[PATCH pve-container 0/1] Proposal for adding zfs dataset mounting possibility

[Konstantin Filippov]

No, this dataset not added as “dir” - it’s mounted as ZFS filesystem inside container so it’s not a file. And about proxmox provided zfs backend - I understand that it’s better to just use existing option, but there is use cases where existing mechanism isn’t usable - for example when you need to mount dataset inside container only, to make files on it visible only inside container.

Best regards,
Konstantin

I've prepared a little patch for pve-container package which adds a fourth "category" named "zfs" - so with this patch it's possible to add such ZFS dataset into container config in a form "mpN: <ZFS pool name>/<dataset path>,<mount path>". This new type can be useful in some cases - for instance when we need to mount ZFS dataset in the container but need to keep this dataset not mounted on the host.
