Indeed, that was exactly one of the primary reasons the 'external_device_info_source="udev"' was added. Reimplementing other subsystem's logic is wrong because there's always some intrinsic logic there that may be omitted. Sooner or later, such approach will fail. I agree with you here. If not sharing information through udev due to various kinds of hatred about this part of the system, then alternatively, at least, calling a multipath library function from LVM to do the job. -- Peter
