I have a node program that writes extended attributes to files (fs-xattr). This works from a remote machine connected over SMB but if I try to run the command on the machine itself it says extended attributes are not enabled.

How is SMB able to do this? Maybe it has a fallback?

Specifics

  • The machine that I need extended attributes on is a Synology RS2414rp+ DSM 6.2.
  • From macos if I connect over SMB I can write and read extended file attributes.
  • If I ssh into the Synology box I cannot write extended attributes to files
  • fstab on the Synology does not have user_xattr on the volume

Secondary Question

I cannot find a clear answer on how to enable user_xattr on a Synology box. I'd like to understand the first question but I believe enabling user_xattr will also solve my problem.

Thank you for your help.

    Curious if you ever found out more about this? I have the same questions about support for extended attributes on Synology boxes. A [related question](https://community.synology.com/enu/forum/1/post/125222) was posed on a Synology forum about 2 years ago. – mhucka Apr 13 '21 at 02:39

    @mhucka - No, unfortunately, I never found a good answer. – styks Apr 13 '21 at 12:27
