I need some help with creating a new pool

so I have provisioned a linode instance and a new volume with 50Gb and I want to attach it to the instance
I want to lxd to use that volume attached to linode instance as storage pool (zfs or btrfs) for containers
how to do so?

I’m sorry but given the recent actions from Canonical regarding LXD:

We really can’t be providing support to LXD users on this forum anymore.

You may want to consider switching to Incus instead, or if you’d like to stay on LXD, you should reach out on the Canonical forum instead.

Sorry about that!
