Use the entire disk with LVM so that it is easy to expand later.

with the following recipe:

Choose Manual Partitioning
Choose Virtual disk 1
Yes to Create an empty partition table on this device
Select the Free Space
Create a new partition
Use the whole space. OTOH, if you will be creating many partitions and you may later wish to expand one of them, leave some space for that future expansion
Type of the new partition is Primary
Use as Physical volume for LVM
Done setting up the partition
Configure the Logical Volume Manager
Yes, Write the changes to disk
Create volume group
Name it as you wish. In this case, I used bro1-vg.
Select the device for the VG, normally /dev/vda1
Create logical volume, in the VG you just created
As I was building a single file system server, I named it 'root'.
Give it the whole partition. Or you can leave room for a swap partiton
If you want to also make a swap filesystem,
- Create another logical volume
- Name it 'swap'
- Give it the rest of the space
Finish
Select the #1 partition under the LVM VG you ust created
Use as Ext4
Mount point /
Label 'root'
Done setting up the partition
Finish partitioning and write changes to disk
