Interesting… I’ve used 2 different CPUs in this system over the years and the crashing has been across both - so it’s probably not that. I think I’ve also swapped ram at some point, but that’s easy so I’ll just re-seat it to bu sure. I don’t think I’ve ever touched the GPU so maybe re-seating it & the riser would help. Worth a try, at least. Thanks!
It’s a SFF case so I can only use SFX psu instead of normal sized ones. That limits my options a lot, but I’ll see if I can’t find a bigger one.
Interesting, it’s a bit hard to test as the crashes are super un-reproducable. (I don’t think I’ve ever been able to produce a crash with a synthetic benchmark or the like). Any recommendations for testing? Or do I just have to run the system for a while in each state and keep track myself?
Yeah. I’ve been desperately avoiding trying the GPU directly in the slot since the whole thing is water cooled w/ a custom loop and I don’t want to drain & re-plumb it. I might have to though, ugh. Next PC I build is going to be 100% air cooled haha
Yeah I was kind of thinking that too, but I don’t have evidence to back it up! Anyway, I’ll look around and see if there are issues with this model
It’s about 4 years old, so not new but not crazy old. I’m also in a SFF case so I’m using a PCIE riser, which could also be the issue. Do you know, is there a way to tell if it’s the riser or the PSU? I can run memtest to check the memory.
I imagine it’s getting enough airflow. It’s a sff case, but the fans blow right over the PSU so it’s probably fine… Would there be a way to tell if it’s overheating?
Do you think 750W would cut it? Corsair makes a 750W version of the PSU I’m using so it would be an easy drop-in replacement
Yeah seems like a good move, Corsair makes a 750W version of this PSU that’s comparable with the same cables - so I could swap without even having to re-do my cable runs! Seems like it’s worth a try. Hopefully I can get it somewhere local though, as I hate returning stuff in the mail. Thanks!
You could try getting a Chromebook and installing whatever distro you want on there? I know it doesn’t avoid the pre-installed spyware, but at least it’s free so you’re not loosing money paying for a license. And Chromebooks these days are made in a wide range from very inexpensive to sorta-premium.
I would, and I plan to someday, but my whole storage system is setup on it and migrating would be an enormous pain. Also right now I rely on it’s ability to create a RAID array with differently sized drives. Next time I upgrade, I plan go get homogeneous drives, so maybe then would be the time to move away from Unraid.
Oh interesting, that sound plausible. I’ll check out the bios and see if I can find that setting. Thanks!
It’s not that easy sadly. The entire NAS runs on Unraid and the issue is with that OS. I can’t switch without totally restarting from scratch which would be a huge data migration, and a massive PITA configuration-wise.
Eventually I’d be open to switching to something like TrueNas Scale, but for now I need Unraid’s unique ability to run a RAID array with differently sized drives
I specifically had to set things up in the BIOS so that it would never enter any efficient power/sleep states. It’s a bug in the OS I’m using that was forcing me to do it, otherwise the whole thing would lock up on me.
That said, I have some smart-plugs that do power monitoring. I can try hooking up the nas to one of those just for kicks, it should be accurate enough for this sort of thing.
Edit: Just measured and looks like I was about right: 100W under load and around 80W idle
I have the nas connected to a UPS that reports it’s power draw and it sits at about 100W at all times. There are one or two other small devices connected to it usually, so the nas itself is probably using a hair less that that at idle, but still it’s quite high.
That’s an interesting issue. Do you think the problem would be the same for any CSI plugin? I’m thinking of using my NAS as the storage brains of the operation and hooking it up with NFS or something, but would that have issues with stateful stuff like DB’s too?
This is awesome, ZeroToNix is exactly what I was looking for. I’ve been interested in trying NixOS for a while but I always found the documentation obtuse (extensive, which is great, but not super beginner friendly). I’ll give it a try!
This seems like a sensible choice, but it would be a bit messy for multi-node which is the direction I’m heading in
Thanks for this, I’ve been sort if interested in both Nomad and NixOS for the exact reasons it seems like you use them. Thanks for linking that repo, I’ll check it out for inspiration!
Do you find that you sometimes struggle to get things working in Nomad? My one worry is that, because it’s not as well established as kubernetes or docker, there won’t be good compatibility or documentation. For example most services in their docs will show how to deploy with kubernetes or docker, but rarely Nomad. Do you find that it’s easy enough to translate these instructions that it doesn’t matter?
I mean I think it really depends on the type of website you’re trying to host. A static blog would use way less bandwidth than a media server for example. Traffic would have the same effect too, where 1 concurrent visitor to a blog would probably be fine but 10,000 would be a problem.
It’s a water-cooled SFF build so thermals can be an issue. Maybe somewhere something is getting too hot, it’s a decent theory. I’ll try building up a bunch of heat in the case to see if that increases instability. Thanks!
