The extent size should be chosen to be a convenient size for the system administrator. Typically 4-16M these days; it tends to get bigger as hard disks grow. So the extent size is going to be far too large for you to worry about files being broken across extent boundaries. Think about the percentage of ios that will incur this extra seek that you are concerned about. - Joe _______________________________________________ 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/
