Consider a cluster of 3 nodes in 3 availability zones. One node in each zone.
zen.minimum_master_nodes is set to 2
All nodes are master eligible.
What will happen, if a partial partition occures, that will make node 1 and 2 see node 3, but not each other.
node 1 can see node 3
node 2 can see node 3
node 1 cannot see node 2
How will the cluster be formed in that case ? Will it remain available ?
