Question

FortiNac Stable Version?

We are experiencing persistent database replication failures across our HA cluster and are looking for advice on the most stable release train before we perform a clean rebuild.

Timeline:

  1. v7.6.6: Initial deployment worked for several weeks, but we eventually started encountering internal database errors whenever we tried adding new network switches.

  2. v7.6.7: Upgraded to address the switch-addition errors. The upgrade broke High Availability database replication completely between the primary and secondary nodes.

  3. STS Release: TAC advised upgrading to the Short-Term Support (STS) release, but HA database replication remains broken.

 

Which version/release train is currently the most stable for FortiNAC-F running HA, 802.1X, and EDR? Is the 7.4.x train the recommended target for production HA stability right now?

The 7.4 seems to work well. However, the 7.6 would be recommended for new deployments. The 7.6.7 added a migration for RADIUS-only devices. That migration might be causing a headache:

Deploying on 7.6.7/STS might be a good choice or 7.6.8 when it comes.

Best regards, Markus
