I am running my DVR server on a DS218+ with 2 separate volumes and storage pools. Each physical hard drive is its own storage pool and volume. I separated the drives by 1.) DVR recordings and 2.) all other media (Plex, movies, music, photos etc.).
At some point I anticipate possibly getting close to capacity for the DVR volume (6TB Ironwolf drive), as it is just over 70% right now. I understand the concept of adding a storage path, but when I try to do so via the web UI, I can only add folders that are on volume 1. There is no option to select anything from volume 2.
Oddly, I can import movies from my Plex server running on volume 2 and Channels can see them just fine. I just selected the option to back up one directory level from "volume 1" and then could see "volume 2". That option just isn't there for the additional DVR storage path though.
See the pics from the web UI to illustrate what I'm referring to. Thanks for any feedback!!
