Create 8 1gig files. (check free space on disk) Create a snapshot. Delete all 8 1gig files. At this point you would expect the free space on disk to match what it was when you just checked it earlier (see above). However, for a small amount of time (a minute or so ?) You actually get a fair amount of that space back - and it is reported as free in `df`. And then it goes back down to what it was when you made the snapshot. Why does df report (temporarily) a gain in disk space after deleting these files (which should not result in any disk space gain) Thank you.
