This logs snippet http://pastebin.com/1gGAyf65 shows that there is a flaw in the mnesia erase logic. It seems has been introduced by the recent changes to the (post-)demote action.
In the snippet you can see that node-2 was not able to join to the node-5 because of the schema merge issue. The OCF RA normally handles this by mnesia erase. But there is none mnesia erase events for the master running (node-5). So perhaps that's why this situation was never resolved - because of the "bad master's mnesia"
