Well, 17a3585 ("pvscan: use alternate device names from DEVLINKS to check filter") fixes a different issue. I had a remark about it in my first post in this thread, but nobody has replied to that yet (hint: I'd appreciate if someone did). The "multipath_wwids_file" test makes most sense with an existing WWIDs file and "multipath=off" boot parameter, or multipathd disabled in some other way. Regards Martin
