Disk Layout

nvme0n1 (931.5 GB):
├─ nvme0n1p1: 1007K (BIOS Boot)
├─ nvme0n1p2: 1G (EFI System)
└─ nvme0n1p3: 930G (ZFS - rpool)

nvme1n1 (931.5 GB):
├─ nvme1n1p1: 1007K (BIOS Boot)
├─ nvme1n1p2: 1G (EFI System)
└─ nvme1n1p3: 930G (ZFS - rpool mirror)

nvme2n1 (7.5 TB):
└─ Entire disk: ZFS - storage-vm-zrh-v1

ZFS Pool Creation (VM Storage)

# On srv-pve-zrh-01
zpool create \
  -o ashift=12 \
  -O atime=off \
  -O compression=lz4 \
  -O relatime=on \
  storage-vm-zrh-v1 \
  /dev/nvme2n1

# Add to Proxmox
pvesm add zfspool storage-vm-zrh-v1 \
  --pool storage-vm-zrh-v1 \
  --content images,rootdir \
  --nodes srv-pve-zrh-01

Repeat on srv-pve-zrh-02.

ZFS Status Commands

# Pool status
zpool status storage-vm-zrh-v1
zpool list storage-vm-zrh-v1

# Proxmox storage status
pvesm status

# IO stats
zpool iostat -v storage-vm-zrh-v1 1

Replication (between nodes)

Configure in Proxmox Web UI:

Datacenter → Replication → Add
- VM/CT: Select VM
- Target: srv-pve-zrh-02
- Schedule: */15 (every 15 minutes)

Future: Ceph (Planned)

Ceph is planned but not yet implemented. Requirements:

• Additional NVMe SSDs for Ceph OSD
• Minimum 3 OSDs recommended (2 possible with reduced redundancy)
• Will use bond1 (25G Storage Network)
