# RPC Troubleshooting - Complete Summary

**Date**: $(date)  
**Issue**: RPC-01 (VMID 2500) troubleshooting and resolution

---

## 🔍 Issue Identified

RPC-01 (VMID 2500) was experiencing multiple issues preventing proper operation:

1. **Missing Configuration File**: Service expected `/etc/besu/config-rpc.toml` but only `config-rpc-public.toml` existed
2. **Service File Mismatch**: Service file referenced wrong config file name
3. **Database Corruption**: Corrupted `DATABASE_METADATA.json` file preventing startup
4. **Missing Required Files**: Genesis, static-nodes, and permissions files in wrong locations
5. **Database Directory Missing**: `/data/besu/database/` directory did not exist

---

## ✅ Resolution Steps Taken

### 1. Configuration File Fix

**Problem**: Service expected `config-rpc.toml` but only `config-rpc-public.toml` existed

**Solution**:
```bash
pct exec 2500 -- cp /etc/besu/config-rpc-public.toml /etc/besu/config-rpc.toml
pct exec 2500 -- chown besu:besu /etc/besu/config-rpc.toml
```

### 2. Service File Update

**Problem**: Service file referenced `config-rpc-public.toml` instead of `config-rpc.toml`

**Solution**:
```bash
pct exec 2500 -- sed -i 's|config-rpc-public.toml|config-rpc.toml|g' /etc/systemd/system/besu-rpc.service
pct exec 2500 -- systemctl daemon-reload
```

### 3. Database Corruption Fix

**Problem**: Corrupted `DATABASE_METADATA.json` causing startup failures

**Solution**:
```bash
pct exec 2500 -- systemctl stop besu-rpc.service
pct exec 2500 -- rm -f /data/besu/DATABASE_METADATA.json
pct exec 2500 -- rm -rf /data/besu/database/*
```

### 4. Required Files Setup

**Problem**: Genesis, static-nodes, and permissions files in `/etc/besu/` but config expects `/genesis/` and `/permissions/`

**Solution**:
```bash
# Create directories
pct exec 2500 -- mkdir -p /genesis /permissions

# Copy files
pct exec 2500 -- cp /etc/besu/genesis.json /genesis/
pct exec 2500 -- cp /etc/besu/static-nodes.json /genesis/
pct exec 2500 -- cp /etc/besu/permissions-nodes.toml /permissions/

# Set ownership
pct exec 2500 -- chown -R besu:besu /genesis /permissions
```

### 5. Database Directory Creation

**Problem**: Database directory missing

**Solution**:
```bash
pct exec 2500 -- mkdir -p /data/besu/database
pct exec 2500 -- chown -R besu:besu /data/besu
```

### 6. Service Restart

**Solution**:
```bash
pct exec 2500 -- systemctl start besu-rpc.service
```
