What's the equivalent of creating a snapshot and reverting to it later on in ZFS (which is automated and usually hassle-free) in LVM2?

I've looked at the progress of this LVM2 feature a while ago and I've seen somebody working on it but it wasn't ready at the time. I've heard that LVM2 apparently has this feature available now.

Use lvconvert --merge, like this:

lvconvert --merge /dev/vgname/snapshot-name

This is not quick, as this requires to revert all the cow-actions on disk. Removing a snapshot is near-instant.

Thanks - I've actually looked at this without waiting for the answer but thought it'd be good to have it available here for the others. – Marcin Kaminski Dec 20 '12 at 1:47
