My current Ubuntu setup has root mounted to a LVM2 logical volume 'lvroot'. lvroot is 10G. I've been taking snapshots of lvroot, and then making dd backups of the snapshots (which creates a backup of lvroot as it existed at time snapshot was made), so those backups are 10G.
If I enlarge lvroot to 15G (lvextend and resize2fs), can I restore (via dd) the 10G backup to the now-larger lvroot? Would I need to run resize2fs immediately after the restore?
