Detects when Redpanda hits any of these on startup or early runtime\: 1. Fails to create its crash_reports directory (POSIX error 13). 2. Heartbeat or node\-status RPC failures indicating a broker is down. 3. Raft group failure. 4. Data center failure
Detects high\-availability failures in NATS JetStream clusters due to\:
Detects when a Redpanda node becomes isolated (heartbeats fail) and triggers a Raft re\-election, indicating quorum loss.
HashiCorp Vault nodes in a Raft cluster are unable to communicate with each other for an extended period. This disrupts the Raft consensus mechanism which is critical for Vault's high availability and data consistency. When nodes can't communicate, the cluster may lose quorum, preventing operations like unsealing, authentication, or secret retrieval.
