Hello everyone! I may be having a very edge-casey issue. I tried setting up k3s on Asahi Linux on an M1 Mac for the fun of it, and I seem to be getting the following issue across the board:

Failed to create pod sandbox: rpc error: code = Unknown desc = failed to get sandbox image "rancher/mirrored-pause:3.6": failed to pull image "rancher/mirrored-pause:3.6": failed to pull and unpack image "<http://docker.io/rancher/mirrored-pause:3.6|docker.io/rancher/mirrored-pause:3.6>": failed to extract layer sha256:c640e628658788773e4478ae837822c9bc7db5b512442f54286a98ad50f88fd4: mount callback failed on /var/lib/rancher/k3s/agent/containerd/tmpmounts/containerd-mount3367908043: signal: segmentation fault: : unknown

Segmentation fault always seems like there is quite something going wrong, and I couldn't find anything related to this when googling (additionally, I have no idea what I'm doing when it comes to k8s), so I thought maybe you people can give me some guidance here. Or is this more of an issue with containerd itself?

This sounds like https://github.com/k3s-io/k3s/issues/6708

This was the closest issue I could find as well. However, running

getconf PAGESIZE

returns

16384

for me, but it's certainly not 4k. On the Asahi project page it says "The Asahi Linux kernel is compiled to use 16K pages. This both performs better, and is required with our kernel branch right now in order to work properly with the M1’s IOMMUs. Unfortunately, some Linux software has problems running with 16K pages", so yeah, that's probably it... I take it there's not much I can do about it then?

ah yeah. anything not 4k will blow up.

I think it's possible to get it to work on Asahi as well. I may give this a try. Would this mean that I am restricted to running all my containers on amd64 as well? If so, this would be a big hit on performance

well, some number of the binaries in arm64 container images will probably crash for the same reason. Most stuff expects a 4k page size since that’s the standard for most distros.

dang, that's a bummer. Looks like Linux on Apple Silicon still has some ways to go. Thanks for the quick help though! Much appreciated
