Expanding a Volume on the ztC Edge System
Expand a virtual machine (VM) volume to allocate more space for programs and data in the guest operating system.
You can expand a volume, but you cannot reduce the size of a volume. Use the following procedure to expand a volume only when the VM is stopped.
Prerequisites:
- You must shut down the VM before expanding a volume that it contains.
- Ensure that both PMs of the ztC Edge system are online; otherwise, the system cannot properly expand a volume.
To expand a volume
-
On the Physical Machines page (see The Physical Machines Page) of a system licensed for two nodes, verify that both PMs are in the running state and that neither PM is in maintenance mode or in the process of synchronizing.
- On the Virtual Machines page (see The Virtual Machines Page), select the VM that contains the volume that you want to expand. Ensure that the VM is stopped.
- In the bottom pane, click the Volumes tab and select the volume that you want to expand. In the Action column, click Expand Volume.
-
Next to Expand By, type the amount of storage space to add to the volume (in gigabytes (GB)). When you type the number, the dialog box displays the Expanded Volume Size that will result if you complete the operation.
Note: Consider the Expand By entry carefully, because after expanding a volume, you cannot undo the change or reduce the size of the volume; you can only expand the volume further.
- Click Expand Volume to commit the change and expand the volume. The dialog box displays the expansion progress and automatically closes when the operation is complete.
