In our organization, we've set up 3 nodes, two of them are storing the data, and the last one is a kind of 'Tiebreaker'.
When one of the node fails, Master is easily switched to the other machine, and everything seems to be working properly - and that it's okay!
The problem begins when two nodes fail, so let's say that for example it would be, tiebreaker(node-3) and node(node-2) which currently was not selected as a master. After that, only one node(node-1) left, which was previously chosen as the master one - Unfortunately, but this node that was left, also does not work anymore after failure of node-3 and-2. Why it is like that? If previously it was a master, why does node-1 stop working?
