Try adding

  lustre.* skip

to /etc/xattr.conf (cf.
<https://doc.lustre.org/lustre_manual.xhtml#lustre_configure_multiple_fs>).
Haven't tested yet, but Samba's EA handling seems to be libattr-based,
so the above tweak should be sufficient to keep smbd off of these
fs-specific attributes.

Kind regards,

Daniel
