Closed matthiaskrgr closed 8 years ago
Going to close this - there were changes in the way we select blocks and extents to be sure we don't miss files - specifically the find-dupes algorithm got better at that and we also have block dedupe now which shouldn't miss files either.
Opening an report so this isn't forgotten (we talked on irc/#btrfs about this shortly): Running duperemove on the same dir twice might re-dedupe files, apparently. I think I also saw files being deduped on one run, that were not touched by a preceding run, some while ago, but I can't confirm that right now.
First run:
second run:
