Hi, I've just been copying large quantities of data from one btrfs volume to another, and while watching the progress of the copy, I've noticed something odd. $ mv source-dir dest-dir $ watch du -ms source-dir dest-dir This gives me a count of the size of the source and target directories, every 2 seconds. As expected, the size of the source dir stays constant, and the size of the destination directory increases. Except when it doesn't. Occasionally, while copying, the size of the dest-dir *drops* by several (tens of) megabytes. I'm not too worried about this, as it all seems to be copying the data OK, but it just seems a bit odd, and was wondering of there was a sane explanation for this behaviour. I'm running a linux.org 2.6.32.2 kernel, and the destination filesystem has just been created using the most recent btrfs tools.
