Description
This article describes how to extend log disk FortiGate running on VM ESXi.
Scope
FortiGate.
Solution
In the previous version, there was an option to add a new virtual disk, format it, and use it as another log disk. In the current version release, there is a change in behavior.
When a new virtual disk is added on FortiGate VM and formatted, it will then be partitioned into 3 parts and can only be used as WAN Optimization Storage.

The only officially supported way to extend the log disk is by redeploying the VM with a larger disk size or a larger virtual disk size can be assigned to the VM, but need to format the log disk.
exec formatlogdisk
Any other methods used to extend the log disk and issues caused as a consequence will not be supported by the Fortinet support team.
