Fedora 19: How to resize/extend (LVM) partition?

1. Enlarge the disk using fdisk
   1. fdisk -l (to see the partition layout, typically we're dealing with /dev/sda2)
   2. fdisk /dev/sda
   3. d (delete a partition)
   4. 2 (if the part we want to grow is /dev/sda2; note this does not delete any data on disk)
   5. n (create a new partition)
   6. p (primary partition)
   7. 2
   8. <return> (default starting block, typically 14 since swap is first)
   9. <return> (default ending block, full size of the partition)
   10. make sure partition type is 8e for Linux LVM
       1. t
       2. 8e
   11. w (write changes to disk)
2. reboot to get new partition table
3. pvresize /dev/sda2
4. pvscan should show new larger size
5. lvextend -l +100%FREE /dev/vg_centos6/lv_root (-L +10G to add 10GB is another option)
6. resize2fs /dev/vg_centos6/lv_root
7. df should show new free space
