An EVS system disk can be as large as 1 TiB (1,024 GiB). You can expand the capacity of a system disk to up to 1 TiB.
In this case, if you want to expand the disk capacity to over 2 TiB, change the partition style from MBR to GPT. Ensure that the disk data has been backed up before changing the partition style because services will be interrupted and data on the disk will be deleted during this change.
