From: Bobi Jam <bobijam.xu@xxxxxxxxx> Tools like rsync, tar, cp may copy and restore the xattrs on a file. The client previously ignored the setting of trusted.lov/lustre.lov if the layout had already been specified, to avoid causing these tools to fail for no reason. For PFL files we still need to silently eat -EEXIST on setting these attributes to avoid problems.
