fdisk problems with large partitions

I recently upgraded my 3ware 9550SX-8LP RAID5 array from 250 GB drives to 1 TB drives. After the lengthy RAID initialization process, I tried to create a partition using fdisk. Unfortunately, fdisk seemed to only create a partition size of about 400 GB instead of the 6+ TB that I expected. For reference:

  • fdisk version: v2.12q
  • OS: SuSE Linux 9.3 (x86-64)
  • kernel:

After searching around for awhile, I came across Linux Creating a Partition Size Larger than 2TB by Vivek Gite. The article recommended using parted; my system had GNU Parted 1.6.21 and it worked just fine. Do remember that you need to mklabel gpt. And now df -h lists the partition at a hearty “6.4 T”.

For some reason I have the urge to do a little jig and sing “Mo’ money, mo’ money, mo’!”
