If I can ask, what is this restrictions with "Btrfs filesystem aligned" and "FSCTL_SRV_COPYCHUNK wire request byte offsets and lengths align to the Btrfs sector-size" ?

It's not a problem. Thank you very much for all the help and explanations. It's much clearer...

Is this supposed to be supported in Samba 4.7.1? Server side copies work fine using a Windows client. From mac OS 10.13.2, there's a full transfer of a file being copied. $ smbutil statshares -a ================================================================================================== SHARE ATTRIBUTE TYPE VALUE
