Ohh OK, yeah that would be tricky unless you’re an EE

Most slicers allow you to mirror parts very easily

Damn, that is top-tier

Printing an enclosure now that will significantly improve the airflow

“sudo shutdown” gives you 60 seconds, “sudo shutdown now” does not, which is what I usually use. I’m thinking I could launch a script on startup that will check a pin every x seconds and run a shutdown command once it gets pulled low.

Printing the bracket for the drives in PLA now. I designed them to make minimal contact with the drives so I think they’ll be ok. Even in the rough draft setup the 140mm fan seems like overkill to keep them all cool. If the bracket warps I’ll reprint in something else. Polymaker recently released HT-PLA and HT-PLA-GF, which I’ve been eager to try.

I’ve got that covered. I got a filter for the big intake fan. Printing the first batch of enclosure parts now.

Nice. For the Pi5 running Pi OS, do you think using a GPIO pin to trigger a sudo shutdown command be graceful enough to prevent issues?

they could include a “mini UPS” to keep 12v/5v up long enough to shut down gracefully in a power loss scenario

That’s a fuckin great idea.

I’m in the same boat. Based on the things I’ve learned in the last hour or two, ZFS RAIDz1 is just newer and better. Someone told me that ZFS will help prevent bit rot, which is a concern for me, so I’m assuming ZFS RAIDz1 also does this, though I haven’t confirmed it yet. I’m designing my enclosure now and haven’t looked into that yet.

TIL. Looking into ZFS RAIDz1.

Good catch. I don’t have my USB-C cable coming from the buck convertor set up yet, waiting on some parts to arrive tomorrow. The USB-C power is currently coming from a separate power supply in this set up. Ultimately, there will be a single 12V barrel jack port to power the whole system.

That’s a super clean build, too bad he didn’t make a 5 drive version.

Awesome. It’s my understanding that ZFS can help prevent bit rot, so would ZFS RAIDz1 also do this?

I found this, it seems to show all the steps I would need to take to install RAIDz1: https://www.jeffgeerling.com/blog/2021/htgwa-create-zfs-raidz1-zpool-on-raspberry-pi

Ultimately I would love to use ZFS but I read that it’s difficult to expand/upgrade. Not familiar with ZFS RAIDz1 though, I’ll look into it. Thanks!

I build robots for a living, the power is fine, at least for a rough draft. I’ll clean everything up once the enclosure is set up. The 12V supply is 10A which is just about the limit of what a barrel jack can handle and the 5V buck is also 10A, which is about double what the Pi 5 power supply can provide.

Sick 🤘

Thanks, it’s why I’m here

which requires me to use revanced reddit now

Actually it doesn’t require you to do shit. You can just not use Reddit.

I also do not like having my volume or my AC set to an odd number…

Cool, now I can lose a whole gaming system
