I am using LVM to debug a custom ASIC virtualization chip for my company. I have found it quite useful. One queston though, I have written scripts to convert lvdisplay -vv table output into our own mapping structures, but found this to be of limited use for snapshots. Is there a way to find out where the changed snapshot data actually resides physically? if you do lvdisplay for a snapshot volume, it only gives you the LE->PE maps for the *original* LV. it does not show you what extents the *changed* data got moved to, so i don't know how to track it down and verify it. is there another way to do this or is it a possible enhancement to lvdisplay for snapshot volumes? Thanks, Dave _______________________________________________ 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/
