Summary

• When there are no nodes in the peers.json file, the nodes fail to form a quorum.
• If we wish to remove the failed node’s IP from the alive nodes, we need to restart all the alive nodes after editing the peers.json file.
• With “leave_on_terminate”=false and “skip_leave_on_interrupt”=true configurations set, the peers are not removed from the peers.json.
