[Podman] Re: Follow-up: Rootless storage usage

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,

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 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. > Best regards, > -- > On 23.12.2022 19:43, Михаил Иванов wrote: >> 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?
