You can claim that it's not a standard use case, but first Michael hit that, now me. There's at least one more case - https://lists.samba.org/archive/rsync/2011-December/027117.html The count of such cases will be increasing and the sooner it will be fixed - the less pain it will bring to the users. I know fixing that is a big structural change, but it will become worse with time. If it's not going to be fixed - I don't care. Right now I'm forced to migrate to old mdadm raid-1 or ZFS. The sad thing is that I really LOVED btrfs. Only that. ^__^ K.
