Proxmox HA need to know


Although the Proxmox High Availability feature is a great addition to a virtual cluster environment, there are few things you will have to keep in mind while implementing this feature.

If a Proxmox HA node needs a reboot due to a kernel update or anything else, then the rgmanager program must first be stopped on the node before rebooting. It can be stopped through the CLI. The command usually takes a while to complete. Always monitor the Task Log from the GUI. When the rgmanager program is stopped, reboot the node. To stop the rgmanager program, use the following command:

# /etc/init.d/rgmanager stop

Note

The rgmanager or resource group manager program manages High Availability resources such as cluster services to provide failover abilities. During a node failure, rgmanager relocates cluster-specific services to different nodes with minimal interruption.
