- Proxmox Snapshots: How They Work and When to UseHow Proxmox VE snapshots work on each storage type, what the vmstate option really saves, why rollback is one-way, and when a snapshot is not a safety net.
- Proxmox Ceph vs ZFS Replication: When Ceph Is Worth ItWhen Ceph beats ZFS replication on Proxmox VE, the real node and network minimums, the hardware that actually works, and the operational cost you take on.
- Proxmox ZFS Storage: Pools, Zvols, volblocksize, ARCHow to run Proxmox VE on ZFS: root-on-ZFS layout, zvol-backed VM disks, why volblocksize is set once, and sizing ARC when guests need the RAM.
virtualization 3 posts
- Proxmox GPU Passthrough: IOMMU, VFIO, and the AMD Reset BugHow to pass a GPU through to a Proxmox VE guest: IOMMU groups, VFIO binding, the AMD vendor-reset problem, and where passthrough actually breaks.
- Proxmox LXC vs VM: Which One Should You Use?LXC containers or KVM virtual machines on Proxmox VE? A guide to overhead, isolation, privileged vs unprivileged, and when passthrough forces a VM.
- Proxmox VE vs TrueNAS SCALE: Which Should Be the Host?Proxmox VE vs TrueNAS SCALE: which one belongs on bare metal, when to run TrueNAS as a Proxmox VM, and why HBA passthrough is non-negotiable.
backup 2 posts
- Proxmox Backup Strategy: vzdump, Retention & OffsiteBuild a Proxmox backup plan with vzdump modes, guest consistency, retention schedules, offsite copies, host configuration backups, and restore tests.
- Proxmox Backup Server Setup: Dedup, Prune, and RestoresHow to set up Proxmox Backup Server: how chunk deduplication works, why it beats vzdump, prune and GC scheduling, and how to verify restores.
clustering 2 posts
- Proxmox Cluster Setup: Corosync, Quorum, and QDeviceBuild a Proxmox VE cluster that stays quorate: how Corosync works, why two nodes is a trap, when to add a QDevice, and the network a cluster needs.
- Proxmox High Availability: Fencing, HA Rules, and LimitsHow Proxmox VE HA works: the CRM and LRM, node affinity rules and priorities, watchdog fencing, shared storage requirements, and what HA cannot save.
networking 2 posts
- Proxmox Ports: Which Ones to Open, and for WhatEvery port Proxmox VE listens on: the 8006 web GUI, console and SPICE, corosync 5405-5412, migration 60000-60050, plus Ceph and Backup Server.
- Proxmox Network Bridges and VLANs: vmbr0, Tags, and OVSHow Proxmox VE networking works: Linux bridge vs Open vSwitch, VLAN-aware bridges, tagging guests, and applying changes without locking yourself out.
