Expanding a volume in Failover Cluster Manager involves a few steps. Here is a general overview of the process:
- Open Failover Cluster Manager by searching for it in the Start menu or by running “cluadmin.msc” in the command prompt.
- In the left pane, select the cluster you want to work with. In the center pane, click on the “Storage” option.
- Select the volume you want to expand and right-click on it. Choose the “Expand” option from the context menu.
- In the “Expand Volume” wizard, you will be prompted to select the disk you want to use to expand the volume. Select the disk and click “Next”.
- In the next step, you can specify the amount of space you want to add to the volume. The maximum amount of space available for expansion will be displayed.
- Once you have specified the amount of space, click “Next” and review the summary of the changes.
- Click “Finish” to begin the expansion process. This may take some time, depending on the size of the volume and the amount of space being added.
- Once the process is complete, the volume will be expanded, and the new space will be available for use.
Note: The steps may vary slightly depending on the version of Failover Cluster Manager you are using and the configuration of your cluster. It is always recommended to have a full backup of your data before starting the expansion process.
Also, if the volume is a dynamic disk, it can be expanded online and the process will not require any downtime. But in case of a basic disk, it will require the volume to be taken offline, and the expansion process will require downtime.
