Of course I did it after system reset in both cases.
Please run this command AFTER running podman system reset

No overlay directories appeared under ~/.local/share/containers, only vfs* instead. When I run same buildah command as root, overlay* directories do appear under /var/lib/containers and no vfs ones. My debian is the latest one (sid) and it has the following fuse-related packages: ii fuse-overlayfs 1.9-1 amd64 implementation of overlay+shiftfs in FUSE for rootless containers ii fuse3 3.12.0-1 amd64 Filesystem in Userspace (3.x version) ii libfuse2:amd64 2.9.9-6 amd64 Filesystem in Userspace (library) ii libfuse3-3:amd64 3.12.0-1 amd64 Filesystem in Userspace (library) (3.x version) podman is 4.3.1 For both root and rootless configs podman system info reports runc runtime (runc_1.1.4+ds1-1+b1_amd64 package). Rgrds, Giuseppe any ideas?not sure why overlay or fuse-overlayfs are not picked. It would be helpful to open an upstream issue and attach the output of `podman --log-level debug ...` in addition to all the other information that is requested.On 03.01.2023 18:25, Daniel Walsh wrote: On 12/30/22 08:35, Михаил Иванов wrote: > You could do a podman system reset and then remove all contentfrom the storage with rm -rf ~/.local/share/containers To make sure there is nothing hidden there,But that's almost exactly what I did:I just purged the whole storage using podman system reset.

I assumed this has to be done in storage.conf but this file is not present anywhere at all. I have no idea why debian would be choosing VFS, unless this is an older version of debian and did not support rootless overaly. You could try installling fuse-overlayfs and doing another reset, then Podman info should show you using overlay with fuse-overlayfs.

I verified that ~/.local/share/containers became empty (only bolt database was still remaining using about 200Mb space) I have run 2 containers from docker.io: ibmcom/db2 and ibmcom/db2console. podman system df reports space usage by images 4Gb and by containers 6Mb. podman images command shows consistent values (two images, 2.83Gb + 1.21Gb) system df command shows that 32Gb is used on ~/.local/share/containers filesystem du shows that all this space is located under ~/.local/share/containers/storage/vfs/dir This directory contains 32 subdirs, 11 subdirs of 1.1Gb each, 6 subdirs of 2.6Gb each, rest subdirs take anywhere from 94Mb to 646Mb When I try to diff -rw for directories of same size, I see only reports for missing symlink files, but never real file differences. No real activity was performed with podman apart from running these two containers. I am running podman 4.3.1 on debian bookworm (kernel 6.0.8) What is wrong? I guess the first question I would have for you is why are you using VFS storage? And not overlay or fuse-overlay? Could there be other containers or storage that is un-accounted for? Did you do any podman builds? Or Buildah? ``` $ podman ps --all CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 2e7070eacb0f docker.io/library/alpine:latest touch /dan/walsh 6 days ago Exited (0) 6 days ago nervous_noether $ podman ps --all --external CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 2e7070eacb0f docker.io/library/alpine:latest touch /dan/walsh 6 days ago Exited (0) 6 days ago nervous_noether 9478fed6d8db docker.io/library/alpine:latest buildah 14 seconds ago Storage alpine-working-container ``` You could do a podman system reset and then remove all content from the storage with rm -rf ~/.local/share/containers To make sure there is nothing hidden there, Other then that I am not sure what could be showing the difference in storage.
