LiveNX 25.2.0 New Features : Server High Availability
Server High Availability
Overview
LiveNX 25.2.0 adds a basic High Availability service to the LiveNX Server only, allowing a customer to sync Server state and settings from a “Primary” Server to a “Secondary” Server. The Secondary Server will not be running LiveNX processes until the customer manually promotes it to Primary Server.
Limitations
Data loss from a Node failure is not prevented
There are no alerts on failure of Primary Server
There are no alerts if sync stops working
Data loss due to human error or corruption is not prevented
NFS filesystems
Warnings
It is possible that the synced configuration could be in a corrupt state at sync time. The Secondary Server is not guaranteed to work when promoted.
When promoting the Secondary Server to Primary Server, Customer will be required to manually change the IP of the Secondary Server to the IP of the Primary Server. This requires deploying them in the same subnet.
A license is not required to run HA sync. If a customer has a failure but has not acquired a license for the secondary server, LiveNX support turnaround time will affect how quickly they are back in normal operating mode.
