I know the advantages. I actually converted my servers to use LVM volumes
for the VMs and database. Snapshots are the way to go for backing up live
systems. I have been doing some research into how to accomplish
differential block level backups from snapshot to snapshot.

I guess my question was more amorphous. I have a couple potential storage
applications that could be implemented with LVM as a component. I'm also
looking into ZFS and Btrfs. I'm not looking for a compare/contrast.

I'm looking to hear from people using it, things they like, things they
dislike, oddities they've encountered, etc.
