To it, LVM appears as an unknown filesystem. You'll have to ask symantec to add LVM support. Just curious.. why even use ghost with RH Linux servers? I suppose multicasting everything is nice.. but a two step process where you use a kickstart for the install, and then a multicast file copy program (like mcp, http://www.cl.cam.ac.uk/users/kj234/mcp/) for any data would at least let you use free tools to accomplish your goal, and not leave you hanging when you switch filesystems. ;)
