Yeah, it's probably that. I don't think these units are expressed in anything else but extent size units (http://tldp.org/HOWTO/LVM-HOWTO/pe.html). I did the following test: I created two LV and compared the LVM metadata against the output of lvdisplay -m, here's what I got: First volume, LVM metadata: segment1 { start_extent = 0 extent_count = 256 type = "striped" stripe_count = 1 stripes = ["pv0", 2568] } First volume, lvdisplay -m: --- Segments --- Logical extent 0 to 255: Type linear Physical volume /dev/sda3 Physical extents 2568 to 2823 Second volume, LVM metadata: segment1 { start_extent = 0 extent_count = 2567 type = "striped" stripe_count = 1 stripes = ["pv0", 1] } Second volume, lvdisplay -m: --- Segments --- Logical extent 0 to 2566: Type linear Physical volume /dev/sda3 Physical extents 1 to 2567 Or have I got it completely wrong? _______________________________________________ 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/
