Btrfs subvolume questions

Yes you have to mount it, and if you want to convert a directory into a subvolume what you can do is create a snapshot using

btrfs subvolume snapshot <name of subvolume containing folder> @new_subvol

Then you could go into the subvolume and delete everything other than @new_subvol/home for instance and move everything in home to the root of the new subvolume with something like

mv @new_subvol/home/* @new_subvol

Then you could delete the original directory and move the newly created snapshot into its place.


  1. Yes.
  2. No.

At least not at the moment.
