[tomp (Thomas Parrott)]

There’s some more info in the spec:

[LXD] ZFS block mode

Project LXD Status Implemented Author(s) @monstermunchkin Approver(s) @stgraber @tomp Release 5.11 Internal ID LX036 Abstract This adds support for ZFS block mode. Rationale LXD currently doesn’t support ZFS block mode. Supporting this will allow the use of btrfs, ext4, and xfs filesystems on top of ZFS. Specification Design The following new configuration keys will be added for ZFS storage pools: volume.zfs.block_mode volume.block.mount_options volume.block.file…

And https://linuxcontainers.org/lxd/docs/master/reference/storage_zfs/#storage-volume-configuration

At the moment its only enabled at the pool level for new instances, or on a per-custom volume basis.

We will be adding the ability to control it on a per instance basis soon so keep an eye out for that in future releases.

You can do that to a single instance, creating a zvol storage in a existing dataset like I described in a message above:

lxc storage create zvol zfs source=rpool/zvol volume.zfs.block_mode=yes size="20GB" volume.block.filesystem="xfs" volume.block.mount_options="usrquota"

lxc launch images:debian/11/amd64 debian11zvol -s zvol
