I am trying to implement a better 'master selection' scheme in Linux
dm-mirror/LVM2 code.

I read that DRBD used to have generation number scheme instead of the
current UUID scheme. I read that the old 'generation number' scheme
doesn't work for more than 2 nodes. Can some please explain how/why?
Would a time stamped generation number help for more than 2 nodes?

I understand that a generation number scheme would NOT work for quick
resynchronization for more than 2 nodes, but would that help if we were
to do full-resynchronization?

Thank you for your time.
