LVM: Using 2TB Volumes for Volume Groups

Mon, 28 May 2012 00:00:00 +0000

Occasionally you will have the need to use physical volumes which exceed the limits of the standard DOS partitioning scheme. When you run into this a quick fdisk -l will reveal that you will need a new way to partition your disks.

Fdisk will produce output similar to this…

WARNING: GPT (GUID Partition Table) detected on '/dev/sdb'! The util fdisk doesn't support GPT. Use GNU Parted.

WARNING: The size of this disk is 2.3 TB (2290828181504 bytes).
DOS partition table format can not be used on drives for volumes
larger than 2.2 TB (2199023255040 bytes). Use parted(1) and GUID
partition table format (GPT).

Use Parted to Create a Partition Using the Whole Disk

Parted is able to handle large volumes which are not able to be modified with fdisk. Here we are going to launch parted, and then create the partition with a size of 1 -1 which means that it will use it all until it gets to the end. You can additionally specify the number in megabytes, so 1 1024 would start at 1 and go until 1024 giving you a 1GB partition.
