Technical Tip: How to repair or format logdisk if status shows not available

Description

This article describes how to repair or format logdisk if the status shows not available.

Scope

FortiWeb.

Solution

From CLI, check the sessions using the following commands:

diagnose system mount list

Check for var/log, which is not showing in this case in the output below.

Try to repair the log disk by below command:

FortiWeb-A # execute fscklogdisk

Try to rebuild the database using the following command:

 FortiWeb-A # execute db rebuild

If this resolves the issue and shows var/log and log disk as available, otherwise log disk needs to be formatted by the following command:
Note: This command will delete logs on FortiWeb, and as of version 7.2.1, will lead to rebooting FortiWeb (a maintenance window is required as a reboot will be triggered, causing service interruption):

FortiWeb-A # execute formatlogdisk

When executing this command, the FortiWeb appliance displays the following message:

This operation will clear all data on the log disk and take a few minutes according to the disk size!!
Do you want to continue? (y/n)
Enter 'y' to continue. Enter 'n' if you want to abort the operation.

Output post fscklogdisk command.
