Well I have a machine that has been running for a few years now with: 50GB / 2200GB LVM Grub2 has no problem with that, and it has a GPT partition table. debian:~# parted GNU Parted 1.8.8 Using /dev/sda Welcome to GNU Parted! Type 'help' to view a list of commands. (parted) print Model: ServeRA MAIN (scsi) Disk /dev/sda: 2250GB Sector size (logical/physical): 512B/512B Partition Table: gpt Number Start End Size File system Name Flags 1 17.4kB 50.0GB 50.0GB ext3 Root boot 2 50.0GB 2250GB 2200GB LVM lvm (parted) quit debian:~# fdisk -l WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted. Disk /dev/sda: 2250.1 GB, 2250128752640 bytes 255 heads, 63 sectors/track, 273562 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/sda1 1 267350 2147483647+ ee EFI GPT So I would say there is no requirement for a /boot partition. There might be a requirement for /boot to not be on LVM. Not sure. -- Len Sorensen -- To UNSUBSCRIBE, email to debian-boot-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
