What Happened?

Attempting to mount a local user folder from my Fedora 37 VM into the minikube container with:

minikube --alsologtostderr mount /home/steve/dev/k/localstack/ready.d:/ready.d

Results in

mount: /ready.d: mount(2) system call failed: Bad address.

Having the exact same issue on Fedora 37. Doesn't matter which driver etc I use

afbjorklund commented 1 year ago

Seems something is different between Fedora and Ubuntu

afbjorklund commented 1 year ago

One thing to try would be a different --mount-9p-version

Like 9p2000.u (it was upgraded to 9p2000.L in #https://github.com/kubernetes/minikube/pull/3796)

Hi, I tried with version 9p2000.u but got the same result

pjnssn commented 1 year ago

I just tried running Fedora 36 in a VM and with that mounting works, so something that changed between Fedora 36 -> 37 seems to be causing the issue

afbjorklund commented 1 year ago

Probably some kernel change in Fedora then, that affected the 9p filesystem... Since the docker-in-docker driver inherits the kernel, it is doing the mount.

EDIT: I think it did a massive upgrade, from Linux 5 to Linux 6.

afbjorklund commented 1 year ago

All protocol errors (read/write) seem to be returning EFAULT, so I guess that the underlying error could be anything regarding the 9p transport ?

Ended up going back to Fedora 36 as a short term solution for myself.

Even with the 6.1.15 kernel (6.1.15-100.fc36.x86_64) it works on F36. I don't see any other thing it could be than something related to 9p since the troubleshooting I did when I was still on F37 involved using different drivers for minikube (docker and kvm2) and even testing the underlying file systems (different docker drivers as well as completely different filesystems, both BTRFS and EXT4 with and without LUKS) and none of them worked on F37.

Edit: Oh and when running 'minikube start --mount' it works and correct me if Im wrong but that uses a different method than 9p as done with 'minikube mount'

pjnssn commented 1 year ago

Seems to be working now with minikube 1.30.0 and 1.30.1 with Fedora 37

sshort commented 1 year ago

I can confirm that this works for me with minikube 1.30.1 on Fedora 37.
