Linux LVM Partition type not allowing more than 1.8Tb

I'm trying to partition a 4TB /dev/md0 (RAID 1) with cfdisk. When I create the Linux LVM (8e) partition, it happily says 4TB. When I reload cfdisk to check the partition, it says:

Name    Part Type  FS Type     Size (MB)
md0p1   Primary    Linux       1801629.41  
        Pri/Log    Free Space  2199023.26
Why can't I get the Linux LVM partition to use the full 4TB?


I messed around with it and realized that cfdisk wasn't converting it to GPT. I repartitioned with gdisk and it sees the full 4TB now.

There is a 2 TB limit for an MBR partition table. Instead use cgdisk to create a GUID partition table:
