# Pre-Start Checklist - Hostnames and IP Addresses
|
|
|
|
**Date:** 2025-01-20
|
|
**Purpose:** Complete audit and fixes before starting VMs on pve and pve2
|
|
|
|

|
|
|
|
## ✅ IP Address Audit - COMPLETE
|
|
|
|
**Status:** All IPs audited, no conflicts found
|
|
|
|
**Results:**
|
|
- All 34 VMs/containers are currently on **ml110** (192.168.11.10)
|
|
- **pve** (192.168.11.11) and **pve2** (192.168.11.12) have no VMs/containers yet
|
|
- **No IP conflicts detected** across all hosts
|
|
- **No invalid IPs** (network/broadcast addresses)
|
|
|
|
**Allocated IPs (34 total):**
|
|
- 192.168.11.57, .60-.64, .80, .100-.106, .112, .120, .130, .150-.156, .201-.204, .240-.242, .250-.254

## ⏳ Hostname Migration - PENDING
|
|
|
|
### Current State
|
|
- **pve** (192.168.11.11) - hostname: `pve`, should be: `r630-01`
|
|
- **pve2** (192.168.11.12) - hostname: `pve2`, should be: `r630-02`
|
|
|
|
### Migration Steps
|
|
|
|
**Script Available:** `scripts/migrate-hostnames-proxmox.sh`
|
|
|
|
**What it does:**
|
|
1. Updates `/etc/hostname` on both hosts
|
|
2. Updates `/etc/hosts` to ensure proper resolution
|
|
3. Restarts Proxmox services
|
|
4. Verifies hostname changes
|
|
|
|
**To execute:**
|
|
```bash
|
|
cd /home/intlc/projects/proxmox
|
|
./scripts/migrate-hostnames-proxmox.sh
|
|
```
|
|
|
|
**Manual steps (if script fails):**
|
|
```bash
|
|
# On pve (192.168.11.11)
|
|
ssh root@192.168.11.11
|
|
hostnamectl set-hostname r630-01
|
|
echo "r630-01" > /etc/hostname
|
|
# Update /etc/hosts to include: 192.168.11.11 r630-01 r630-01.sankofa.nexus pve pve.sankofa.nexus
|
|
systemctl restart pve-cluster pvestatd pvedaemon pveproxy
|
|
|
|
# On pve2 (192.168.11.12)
|
|
ssh root@192.168.11.12
|
|
hostnamectl set-hostname r630-02
|
|
echo "r630-02" > /etc/hostname
|
|
# Update /etc/hosts to include: 192.168.11.12 r630-02 r630-02.sankofa.nexus pve2 pve2.sankofa.nexus
|
|
systemctl restart pve-cluster pvestatd pvedaemon pveproxy
|
|
```
|
|
|

|
|
## Verification Steps
|
|
|
|
### 1. Verify Hostnames
|
|
```bash
|
|
ssh root@192.168.11.11 "hostname" # Should return: r630-01
|
|
ssh root@192.168.11.12 "hostname" # Should return: r630-02
|
|
```
|
|
|
|
### 2. Verify IP Resolution
|
|
```bash
|
|
ssh root@192.168.11.11 "getent hosts r630-01" # Should return: 192.168.11.11
|
|
ssh root@192.168.11.12 "getent hosts r630-02" # Should return: 192.168.11.12
|
|
```
|
|
|
|
### 3. Verify Proxmox Services
|
|
```bash
|
|
ssh root@192.168.11.11 "systemctl status pve-cluster pveproxy | grep Active"
|
|
ssh root@192.168.11.12 "systemctl status pve-cluster pveproxy | grep Active"
|
|
```
|
|
|
|
### 4. Re-run IP Audit
|
|
```bash
|
|
./scripts/check-all-vm-ips.sh
|
|
```
|
|
|
