[linux-lvm] Post-install LVM

[rodrigo tavares]

Hello,

I have a Installed my Linux, with support LVM.
When I run command gvdisplay. 
Look Free Pe equal 0.
When i try run command:

lvextend -L+99G /dev/mailx/mailx
Extending logical volume mailx to 185,24 GiB
Insufficient free space: 25344 extents needed, but only 0 available
I think the value in "Free  PE / Size" may be not 0. 

How I can to set any value in "Pe / size" ?
So getting add new volumes.
