ERROR: not a btrfs filesystem

I just finished converting all my drives to btrfs, for no other reason that I want to use the snapshot feature. Mainly I want to perform hot incremental backups of my (cache-stored) VM's and send the snapshots to a backup directory on the array.


So I was a bit disappointed when I see I can't use btrfs features on the user shares. Creating a subvolume on a user-share just gives the error "ERROR: not a btrfs filesystem". I guess the driver providing the unified name space doesn't pass through these things.


Are there any workarounds for this, except using a dedicated disk for the backups and access it directly?

Each array disk in Unraid is a separate filesystem, this has many advantages but also some disadvantages, you'll need to use a disk share instead of user share for that.
