RaspberryPi becoming unresponsive at random intervals (lemmy.world)

Issue Description: I have been having this issue with my raspberry pi running dietPi where it seems to lock up and I cannot SSH / access any of the services on it. The interesting part is that the interface seems to be up and I can still ping it on the local network but shows no video output. usually I get about 3-6 days before the issue appears again.

I am not really sure where to start to diagnose this issue. Any help would be appreciated!

Things Tried:

Reduced operating temp by getting a fan. I want to say this improved the length in between this issue appearing but don't really have any hard evidence.

uninstalled unused services

Limited active torrents in QbitTorrent

EDIT: Small thing to mention is that the CPU load is usually really high - like not uncommon for the load to be between 8-10 but I have seen it as high as 24.

Temporary fix:

Power cycle - everything comes up again in less than a minute.

Raspberry Pi 3B v2

OS: DietPi

Services:

Lidarr

Radarr

Sonarr

Prowlarr

Qbittorrent

Mullvad VPN - WireGaurd

SSH

I’d bet $1 it’s the SD card. My 3B+ used to have the same problem. Been running pis off some sort of SSD ever since, no issues.

Pi 3B has dedicated bus for SD card but ethernet and usb share bandwidth. Enable zram, disable all swap and keep using sd card.

@a_fancy_kiwi I agree, same here. This is the last pi that's running off an SD card with services that do "significant" disk I/O. I have a few zeros that only really write to the card for OS updates. Their job is to collect data and send it via the network. I haven't had issues with that kind of workload using micro SD cards.

Edit: For Pis with write workloads I'm using basic USB3 SSDs. Didn't have good results with USB sticks though.

Id be willing to try this. How do you have it connected? Just using an external USB attached one?

[–] a_fancy_kiwi@lemmy.world 1 points 10 months ago* (last edited 10 months ago) (1 children)

I upgraded to the Pi4 but I use this case. It has a daughter board that lets me use an m.2 SATA SSD over USB. But any USB to SATA adapter should work fine

You should get a scsi enabled adapter though, otherwise you may have to disable it in the kernel boot settings. And if you forget that it will run at like kbit/s.
