Technical Tip: Extending disk space

[heng]

Description

This describes explains how to add new virtual disks to extend the disk space in FortiMail VM.

Scope

FortiMail.

Solution

1. Before extending the disk space, run the command 'get sys status' to check the current size of the FortiMail VM hard disk.

get sys status
Version:         FortiMail-VM v6.4.3(GA), build437, 2020.10.15
Architecture:              64-bit
Serial-Number:          FEVM320000210901
BIOS version:            n/a
VM Registration:      Valid: License has been successfully authenticated with registration servers.
VM License File:      License file and resources are valid.
VM Resources:         1 CPU/32 allowed, 2003 MB RAM/131072 MB allowed, 249 GB Disk/24576 GB allowed
Log disk:                  Capacity 49 GB, Used 32 MB (0.07%), Free 49 GB
Mailbox disk:          Capacity 198 GB, Used 309 MB (0.16%), Free 198 GB

2. From the output above, FortiMail VM has 250GB hard disk.

Note.
Make sure the VM license can support the hard disk volume after extending the hard disk. For this example, the VM license is able to support up to 24576 GB.

3. Backup the current configuration and all necessary data before proceeding. If the intention is to resize the log disk, it is necessary to backup all logs in an eternal Syslog server. These logs cannot be restored after the procedure so the logs could be lost.
4. Shut down the Fortimail VM and add a new virtual disk of 200GB to FortiMail.
   

5. After that, power on the FortiMail VM.
6. Run the following command in FortiMail VM.

exe lvm enable

LVM is already enabled in this device
exe lvm extend

This will stop all mail services and then extend log and spool devices, are you sure (Y/N)?y
Fortimail will REBOOT !!

7. The FortiMail hard disk is successfully extended to 450 GB.
