Deployment Strategy Recommendation

Date: $(date)
Proxmox Host: ml110 (192.168.11.10)

Executive Summary

Based on the current status of both deployments, the recommended strategy is to:

✅ Keep LXC Containers (1000-2502) Active
❌ Shutdown VM 9000 (temporary VM)

---

Current Status Summary

LXC Containers (1000-2502)

• Status: ✅ 11 out of 12 containers have active services
• Resources: 104GB RAM, 40 CPU cores, ~1.2TB disk
• Readiness: Production-ready deployment
• Issue: VMID 1503 needs service file attention

VM 9000 (Temporary VM)

• Status: ⚠️ Running but network connectivity blocked
• Resources: 32GB RAM, 6 CPU cores, 1TB disk
• Readiness: Cannot verify (network issue prevents access)
• Issue: SSH/ping not accessible, QEMU guest agent not running

---

Recommendation: Keep LXC, Shutdown VM 9000

Primary Recommendation

Action: Shutdown VM 9000

Command:

qm stop 9000

Reasoning

✅ Advantages of Keeping LXC Containers

1. Production Ready

   • Properly configured LXC containers
   • 11 out of 12 services active and running
   • Individual resource allocation per node

2. Better Architecture

   • Resource isolation per node
   • Independent scaling capability
   • Better security boundaries
   • Individual node management

3. Service Status

   • Validators: 5/5 services started
   • Sentries: 3/4 services active (1 needs minor fix)
   • RPC Nodes: 3/3 services active

4. Resource Efficiency

   • Dedicated resources per node
   • No resource contention
   • Better performance isolation

❌ Reasons to Shutdown VM 9000

1. Network Connectivity Issues

   • SSH not accessible
   • Ping fails (destination unreachable)
   • QEMU guest agent not running
   • Cannot verify Docker containers status

2. Resource Savings

   • Free 32GB RAM
   • Free 6 CPU cores
   • Reduce total resource usage from 136GB to 104GB

3. Temporary Deployment

   • VM 9000 is intended as temporary/testing deployment
   • LXC containers are the production target
   • VM 9000 served its purpose (if it was used for testing)

4. Maintenance Overhead

   • Network issue requires console access to troubleshoot
   • Additional resource consumption for uncertain benefit
   • Cannot verify if services are actually running

---

Alternative: Fix VM 9000 Network

If VM 9000 is needed for specific testing purposes, you would need to:

1. Access VM Console

   # Via Proxmox web UI: https://192.168.11.10:8006 -> VM 9000 -> Console
   # Or try: qm terminal 9000
   

2. Verify Cloud-init Completion

   • Check: cat /var/log/cloud-init-output.log
   • Verify network configuration
   • Check SSH service status

3. Fix Network Configuration

   • Verify interface configuration
   • Restart network service
   • Verify routes and gateway

4. Verify Docker Containers

   # Once SSH accessible:
   ssh root@192.168.11.90
   docker ps
   cd /opt/besu && docker compose ps
   

However, this requires significant troubleshooting time and may not be necessary if LXC containers are already working.

Resource Comparison

Current State (Both Running)

Resource	LXC Containers	VM 9000	Total
Memory	104GB	32GB	136GB
CPU Cores	40	6	46
Disk	~1.2TB	1TB	~2.2TB

Recommended State (LXC Only)

Resource	LXC Containers	VM 9000	Total
Memory	104GB	0GB (stopped)	104GB
CPU Cores	40	0 (stopped)	40
Disk	~1.2TB	1TB (unused)	~1.2TB

Savings: 32GB RAM, 6 CPU cores freed up

---

Implementation Steps

Step 1: Verify LXC Services are Healthy

# Wait a few minutes for services to fully start
sleep 60

# Check all services
for vmid in 1000 1001 1002 1003 1004; do
    echo "Validator $vmid:"
    pct exec $vmid -- systemctl status besu-validator --no-pager | head -3
done

for vmid in 1500 1501 1502; do
    echo "Sentry $vmid:"
    pct exec $vmid -- systemctl status besu-sentry --no-pager | head -3
done

for vmid in 2500 2501 2502; do
    echo "RPC $vmid:"
    pct exec $vmid -- systemctl status besu-rpc --no-pager | head -3
done

Step 2: Fix VMID 1503 Service (if needed)

# Check service file
pct exec 1503 -- systemctl list-unit-files | grep besu

# If service file missing, may need to re-run installation
# (Check deployment scripts)

Step 3: Shutdown VM 9000

# Graceful shutdown
qm shutdown 9000

# Wait for shutdown
sleep 30

# Force stop if needed
qm stop 9000

# Verify stopped
qm status 9000

Step 4: Monitor LXC Deployment

# Check service logs for errors
for vmid in 1000 1001 1002 1003 1004 1500 1501 1502 2500 2501 2502; do
    if [[ $vmid -lt 1500 ]]; then
        service="besu-validator"
    elif [[ $vmid -lt 2500 ]]; then
        service="besu-sentry"
    else
        service="besu-rpc"
    fi
    echo "=== VMID $vmid ($service) ==="
    pct exec $vmid -- journalctl -u $service --since "5 minutes ago" --no-pager | tail -5
done

When to Keep Both Running

Consider keeping both deployments if:

1. Active Testing/Migration

   • Testing migration from VM to LXC
   • Comparing performance between deployments
   • Validating data migration process

2. VM 9000 Network Fixed

   • Network connectivity restored
   • Docker containers verified running
   • Active use case identified

3. Sufficient Resources

   • 136GB+ RAM available
   • 46+ CPU cores available
   • Clear benefit from both deployments

---

Decision Matrix

Scenario	Recommendation	Action
Production deployment needed	Keep LXC, shutdown VM	qm stop 9000
Testing/migration in progress	Keep both (temporarily)	Monitor both
VM 9000 network fixed & needed	Keep both	Verify Docker containers
Resource constrained	Keep LXC only	qm stop 9000
Uncertain use case	Keep LXC, shutdown VM	qm stop 9000

---

Summary

Recommended Action: qm stop 9000

Expected Outcome:

• ✅ Free 32GB RAM and 6 CPU cores
• ✅ Focus resources on production LXC deployment
• ✅ Reduce maintenance overhead
• ✅ Simplify deployment management
• ✅ VM 9000 can be restarted later if needed

Next Steps:

1. Verify LXC services are healthy
2. Execute qm stop 9000
3. Monitor LXC deployment
4. Document final deployment state
