Description |
This article describes how to work around a situation where the FortiGate Cluster upgrade gets stuck and only one member of the cluster has upgraded. |
Scope | FortiGate cluster upgrade. |
Solution |
For example: One member is on v7.2.2 (usually the Active unit) and the other is on v7.2.3 (usually the backup).
Schedule a maintenance window before proceeding and download the FortiOS 7.2.3 image file for the unit affected from the Fortinet support website.
From here, proceed in one of two ways:
Scenario 1: If the Active unit is running v7.2.3, retry the upgrade by using the downloaded FortiOS image.
Scenario 2: If the Active unit is the one still in 7.2.2, either perform a failover or perform the following steps:
Example upgrading from v7.4.4 to v7.6.0:
If the upload is started on the Passive member, a known issue in v7.2 may occur that invalidates the image. If it is not possible to downgrade because a VM is being used, try to stop the 'Fabric Upgrade' and proceed directly with the 'Upgrade' button. |
