Most likely is that the commands necessary to activate the LVM at boot time are not being run. Test this theory by running as root: vgchange -a y and mount the device. If it then works, check the usual things, like /etc/init.d/lvm is in your boot runlevel Also check dmesg for obvious errors. -- alan dot mckinnon at gmail dot com
