- Add upfront reservation of all calculated gRPC ports before allocating HTTP ports to prevent collisions where an HTTP port allocation could use a port that will later be needed for a gRPC port calculation. Example scenario that is now prevented: - Master HTTP reallocated from 9333 to 9334 (original in use) - Filer HTTP search finds 19334 available and assigns it - Master gRPC calculated as 9334 + GrpcPortOffset = 19334 → collision! Now: reserved gRPC ports are tracked upfront and HTTP port search skips them. - Improve admin server gRPC port fallback error handling: - Change from silent V(1) verbose log to Warningf to make the error visible - Update comment to clarify this indicates a problem in the port initialization sequence - Add explanation that the fallback calculation may cause bind failure - Update ensureAllPortsAvailableOnIP comment to clarify it avoids reserved ports
