Distributed Failover Manager
Automatic Node Failure Detection and Recovery
System detecting distributed node failures and redistributing tasks to surviving nodes
Purpose
System detecting distributed node failures and redistributing tasks to surviving nodes
Context
Child of L2-CDH-DIST
Principles
- ▸Heartbeat monitoring detects node failures within configurable timeout period
- ▸Task migration moves critical functions from failed node to backup node
- ▸Graceful degradation reduces functionality proportional to lost nodes
- ▸Recovery procedures attempt restart of failed node before declaring permanent failure
Typical implementations
- ▸ISS MDM redundancy management
- ▸Distributed computing fault tolerance (Raft, Paxos consensus)
- ▸Kubernetes pod failover (adapted concept for embedded systems)
Lunar considerations
- ▸Node failures expected over 100-year mission - must be handled gracefully
- ▸Backup capacity must be sufficient to absorb multiple simultaneous node losses
- ▸Failed nodes added to robotic maintenance queue for replacement
