- Enter the command below in the CLI to identify the partition path that is facing the issue:
# fn df -h
Filesystem Size Used Available Use% Mounted on
/dev/root 835.7M 740.0M 95.7M 89% /
none 1.1G 32.1M 1.1G 3% /tmp
none 3.8G 3.8M 3.8G 0% /dev/shm
/dev/sda1 362.1M 361.2M 0 100% /data <- The path facing the issue is /data.
/dev/sda3 90.5M 28.0K 85.6M 0% /home
/dev/sda4 30.4G 707.4M 28.2G 2% /var/log
- Enable shell access using CLI:
For versions older than v7.6.x:
config system global
set shell-access enable
set shell-username shell
set shell-password fortinet
set shell-timeout 1200
end
For v7.6.x:
config system console
set shell sh
end
- Access shell:
For versions older than v7.6.x:
Log in using the CLI using the credentials set in the previous step:
- username: shell
- password: fortinet
For v7.6.x:
Connect to the console and enter the exit command to quit the CLI and access shell.
- Run the command in the required partition and collect the output for analysis:
du -a <path> | sort -rn | head -n 100
Example with partial output:
du -a /data | sort -rn | head -n 100
