FortiAnalyzer VM Growing Disk Space

[Travis]

I was running out of disk space on my FortiAnalyzer VM, so my VM Admin doubled up the space.  I did a reboot and it did not see the increase, so I upgraded it to 5.0.10, and it still does not see the increase in space.  

What do I need to do for it to recognize the expanded disk space?

Thank all of you for any assistance!

Based on my experience with Fortinet support, you will need to reformat your disk for the FAZ to recognize the new space.  

It would be better to just add a second disk to your FAZ and then you can "extend" your disk space which basically just means the FAZ sees the two disks as one.  It would appear as though you can do this with up to 8 disks total.

If you have to format the disk you can so by running "execute format disk" but be aware of the repercussions.

If you want to extend your storage into a second disk:

1.  Verify LVM is started - "execute LVM start"

2.  See if second disk is recognized - "execute lvm info"

3.  Extend storage - "execute lvm extend diskXX"

4.  Rebuild DB after reboot "execute sql-local rebuild-db"

Hello bhwong,

You need to format your disk , 

check  execute lvm info  on your FAZ 

if you increase the current disk,  the FMG/FAZ VM says the extra space cannot be used unless  format performs. 

I would suggest you go over these carefully: VM Installation Guide

Thank you both!

The link and for the steps.

I looked in KB for an answer but did not find that document..

Expansion has been completed and my Boss will be happy.

There were two solutions posted above which I believe the OP used to fix his issue.  Is there something more specific you are looking for?

[Yanis_Sauve]

Not really...

His post appeared to say he did not find a solution in the KB, and simply said the job was done.

I personnaly used the KB article to add a disk to my FAZ-VM...

I only wanted to suggest he posts his solution for the benefit of others. I probably did not fully understand the meaning of his post. :)

Instead of adding a new disk, I increase the capacity of the existing disk. Is it possible to extend the existing disk capacity in FAZ?

Thanks! After I expand the disk and realise that the recommended method is to add new disk instead of expanding existing disk, I have to edit the vmx file to shrink the disk back to it's original size, as the vSphere web client only allow me to expand but not shrink, despite I have not expand the capacity in the OS yet.

I have proceed with adding a new disk of 170GB to my existing 30GB disk (with 8GB as the OS and boot disk). However, I'm surprise that after LVM combine the two disks (30GB + 170GB), the total capacity shown is 150GB instead of 200GB. Why is this so?

If I want to maximise my licensed 200GB, should I add another disk with 50GB capacity? Or I have to take the 1/4 lost of capacity in LVM into account by adding a 67GB disk instead, in order to achieve 200GB total capacity?
