# RPC Node Testing - Complete Summary **Last Updated:** 2026-01-31 **Document Version:** 1.0 **Status:** Active Documentation --- **Date**: 2026-01-17 **Status**: Testing Complete - Partial Success --- ## Executive Summary ### Current Status - **Containers Running**: 11/12 (2301 has startup error) - **RPC Responding**: 4/12 nodes (33%) - **Block Synchronization**: ⚠️ Nodes at different block heights (syncing in progress) - **Peer Connections**: 4 nodes with peers (6 total connections) - **Chain ID**: ✅ All nodes on Chain 138 (0x8a) --- ## Detailed Test Results ### Test 1: Container Status | VMID | Status | Name | Service Status | |------|--------|------|----------------| | 2101 | ✅ Running | besu-rpc-core-1 | Active | | 2201 | ✅ Running | besu-rpc-public-1 | Active | | 2301 | ❌ Stopped | besu-rpc-private-1 | Startup error | | 2303 | ✅ Running | besu-rpc-ali-0x8a | Active (starting) | | 2304 | ✅ Running | besu-rpc-ali-0x1 | Active (starting) | | 2305 | ✅ Running | besu-rpc-luis-0x8a | Activating | | 2306 | ✅ Running | besu-rpc-luis-0x1 | Active (starting) | | 2307 | ✅ Running | besu-rpc-putu-0x8a | Active (starting) | | 2308 | ✅ Running | besu-rpc-putu-0x1 | Activating | | 2401 | ✅ Running | besu-rpc-thirdweb-0x8a-1 | Active | | 2402 | ✅ Running | besu-rpc-thirdweb-0x8a-2 | Active | | 2403 | ✅ Running | besu-rpc-thirdweb-0x8a-3 | Active (starting) | **Result**: 11/12 containers running --- ### Test 2: RPC Connectivity #### Fully Operational Nodes (4/12) - ✅ **2101 (192.168.11.211)**: Block 1135876, Port 8545 listening - ✅ **2201 (192.168.11.221)**: Block 1135876, Port 8545 listening - ✅ **2401 (192.168.11.241)**: Block 1149992, Port 8545 listening - ✅ **2402 (192.168.11.242)**: Block 1149992, Port 8545 listening #### Starting/Nearly Ready (7/12) - ⏳ **2303 (192.168.11.233)**: Process running, port not ready - ⏳ **2304 (192.168.11.234)**: Process running, port not ready - ⏳ **2305 (192.168.11.235)**: Process running, port not ready - ⏳ **2306 (192.168.11.236)**: Process running, port not ready - ⏳ **2307 (192.168.11.237)**: Process running, port not ready - ⏳ **2308 (192.168.11.238)**: Process running, port not ready - ⏳ **2403 (192.168.11.243)**: Process running, port not ready #### Not Available (1/12) - ❌ **2301 (192.168.11.232)**: Container cannot start (pre-start hook error) **Result**: 4/12 nodes fully responding (33%) --- ### Test 3: Block Synchronization **Current Block Heights**: - 2101: Block 1,135,876 - 2201: Block 1,135,876 - 2401: Block 1,149,992 - 2402: Block 1,149,992 **Synchronization Status**: ⚠️ **In Progress** - Block difference: 14,116 blocks - Nodes are actively syncing to catch up - 2101/2201 and 2401/2402 are synchronized within their groups - All nodes progressing toward latest block **Note**: This is expected behavior when nodes are starting/syncing. As nodes catch up, block differences will decrease. --- ### Test 4: Peer Connections | Node | IP | Peer Count | |------|----|-----------| | 2101 | 192.168.11.211 | 1 peer ✅ | | 2201 | 192.168.11.221 | 1 peer ✅ | | 2401 | 192.168.11.241 | 2 peers ✅ | | 2402 | 192.168.11.242 | 2 peers ✅ | **Result**: 4 nodes with peers, 6 total peer connections **Analysis**: Nodes are forming peer connections. As more nodes come online, peer count should increase. --- ### Test 5: Service Health #### Port 8545 Listening Status - ✅ Listening: 2101, 2201, 2401, 2402 (4 nodes) - ⏳ Not yet listening: 2303, 2304, 2305, 2306, 2307, 2308, 2403 (7 nodes) #### Besu Process Status - ✅ All running nodes have Besu processes active **Analysis**: Services are starting. Nodes with processes but no port listening are still initializing (normal during startup). --- ## Issues Identified ### 1. Container 2301 Startup Failure ⚠️ **Status**: Cannot start **Error**: `lxc_init: 845 Failed to run lxc.hook.pre-start` **Impact**: 1/12 containers unavailable **Action**: Requires investigation of pre-start hook configuration ### 2. Nodes Still Starting ⏳ **Status**: 7 nodes have processes but RPC not ready **Impact**: Normal startup behavior - services need more time **Expected Resolution**: Nodes should become available as Besu finishes initializing ### 3. Block Synchronization Gap 📊 **Status**: 14,116 block difference between node groups **Impact**: Expected during sync - nodes catching up **Expected Resolution**: Nodes will sync to latest block over time --- ## Configuration Status ### Files Deployed ✅ - `static-nodes.json`: 15 enodes (all unique) - `permissions-nodes.toml`: 15 enodes (matches static-nodes.json) - Files deployed to all 11 running containers ### Configuration Verified ✅ - All enode IDs are unique - static-nodes.json matches permissions-nodes.toml - Chain ID: 0x8a (138) confirmed --- ## Progress Timeline ### Initial Testing (Start) - 2/12 nodes responding - 0 block sync verification (only 2 nodes) - Permissioning errors detected ### After Configuration Fix - 4/12 nodes responding (100% improvement) - Block sync data available - Permissioning errors resolved - Peer connections forming ### Current State - 4/12 nodes fully operational - 7/12 nodes starting (expected to become available) - 1/12 node has startup error --- ## Next Steps & Recommendations ### Immediate Actions 1. ✅ **Configuration files deployed** - Completed 2. ⏳ **Wait for services to start** - In progress (7 nodes still starting) 3. ⚠️ **Investigate container 2301** - Pending ### Short-term (Next 15-30 minutes) 1. **Monitor node startup** - Check every 5-10 minutes for RPC availability - Verify port 8545 starts listening on all nodes - Confirm all nodes become responsive 2. **Verify block synchronization** - Monitor block heights as nodes sync - Confirm all nodes reach same block height - Check sync status via `eth_syncing` 3. **Check peer connections** - Verify peer counts increase as more nodes come online - Confirm nodes can discover and connect to each other ### Medium-term (Next few hours) 1. **Fix container 2301** - Investigate pre-start hook error - Resolve or recreate container - Verify container can start successfully 2. **Full network verification** - All 12 nodes responding to RPC - All nodes synchronized to same block - Peer connections established across network - All RPC methods functioning correctly --- ## Test Commands ### Quick Status Check ```bash # Check RPC connectivity for ip in 192.168.11.211 192.168.11.221 192.168.11.233 192.168.11.234 192.168.11.235 192.168.11.236 192.168.11.237 192.168.11.238 192.168.11.241 192.168.11.242 192.168.11.243; do timeout 3 curl -s -X POST -H "Content-Type: application/json" \ --data '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}' \ http://$ip:8545 | grep -q "result" && echo "✓ $ip" || echo "✗ $ip" done ``` ### Comprehensive Test ```bash bash scripts/test-rpc-nodes-complete.sh 192.168.11.10 ``` ### Block Sync Check ```bash # Get block numbers for all nodes for ip in 192.168.11.211 192.168.11.221 192.168.11.241 192.168.11.242; do block=$(curl -s -X POST -H "Content-Type: application/json" \ --data '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}' \ http://$ip:8545 | grep -o '"result":"[^"]*"' | cut -d'"' -f4) printf "%d\n" $block done | sort -n | awk '{if(NR==1)min=$1; max=$1} END {print "Min:", min, "Max:", max, "Diff:", max-min}' ``` --- ## Conclusion **Current Status**: ✅ **Progressing Well** - 4/12 nodes fully operational (33%) - 7/12 nodes starting (58%) - expected to become available - 1/12 node has error (8%) - requires investigation **Key Achievements**: - ✅ Configuration files deployed correctly - ✅ Permissioning errors resolved - ✅ Peer connections forming - ✅ Nodes actively syncing - ✅ No duplicate enode IDs **Expected Outcome**: - Within 15-30 minutes: 8-11 nodes should be fully operational - Within 1-2 hours: All nodes should be synchronized - After fixing 2301: 11/12 or 12/12 nodes operational **Overall Assessment**: **Good Progress** - System is working as expected during startup/sync phase. --- **Last Updated**: 2026-01-17 **Next Review**: Wait 15-30 minutes and re-test
