I have created a script for users who work on KVM virtual machines to be able to perform lvm snapshots on the logical volumes where their VMs are installed. Snapshot restores are performed via lvconvert --merge /dev/vg1/lv_snapshot What I want to know is, is there any easy way to unmerge the snapshot from the original?

Yes, when you first create the original LV, create a snapshot of it. To perform the equivalent of an unmerge you merge this snapshot.

I figured that much. So there is no offical undo feature then? – user160910 Apr 16 '13 at 13:16
