How to Check Cluster Health and Quorum Status in Proxmox VE (pvecm status Explained)
Learn what quorum means in a Proxmox VE cluster, how to read pvecm status and pvecm nodes output, and how to recover a cluster that's stuck read-only after losing quorum.
How to Set Up an SDN VLAN Zone in Proxmox VE (Manage VLANs Across a Whole Cluster)
Define your VLANs once in Proxmox VE SDN instead of configuring them by hand on every node. This beginner guide walks through creating a VLAN zone, adding VNets, applying the config, and attaching VMs.
How to Migrate an LXC Container Between Nodes in a Proxmox VE Cluster
Learn how to move a running or stopped LXC container between nodes in a Proxmox VE cluster using pct migrate, why containers can't truly live-migrate like VMs, and how to fix the local bind mount error that blocks most migrations.
How to Create a Proxmox VE Cluster and Add Nodes (Step-by-Step Guide for Beginners)
Ready to move past a single Proxmox box? Here is how to actually create a cluster, join a second node, and confirm quorum is working, using both the web GUI and pvecm from the shell.
How to Fix Time Zone and NTP Sync Problems in Proxmox VE (Chrony, timedatectl, and Clock Drift)
Proxmox VE relies on an accurate clock for cluster quorum, TLS certificates, and backup schedules. Here's how to check your sync status, set the right time zone, and fix chrony NTP problems step by step.
How to Enable and Configure the Cluster Resource Scheduler (CRS) for Automatic Load Balancing in Proxmox VE
A practical guide to Proxmox VE's Cluster Resource Scheduler: the basic, static, and dynamic scheduling modes, how to turn on automatic load-based rebalancing, and how to tune the threshold, margin, and hold-duration settings so it doesn't thrash your cluster.
How to Set Up Storage Replication Between Proxmox VE Nodes (ZFS-Based, No Shared Storage Required)
Configure ZFS-based storage replication between Proxmox VE nodes from scratch using the GUI and the pvesr CLI — schedules, bandwidth limits, and how it pairs with HA for fast failover without a SAN.
How to Deploy a Kubernetes Cluster on Proxmox VE Using Talos Linux
A complete walkthrough for running a production-style Kubernetes cluster on Proxmox VE using Talos Linux — an immutable, API-managed OS built solely for Kubernetes. Covers the Image Factory, correct VM hardware settings (CPU type, virtio, guest agent), generating and applying machine configs, bootstrapping etcd, scalin
How to Configure High Availability (HA) for VMs and Containers in Proxmox VE
A hands-on guide to building real HA in Proxmox VE: enabling ha-manager on VMs and containers, controlling placement with node and resource affinity rules, tuning restart/relocation limits, and testing failover before you trust it.
