[ovirt-users] How to increase the total space of storage domain

Hi: In the management page of the web, the total space of the domain added to the storage domain page cannot specify a specific value. The total space value is determined by a specific code function based on the configuration parameters of the physical machine, or is it a fixed value？ Is there any way to modify this value? After I create multiple virtual machines, this space is not enough to continue to create virtual machines. How can I solve this problem? Thank you.
