I have been using 70GB of the 100GB in my DreamCompute instance for about 15 months. I would like to create an additional (new) volume using the remaining 30GB I am paying for, and attach is to the CentOS7 system running in the 70GB volume. Since I am still learning how to navigate and manage DreamCompute, I think I better ask for help.
What are the steps to create and attach the reamaining 30GB space to the CentOS7 system in the first volume? If there is a help tutorial already prepared on this topic, please point me to it. Thank you in advance for your assistance.
