Thank you for your reply. I am not planning on running DRBD at all. I just want to borrow ideas from DRBD code and implement them in Linux LVM Mirror. Many things are common but few are different between DRBD and Linux LVM Mirror. I am trying to understand, if generation number itself would be sufficient for Linux LVM Mirror. Yes, I did read the publications listed there. Thanks, Malahal.
