My DIY Ubuntu 18.04LTS NAS is running Samba 4.7.6.

I'm facing the following issue: I can't copy some files that have NTFS alternate data streams from Windows (10, latest version 1809 release build) to a Samba share, while this works fine for other files with ADS:

PS C:/tmp/withads> ls


 Directory: C:tmpwithads

Any clue?

If that would be related to xattr support / ext4 limitations, wouldn't that affect all files?

If this is really true, that's your issue:

copy nok.url //pnjnas/public
copy : There is not enough space on the disk : '\pnjnaspublicnok.url'
