Subject: [LSF TOPIC] [ATTEND] Next3 snapshots in Ext4

Hi,

I got comments from many people, including Ric, that would like to see
Next3 snapshots merged into Ext4,
so I would like to attend and discuss some of the issues related to the merge.

Agenda from the top of my head:
1. Overview of the Next3 snapshots implementation in Ext3
2. How to deal with move-on-write of data blocks in extent mapped files?
3. How to guaranty snapshots data consistency on copy-on-write of
non-journaled data blocks?
4. What are the implications of delayed allocation on consistency of snapshots?
5. how to deal with file fragmentation due to move-on-write?

Thanks,
Amir.
