I'm now looking at this, but you've done an error. You say that You must create the snapshot-origin device before you can create snapshots. This is totally wrong. The whole point of my document is to show that you can create snapshots *WITHOUT* having a snapshot-origin device (yes, I did it). And while the LVM setup (with snapshot-origin) is often used and well known, the possibility to do without the snapshot-origin, and more important to write on the snapshots, is something which is not widely known at all. In fact, UML community has been using an in-house version of the same feature, which cannot be mounted on the host due to missing code. > See also http://people.redhat.com/agk/talks/FOSDEM_2005/ > (slides 15-27) Not yet had time to look at those, sorry. > You might like to convert some of those diagrams to ASCII > and include them? If you feel like doing this, ok, but I'm not normally a documentor. > Alasdair -- Inform me of my mistakes, so I can keep imitating Homer Simpson's "Doh!".
