Add disks to extend LVM SWAP and / home area

Thing you want to do

Create a physical volume on the newly added disk (20GB) and expand the logical volume size of swap and / home by + 10GB.

environment

-Virtualization software: vmware workstation ・ OS: CentOS 6.5

important point

This time, the logical volume size of / swap and / home is expanded, so you can work while the OS is online, but if you want to reduce the logical volume size of / (root), use LIVECD and set it in rescue mode. is needed.
