Actions Taken: Upgraded Proxmox VE (PVE) to the latest stable release (kernel & security patches) and adjusted compute resources (vCPU, RAM, Storage) for designated VMs/LXCs.

Current State: Hypervisor node is stable, resource allocations are optimized, and all services are verified UP via live monitoring (Grafana/Uptime Kuma). No issues or rollbacks required.

Activity: Major Upgrade Proxmox VE (PVE) & Compute Resource Optimization (vCPU, RAM, Storage).

Objective: Patch security vulnerabilities, improve hardware driver stability, and optimize VM/LXC allocations based on performance metrics to eliminate bottlenecks.

Impact: Total Downtime during the hypervisor reboot and brief service interruptions during individual VM/LXC restarts.

Rollback Plan: GRUB boot to the previous stable kernel or full restore from the latest pre-maintenance snapshots if critical failure occurs.
