I learned about VDO today. [0][1] I'd never heard of it before, but I'm using Gentoo Linux and both the dm-vdo kernel module and the 'vdo' software provided by [1] are distributed by Gentoo... so this isn't some weirdo Red Hat thing. It looks like you manage and used these just like any other thin-provisioned LVM volume [2], but -like I said- I've not used this before, and have only just skimmed the docs, so it's possible that I'm missing something important.
