that unraid logs sata link down for these two items, but i have no idea why? it's been running fine for several years, so i can't imagine it's a setting that suddenly needs to be adjusted or tweaked. i'm wondering if it wasn't the cable that was faulty and maybe a port on the motherboard? dunno, honestly just guessing...i'm hoping that someone can assist with a log review and point me in a direction. i've reviewed the logs myself, but other than the link down info, i'm not sure what's abnormal vs. standard. logs attached. thx in advance for any assistance. media-diagnostics-20210113-0035.zip Edited January 16, 2021 by UnraidDisplayName Quote Link to comment
trurl Posted January 13, 2021 Share Posted January 13, 2021 You mention troubleshooting port/cable combinations before you got your power working, but have you tried swapping ports after you got your power working? Quote Link to comment

JonathanM Posted January 13, 2021 Share Posted January 13, 2021 Did you, by any chance, replace a modular power supply with another one? If so, did you switch ALL the cables to the new ones? Just because the old modular cables fit, doesn't mean they are compatible. Running with the wrong cables for even a second or two can burn up drives. Quote Link to comment

Possibly with all the drives connected, the PSU overcurrent protection kicked in before it fried anything, but with only a couple plugged in the PSU fired up and appeared to work while frying the 2 remaining drives?

Your paraphrase of those instructions is vague enough to be disastrously misleading. Just thought I would mention that in case someone else sees this thread. Also, here is a more up-to-date link: https://wiki.unraid.net/UnRAID_6/Storage_Management#Replacing_disks Unfortunately, since you didn't have dual parity you can't rebuild anything with 2 missing disks.
