And if you put a big file in CephFS and then deleted it, the data will be deleted from the RADOS cluster asynchronously in the background (by the MDS), so it can take a while to actually get removed. :) If this wasn't the behavior then a file delete would require you to wait for each of those (10GB/4MB=)2560 objects to get deleted in separate network calls before returning!
