So, what I am not real clear on are what subvolumes exist on my NAS. I was assuming that /data is a subvolume and that all shares are subvolmes (in order to do snapshots independently). That basically right?
When I turned on for one of my shares (btrfs quota enable /data/Media) I was expecting the command to show the usage to basically show me the snapshots for the subvolume /data/media. Instead it looks like it showed me all of them.
Am I misunderstanding the subvolume structure on the NAS? Anyone else want to try to figure this out? It actually looks really useful. Might have to write some PHP this weekend to generate reports.
