A small group of us (Johnny, Nikanth, Suresh and me) met and discussed a paper titled “Design and Implement of Snapshots in Linux Block Level”. Nikanth led today’s _very_ active ~2 hour session. Basic snapshotting techniques were discussed, some possible variations on the ideas presented in the paper were also debated. We looked at dm snapshot, and some related code too. Nikanth and Suresh with their block layer and filesystem knowledge were very helpful in steering discussion.
On the whole it was very enjoyable 2 hours
