Increasing storage capacity - FSx for Lustre
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Increasing storage capacity

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

To increase storage capacity for a file system (console)

  1. Open the Amazon FSx console at https://console.amazonaws.cn/fsx/.

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

  3. 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.

  4. 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 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 MB/s/TiB file systems and multiples of 1800 GiB for 40 MB/s/TiB file systems.

  5. Choose Update to initiate the storage capacity update.

  6. 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 Amazon CLI command update-file-system. 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 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 MB/s/TiB file systems and multiples of 1800 for 40 MB/s/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 file system.

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

  2. You can monitor the progress of the update by using the Amazon CLI command describe-file-systems. Look for the administrative-actions in the output.
