[application]*Anaconda* uses an opposite approach. First, you create all separate mount points you need, and everything needed to create them (creating a volume group, logical volumes inside it, and physical volumes where the volume group will reside) is performed automatically. You can then adjust the automatic settings as you require.
Click the `+` button to add a mount point. In the dialog window that opens, choose a mount point such as `/` or `/home`, and the desired capacity for the mount point (such as `10GB` or `500MB`). Note that specifying the mount point is mandatory, but you do not have to specify the capacity at this point; this is useful when adding a mount point which you want to make larger than the current available space permits. Then, click `Add mount point` to add it to the list using the default settings, which means it will be created as a logical volume, and a new volume group will be created for it unless one already exists.
