Your corosync.conf looks correct.

From sheep[1-3].log, your Sheepdog directories contains wrong
information about node membership histories.  I'm not sure why it
happened, but it would work for you to clean the store directories and
run 'collie cluster format' again.

I highly recommend to upgrade Sheepdog to version 0.2.3 or use the
latest development code:

It includes many important bug fixes.
