Description Martin Pitt 2019-11-18 07:42:05 UTC

Description of problem: I upgraded my F31 OSTree host system yesterday, and now toolbox is broken again:

$ toolbox create
Created container: fedora-toolbox-31
Enter with: toolbox enter

$ toolbox --verbose enter
toolbox: running as real user ID 1000
toolbox: resolved absolute path for /bin/toolbox to /usr/bin/toolbox
toolbox: checking if /etc/subgid and /etc/subuid have entries for user martin
toolbox: TOOLBOX_PATH is /usr/bin/toolbox
toolbox: running on a cgroups v2 host
toolbox: current Podman version is 1.6.2
toolbox: migration not needed: Podman version 1.6.2 is unchanged
toolbox: Fedora generational core is f31
toolbox: base image is fedora-toolbox:31
toolbox: container is fedora-toolbox-31
toolbox: checking if container fedora-toolbox-31 exists
toolbox: calling org.freedesktop.Flatpak.SessionHelper.RequestSession
toolbox: starting container fedora-toolbox-31
toolbox: /etc/profile.d/toolbox.sh already mounted in container fedora-toolbox-31
Error: unable to start container "fedora-toolbox-31": creating file '/var/home/martin/.local/share/containers/storage/overlay/d981f538fd1de6f6b79894fcb94b7352e293a9f2ba01b2ed9363e4635e664746/merged/mnt': Is a directory: OCI runtime error
toolbox: failed to start container fedora-toolbox-31

This error comes from podman:

$ podman  start fedora-toolbox-31
Error: unable to start container "fedora-toolbox-31": creating file '/var/home/martin/.local/share/containers/storage/overlay/d981f538fd1de6f6b79894fcb94b7352e293a9f2ba01b2ed9363e4635e664746/merged/mnt': Is a directory: OCI runtime error

So the problem is apparently in the way the container gets set up, most likely the bind mounts:

            {
                "Type": "bind",
                "Name": "",
                "Source": "/mnt",
                "Destination": "/mnt",
                "Driver": "",
                "Mode": "",
                "Options": [
                    "rbind"
                ],
                "RW": true,
                "Propagation": "rslave"
            },


A simple podman invocation without volumes still works:

$ podman run -it --rm registry.fedoraproject.org/f31/fedora-toolbox:31 /bin/bash

But it reproduces with a volume:


$ podman run -it --rm -v /mnt:/mnt:rw registry.fedoraproject.org/f31/fedora-toolbox:31 /bin/bash
Error: creating file '/var/home/martin/.local/share/containers/storage/overlay/5ba39ba24e32611acef21e4d93d845169cb8d70096b817382630ec5747c4c4a5/merged/mnt': Is a directory: OCI runtime error

toolbox uses flags ":rw,rslave", but that fails just the same way.


Version-Release number of selected component (if applicable):

podman-1.6.2-2.fc31.x86_64
toolbox-0.0.16-1.fc31.noarch
kernel-5.3.11-300.fc31.x86_64


How reproducible: Always


Additional info:

Neither podman nor toolbox got upgraded in the last run, the only relevant package seems to be the kernel:

Comment 1 Martin Pitt 2019-11-18 08:49:28 UTC

Argh, I was missing the updated "crun" package (I was looking for "runc"). So this is https://github.com/containers/toolbox/issues/330 and it already got fixed in https://github.com/containers/crun/pull/178; but there's no bodhi update for it yet, apparently.
