If so, how? DM will automatically stack the physical and logical sector sizes based on the devices that are assembled into the DM device. So if you create an LV on a 4K device the associated DM device will report the same physical and logical block size. You can verify as much by looking at: /sys/block/dm-X/queue/physical_block_size /sys/block/dm-X/queue/logical_block_size There are more details about IO limits stacking here: http://people.redhat.com/msnitzer/docs/io-limits.txt _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
