Hmmm… I did not setup ignores? Where do you get that from or is it misunderstanding because of “Ignore permissions” is set on both nodes? Just for info: I’ve set up ignore permissions initially because it’s the first time I try to sync data which all belongs to the “root” owner from ext4 (device A) to zfs (device B). I’m not using restrictions, so Syncthing is running as root and the zfs root is also owned by root. Not expecting trouble here.
