This topic describes how to resize a system disk. A system disk created from an image is limited to the size of the image, but can be resized after the disk is created.
For example, you want to create a 100 GB Linux system disk to host your services. However, the image is only 20 GB in size. This results in a system disk size of 20 GB, which is insufficient for your use case. If you do not resize the system disk, your services may be affected.
