Configuring Node Time Synchronization in a Proxmox VE Cluster
December 24, 2025
Step 1: Configure time synchronization within the cluster (recommended for offline environments) If the external NTP source is unstable, designate one node as the “time master node” and have the other nodes synchronize with it, ensuring strict time consistency across the cluster: 1. Choose one node as the time master (e.g., pve01, IP: 192.168.20.101) bash Run # On the master node, edit chrony.conf to allow access from the cluster subnet vim /etc/chrony/chrony.conf # Add the following (adjust the cluster subnet
