I wouldn't do that. Instead, I would create a new logical partition, "format" it as lvm physical volume and then extend the volume group to use this partition as well. I think this can be safely done like this: * turn off lvm; * note down the exact starting and ending *sector* of partition 5 (using fdisk -lu) * use fdisk and delete partition 5 and 2, then re-create partition 2 up to the full disk size * re-create partition 5 making sure it's on exactly the same starting and ending sector as it was before * create new partition 6 > You are getting to a size where msdos partition tables are risky. > Don't they crap out at 2TB? They do. But the "2TB" disk is actually 2000GB, which is safe (it takes more than 2048GB to run into trouble with m$dos partitions).
