To increase the storage capacity for an FSx for Windows File Server file system, use the AWS CLI command [update-file-system](https://docs.aws.amazon.com/cli/latest/reference/fsx/update-file-system.html). Set the following parameters:
+ `--file-system-id` to the ID of the file system you are updating.
+ `--storage-capacity` to a value that is at least 10 percent greater than the current value.

You can monitor the progress of the update by using the AWS CLI command [describe-file-systems](https://docs.aws.amazon.com/cli/latest/reference/fsx/describe-file-systems.html). Look for the `administrative-actions` in the output. 

For more information, see [AdministrativeAction](https://docs.aws.amazon.com/fsx/latest/APIReference/API_AdministrativeAction.html).
