I want to cluster MongoDB by using a replica set. I have created a three-node replicaset (rs0,rs1,rs2), and run the DBs in parallel with no issues. But when I shut down any two instance (one primary and secondary), the remaining secondary member is not made the primary, instead it remains as a secondary.
Step1:
- rs0: primary
- rs1: secondary
- rs2: secondary
Every thing is ok. When
Step2:
- rs0: stopped
- rs1: stopped
- rs2: secondary (This is not promoted to primary)
Why?
