"mpath_uuid is used for dm multipath devices, reported by sysfs." So users are supposed to use "mpath_uuid" if they want to use multipath devices as PVs? What if the user simply uses "sys_wwid" or "sys_serial" for a multipath device? Will LVM perform any kind of multipath detection, and if yes, how? Martin
