Unable to get zfs working in container

[erict206]

Proxmox 6 is installed using the default lvm/ext4 filesystem. Then I set up zpools on other disks.

I created an Ubuntu 20.04 container, and want the container to be able to access the zpools. When I try to install zfsutils-linux into Ubuntu, I get these errors:
Failed to initialize the libzfs library. zfs-mount.service: Failed with result 'exit-code'. Failed to start Mount ZFS filesystems.

Any suggestions on why this is happening or how to fix?

AFAIU this will hardly work, no matter if it's a privileged or unprivileged (then for sure not) container.

You can pass a path on the pool through to the container as bind mount ( https://pve.proxmox.com/pve-docs/pve-admin-guide.html#_bind_mount_points ).

Passing through the disks to the container without mounting importing the pool on the host might (big maybe) work but even then I assume there will be some conflict between the kernel module that PVE ships and the one that the Ubuntu container wants to install. Keep in mind, a container is using the kernel of the host system.

@aaron, thank you for pointing this out to me. I starting setting up what I need as a KVM.
