Split brain on cluster restart


#1

I'm curious: if I have a cluster of 3 nodes and have set the minimum number of master nodes to be 2 to prevent split brain issues, wouldn't it still be susceptible to split brain when restarting one of the nodes since it will only find two total?

I'm not super familiar with the idea of "split brain," so sorry if this is a stupid question.

No. That will be fine. If during this operation there is a disconnection between the 2 remaining nodes, then the cluster will be blocked waiting for a second node to appear again.
