February 10, 201610 yr Hello Im totally new here and I came across UnRaid from an LTT video and thought I should try it out on my old old Intel i3 "server" All seems to work, but the problems I have is that the array shuts down, server gets unresponsive at random. So far I have just 1HDD, an older WDgreen 2TB. Gets warning that the disk is too hot, 45C and I wonder if this can be the reason. The server also has 2Intel NICs, one PCI-E and one PCI that seems to not been detected, so using the integrated nic. Edit: Heard someone say that the array gets auto-off if the disks gets too hot, but can't find it in the documentation.
February 17, 201610 yr Author Seems like I found out of it, checked a lot of settings and for some reason the CPU was under clocked. rested it back to normal settings and now it has been stable for 2 days
February 21, 201610 yr Author Nope, it was stabel for some time, but after I put in another hdd it crashes after some time when trying to clean the drive. Got some logs this time. gumi-server-diagnostics-20160221-2238.zip
February 22, 201610 yr Community Expert Let's make all of the simple checks first. Are all of the fans spinning? especially the CPU fan. Are all the case fans blowing out? If you have any fan(s) blowing in, is it in the front of the case blowing into the hard drives? Sometimes there are fans in the side of the case blowing but these are usually intended to high power GPU card and you should need one of these in most unRAID servers. You want the air flow to come in the front of the case to cool the drives first and exit out the rear of the case. Have you run memtst (available from the boot menu as the server is booting) for at least twelve to twenty-four hours?
February 22, 201610 yr Author All fans are working. Im using an Node 804 case, has not modified the fans so the one in the cpu part of the case blows out and the other on the back of the motherboard, where the harddrives are blows in, onto the disks. I ran memtest for 2-3hours earlier and an hdd check for 6hours without any crashes.
February 22, 201610 yr in the summer last year we got a heat wave here in LA and 12 of my drives would run at 45C all day they would cool down to 35 overnight but back at it again the next day this went on for a couple of months until heat died off my system had no problems throughout right now its winter and all my drives are at 20-25C which is relieving lol hows the power supply?? and how old is the system?? have you tried new thermal pasts on the cpu?? usually if the cpu gets too hott its when the system locks up and shuts down
February 22, 201610 yr Author ops, forgot to mention that. Its an older system I have used for a lot of things, the cpu is an i3-530, so first gen i-core, so pretty old. Have never changed the paste on it, mabe time to check and redo that. Power is an older cooler master 600W. The same system used to run PFsense none stop for over a year without any problems, but that may not use as much cpu ether.
