I have a server with 2 x 1TB drives. When I purchased the server they install centos 6 with software raid 1. With partition table for the mirrored drives looking like such: /boot 500MB swap 1GB / rest of free space Without having to reinstall and request a custom a partition table, I'd like to shrink the / partition so I can increase the swap space to ~30GB. I have vague knowledge in this area but I wanna be sure. Can anyone instruct me how to go about this? Thanks beforehand
