As a followup on the discussion we had on how to do a live data switch on a partition without unmounting it since it's busy, it came back to how do you know what changed between 2 snapshots.
btrfs send giving a file list of what was added/modified/removed is the long term answer, and Filipe is working on patches that will offer this in the future (thanks Filipe). In the meantime, I found a hack/script that gives a partial diff between 2 snapshots, called it btrfs-diff but then remembered that there isn't a page for it. So, I made one, along with example usage: http://marc.merlins.org/perso/btrfs/post_2014-05-19_Btrfs-diff-Between-Snapshots.html Hope this helps. As another temp hack, I tried to look at a quick way to parse btrfs send output to just spit out filenames, but that wasn't too trivial (as in with sed/perl). If someone has something better, please share :) Thanks, Marc -- "A mouse is a device used to point at the xterm you want to type in" - A.S.R.
