(the root FS is not mounted). It uses an internal table for translating /dev/hda* and others to major/minor(see init/main.c). Try with grub (here /dev/vg00/lvol1 is the root fs): title=GNU/Linux Debian 2.2 (potato) kernel (hd0,1)/vmlinuz-2.2.19 root=3a00 ramdisk_size=8192 vga=10 # ^^^^ <major><minor> of the lv device in hex initrd (hd0,1)/initrd-lvm-2.2.19.gz _______________________________________________ linux-lvm mailing list linux-lvm@sistina.com http://lists.sistina.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://www.sistina.com/lvm/Pages/howto.html
