I create new virtual machine in OpenStack Project.
After I want to add size free space in VM.
I added new Volume and attached to VM.
After start VM I tryed to check status HDD.
fdisk -l

Welcome to fdisk (util-linux 2.23.2). Changes will remain in memory only, until you decide to write them. Be careful before using the write command.
