Proxmox ZFS Storage Setup#

What Was Established#

Procedures for initializing ZFS pools using multiple drives via the Proxmox Web GUI and configuring them as usable storage for Virtual Machines (VMs) and Linux Containers (LXC).

Key Decisions#

• RAID Levels: Selection depends on the number of disks and redundancy requirements:
  • Stripe (RAID 0): Maximum capacity, no redundancy.
  • Mirror (RAID 1): Redundancy, 50% capacity loss.
  • RAID-Z1/Z2: Requires 3+ disks for parity-based redundancy.
• Compression: lz4 is the recommended compression algorithm for performance.
• Ashift: Set to 12 for modern SSDs/NVMe to ensure proper block alignment.
• Thin Provisioning: Enabled for storage pools to allow for flexible disk allocation.

Current Configuration#

1. Initialize ZFS Pools (Web GUI)#

Navigate to: Datacenter → Node → Disks → ZFS
