LVM Thinly Provisioned Volumes

Today, I migrated my primary Ubuntu 17.04 development machine to put the root volume onto a thinly provisioned volume. There was a bit of a comedy of errors, so I want to outline what I should have done, vs what actually happened. What I should have done As in anything like this, it is important to start with known good backups. In my backup post, I describe how I’m doing that, and even testing it.

Backups

For my first post, I’d like to discuss some of my strategy that I use for backups. Backups are one of those things that most people realize are important, yet most people don’t really do them consistently. Aside from that, I’ve found that very few people test their backups. There are two scenarios that backups are important for: Disaster recovery. After a hard disk crash or other failure, how can I recovery a machine to the state it was in before the crash.
