Using the commands as suggested makes them easier to parse. You should be able to figure out how full a PV is that is part of an LV, but I'm not sure you can determine what parts of a pv an lv uses - or how much space an lv uses of a pv. For example: prompt> lvs --noheadings -o devices vg/lv /dev/sda(0) /dev/sdb(0) prompt> pvs --noheadings -o pv_used,pv_size /dev/sda 17.15G 17.15G So, you can use vgs to get the vg names, lvs to get the lv names in those vgs and the devices they live on, and pvs to get basic usage. If you want to do more, you might consider looking at /etc/lvm/backup/<vg name> brassow _______________________________________________ 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/
