Need some help developing a strategy

Hi all-

I've got a pair of Debian servers running some django sites, and they've been working good for me for quite a while.

The problem is that when I set them up, I did not really configure the system the way I should have, and our PLM system is storing files in the Root filesystem. So now I have a Raid 5 array sitting basically unused, and a root partition that won't behave because it is maxed out.

I have resized partitions with Gparted before, but only on single disks- I used a live usb to look at it, but it doesn't rebuild the array and I don't want to mess the entire system up. They are LVM partitions, so I am hoping that there is a way to simply grow the root folder into the home partition without too much hassle. The home partition exists, but I don't really use it for anything. If I shrink it and lose some data, I don't really care about that- I just want the root partition larger.

Here's what lsblk gives me:

Anyone able to spare a few moments to help me out? Some of the packages needed for the software are older, and I'd rather not reinstall if it can be avoided.

Thanks!
