I have created a yaml file in /var/lib/rancher/k3os/config.d/ called harvester-mount.yaml with the following content:

```auto
runCmd:
  - "sudo mount UUID=18dae58b......c7cdc94a4b /var/lib/longhorn-sdb"

```

(make sure you created the mount path)

The UUID can be found with:  
sudo lsblk -f /dev/sdb

After a reboot, Harvester will mount the 2nd disk. You then have to add it in Longhorn. That can be done by enabling Rancher in the settings of Harvester. Then go into Rancher, select the Local cluster and go into Longhorn. Add the disk by edit the node and add the path where you mounted the disk, ie. /var/lib/longhorn-sdb/

Hope this helps.
