NOTE: To fully apply your upgrade, first shut down your OS, power off the server from the Control Panel, and then power it back on through the Control Panel. This process ensures the system recognizes the updated drive specifications.Keep in mind, the additional space will remain unavailable until you resize your disk or partition. Do not format the existing volume when your intention is to extend it.
