# Increasing storage capacity
<a name="increase-storage-capacity"></a>

You can increase a file system's storage capacity using the Amazon FSx console, the AWS CLI, or the Amazon FSx API.

**To increase storage capacity for a file system (console)**

1. Open the Amazon FSx console at [https://console.aws.amazon.com/fsx/](https://console.aws.amazon.com/fsx/).

1. Navigate to **File systems**, and choose the Lustre file system that you want to increase storage capacity for.

1. For **Actions**, choose **Update storage capacity**. Or, in the **Summary** panel, choose **Update** next to the file system's **Storage capacity** to display the **Increase storage capacity** dialog box.

1. For **Desired storage capacity**, provide a new storage capacity in GiB that is greater than the current storage capacity of the file system:
   + For a persistent SSD or scratch 2 file system, this value must be in multiples of 2400 GiB.
   + For a persistent HDD file system, this value must be in multiples of 6000 GiB for 12 MBps/TiB file systems and multiples of 1800 GiB for 40 MBps/TiB file systems.
   + For an EFA-enabled file system, this value must be in multiples of 38400 GiB for 125 MBps/TiB file systems, multiples of 19200 GiB for 250 MBps/TiB file systems, multiples of 9600 GiB for 500 MBps/TiB file systems, and multiples of 4800 GiB for 1000 MBps/TiB file systems.
**Note**  
You cannot increase the storage capacity of scratch 1 file systems.

1. Choose **Update** to initiate the storage capacity update.

1. You can monitor the update progress on the file systems detail page in the **Updates** tab.

**To increase storage capacity for a file system (CLI)**

1. To increase the storage capacity for an FSx for Lustre 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:

   Set `--file-system-id` to the ID of the file system you are updating.

   Set `--storage-capacity` to an integer value that is the amount, in GiB, of the storage capacity increase. For a persistent SSD or scratch 2 file system, this value must be in multiples of 2400. For a persistent HDD file system, this value must be in multiples of 6000 for 12 MBps/TiB file systems and multiples of 1800 for 40 MBps/TiB file systems. The new target value must be greater than the current storage capacity of the file system.

   This command specifies a storage capacity target value of 9600 GiB for a persistent SSD or scratch 2 file system.

   ```
   $ aws fsx update-file-system \
       --file-system-id fs-0123456789abcdef0 \
       --storage-capacity 9600
   ```

1. 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.
