Redpanda Quorum LossHigh
Mitigation: 9/10

CRE-2025-0092View on GitHub

Description

Detects when a Redpanda node becomes isolated (heartbeats fail) and triggers a Raft re-election, indicating quorum loss.\n

Mitigation

**Immediate Actions:**\n 1. Reconnect or restart the isolated node:\n ```bash\n docker start redpanda2\n ```\n 2. Check Redpanda logs to confirm it rejoins the Raft cluster:\n ```bash\n docker logs redpanda2 --tail 20\n ```\n 3. Verify leadership status with:\n ```bash\n rpk cluster show\n ```\n**Long-term Fixes:**\n - Ensure minimum 3 voting replicas for quorum.\n - Monitor inter-broker network latency and packet loss.\n - Deploy Redpanda behind a stable DNS or static IPs.\n
