Formating logdisk will make FGT to use the whole space. Havent tried it but other engineers have tested that it works.

Please try commands described in this link:

But most probably this will come to help:

thanks @xshkurti 
My total 2 disk space is 100GB (20+80), I curious about my Virtual-Disk(80.0GiB) how many disks space in-used because it not show the total (80Gb) when running "fnsysctl df -h"
Or can any command show how many disks space was used in 100GB allocated?

I think we have the solution here.
You have a 80GB HDD but you are using only:
set size 30107 (29.4GB)
In order for you to use the whole HDD you have to change
config system storage

edit "Virtual-Disk"
set size 81920 
next

end

After this change you will use all 80 GB and see correct values.

I see the problem!
But can I set the size 30Gb to 80Gb on Fortigate, can you show me?
There is no command to set the size to 81920 as your comment above.
