Hi. I've just find out that in last unraid 6.10.0-rc2 version this function works as I would like. So if you copy file(s) between share(s) on one physical disk using samba it will not require any additional space by default and it's going very fast. EXCELLENT. :)))))) Thanks for the developers they realized this functionalities of btrfs.
Is it possible to add the option(s) mentioned above?
Actually I tried to add "vfs objects = btrfs" into /etc/samba/smb-shares.conf than restart samba but this functionality still not working...
On ubuntu it works perfect without any issue for example. Why it doesn't work on unRAID?
