Well, *that* we have, as long as the parent devices are real (non-devicemapper) devices. So if /dev/sdc and /dev/sdg are both paths to the same filesystem, and dm-multipath has created /dev/mapper/filesystem as the multipath device to that filesystem, any devices with /dev/mapper have priority over non-dm devices, so /dev/mapper/filesystem will get returned first. - Ted -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
