Hallo again,
I just purged the whole storage using podman system reset.
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

2e7070eacb0f docker.io/library/alpine:latest touch /dan/walsh 6 days

$ podman ps --all --external

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.
Best regards,
