I'm using whatever storage was provided by default podman install
(debian sid/bookworm) podman is 4.3.1 How can I reconfigure it to
different type? I assumed this has to be done in storage.conf but
this file is not present anywhere at all.

Best regards,

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
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.

Hallo,

I notice some disk space discrepancy when running rootless podman containers.
I use dedicated fs for podman storage mountrd to ~/.local/share/containers.
df and du show consistent used disk space:

  island:named [master]> df -h ~/.local/share/containers
  /dev/mapper/sys-containers   117G          84G   32G           73% ~/.local/share/containers

  island:named [master]> sudo du -sh ~/.local/share/containers/storage/{vfs,volumes}
  74G    /home/ivans/.local/share/containers/storage/vfs
  11G    /home/ivans/.local/share/containers/storage/volumes
  island:named [master]> 

But space usage shown by podman system df is about 44% less than reported above:

  island:named [master]> podman system df
  TYPE           TOTAL       ACTIVE      SIZE        RECLAIMABLE
  Images         32          5           39.49GB     25.96GB (66%)
  Containers     7           7           1.85GB      0B (0%)
  Local Volumes  2           2           10.83GB     0B (0%)

Volume space is practically same, it's vfs space (where as I understand images
and containers are located) that differs.

I also run buildah as same user, but buildah ls shows nothing.

I have ran podman system prune, but it reclaimed 0 bytes.

So is this extra space usage expected? Or is it sthing wrong with my storage?

Thanks and regards,
