This document assumes you are running at least 2 ProxmoxVE nodes. For the sake of the example, it will assume they are named `proxmox-node-01` and `proxmox-node-02`. We will also assume you are using TrueNAS Core. TrueNAS SCALE (should work) in the same way, but there may be minor operational / setup differences between the two different deployments of TrueNAS.

The first step is creating SSH trust between the ProxmoxVE cluster nodes and the TrueNAS storage appliance. You will leverage the ProxmoxVE `shell` to run the following commands.

## Configure Storage Provider
Now you need to set up the storage provider in TrueNAS via a series of "patches" provided by the community. You will run the commands below within a ProxmoxVE shell, then when finished, log out of the ProxmoxVE WebUI, clear the browser cache for ProxmoxVE, then log back in. This will have added a new storage provider called `FreeNAS-API` under the `ZFS over iSCSI` storage type.
