Hi there, This would also interest me. Although ZfsOnLinux has done significant steps to make it possible, it doesn't seem to work fine yet. I wanted to use it to delegate backups to users who own a particular Zpool (using sanoid), but ended by customizing sudo commands and using znapzend as a backup daemon. I also think that overlays is the right way to go. Kind regards, Le mer. 15 avr. 2020 à 15:54, Daniel Walsh <dwalsh@redhat.com> a écrit :
Hello,
I would like to know to which extent ZFS is supported as filesystem for

In particular, I'd like to know if it is possible to use ZFS clones as a
backend for the container filesystem layering and if zfs datasets are usable for rootless containers (using zfs delegation). Is ZFS integration done transparently, i.e. are zfs dataset clones created when a new layer is created in a transparent way without explicit zfs commands?
Thank you
Best regards, Ingvar Bogdahn

While we have support for this in container/storage, I have no idea how many people use it. Most people use simple Overlayfs which I believe will work on top of zfs.
I am also not sure if ZFS will work as a backend in rootless mode. We use fuse-overlay to make this possible, so if you are attempting to run rootless, this might also be a concern.
The Linux kernel currently only allows not root users inside of a user namespace to mount certain types of file systems.
procfs, tmpfs, bind, sysfs, and fuse (I believe this is the currently limit).
So if zfs cloning requires a mount it will probably not work. _______________________________________________ Podman mailing list -- podman@lists.podman.io To unsubscribe send an email to podman-leave@lists.podman.io
