Hi all, I am looking for a way to recover my primary VolGroup00 that has my root partition. Here is my scenario; 1 - I add an external drive to my VolGroup00 which is sdc1. 2 - I make that external drive a snapshot of my / 3 - After I remove that new volume of sdc1 using lvremove, all os fine. 4 - When I turn off the sdc1 drive, I loose my VolGroup00. If by chance, the sdc1 breaks in such a way that the system doesn't se it any more and the system happens to reboot, it will longer recognize a VolGroup00 and therefore not boot. I backed up my original /etc/lvm to /etc/lvm.backup and would like to know how I can restore it from booting to a LiveCD and simply restoring the files located in /etc/lvm.back/backup/VolGroup00 which is my original metadata config. - Brian
