Proxmox Clustering Technology

Introduction

• Demonstration using a home lab environment.
• Successfully completed live migration of Lubuntu 24.04.
• Minimal packet loss experienced, likely due to internet issues.

Simulating Host Failure

• Current Setup:
  • Lubuntu moved from PVE1 to PVE2.
  • Cluster originally built on PVE1.
• Simulated Failure:
  • Turned off PVE1 to simulate failure.
  • PVE2 detected PVE1 offline.
  • Cluster (PVECL1) still operational with PVE2.
• Effect of Failure:
  • Operations on PVE1 affected, but overall cluster continues to function.
  • Improvement over other technologies with central control node dependency.

Restoration of Service

• PVE1 restarted, and system quickly returns to normal operation.
• Raspberry Pi Desktop VM did not auto-start but can be configured.

Disk Image Handling in Proxmox

• Current Limitation:
  • Local storage for ISO images is restricted.
  • PVE1 has ISO images; PVE2 does not.
  • No access to ISO images on PVE2 when trying to connect to Lubuntu 24.04.
• Migration Issues:
  • ISO images linked to local storage prevent migration.
  • Solution: Disconnect ISOs or physical media before migration.
  • Set VM to "Do not use any media" to enable migration.

Shared Storage Solutions

• Exploring solutions for shared storage of ISOs (e.g., NFS).
• Requires more research for effective configuration.

Conclusion

• Proxmox offers an improved clustering solution.
• Future videos will explore shared storage options further.
