If I'm doing a multipath -r later, a new mpath0 appears and cannot be removed (mpath0: map in use) due to uninteruptible process (kpartx and blkid). Doing echo 1 > /sys/block/sd*/device/delete as a last step (and before issuing multipath -r) seems to fix the issue, so the problem here maybe lies in udev which is not removing the nonexistent devices after a SCSI rescan?
