Based on the information provided:
- Nodes 1 and 2 detected that the other node was missing heartbeats and initiated eviction processes simultaneously.
- However, node 2's CSSD correctly detected that node 1 was still actively updating the voting disks based on the disk heartbeat information, indicating it was still active.
- To prevent a potential split-brain situation, node 2's CSSD aborted the local node instead of continuing with the eviction process, since node 1 appeared to be the larger and active cohort.
- This demonstrates how Oracle Clusterware is designed to detect and resolve potential split-brain situations during node failure/ejection events to maintain cluster integrity. The CSSD on node 2 made the right decision to
