Typing out the error message ... [snip] Reading all physical volumes this may take a while ... No volume groups found Unable to find Volume Group "VolGroup00" [snip] I used a rescue disc distro and used dd to extract info subtible for vgcfgrestore, after which I did some other finagaling with vgchange and I can mount the volume and view the data on it, so it's there, vgscan/pvscan and lvscan all show it ... but as mentioned boot it's just not picked up on boot so it can be mounted as '/'. I thought I fixed it with the vgcfgrestore (changing /dev/hda2 to /dev/sda2) but obviously not ... any guidance is appreciated. thank you, brian
