Monitoring volume storage capacity - FSx for ONTAP
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).

Monitoring volume storage capacity

You can view a volume's available storage and it's storage distribution in Amazon Web Services Management Console, Amazon CLI, and the NetApp ONTAP CLI.

To monitor a volume's storage capacity (console)

The Available storage graph displays the amount of free storage capacity on a volume over time. The Storage distribution graph shows how a volume's storage capacity is currently distributed over 4 categories:

  • User data

  • Snapshot data

  • Available volume capacity

  • Other data

  1. Open the Amazon FSx console at

  2. Choose Volumes in the left navigation column, then choose the ONTAP volume that you want to view storage capacity information for. The volume detail page appears.

  3. In the second panel, choose the Monitoring tab. The Available storage and Storage distribution graphs display, along with several other graphs.

    A volume's Available storage graph in the Monitoring tab, as seen in the Amazon FSx console.

To monitor a volume's storage capacity (ONTAP CLI)

You can monitor how your volume's storage capacity is being consumed by using the volume show-space ONTAP CLI command. For more information, see volume show-space in the NetApp ONTAP Documentation Center.

  1. To access the NetApp ONTAP CLI, establish an SSH session on the management port of the Amazon FSx for NetApp ONTAP file system by running the following command. Replace management_endpoint_ip with the IP address of the file system's management port.

    [~]$ ssh fsxadmin@management_endpoint_ip

    For more information, see Managing file systems with the ONTAP CLI.

  2. View a volume's storage capacity usage by issuing the following command, replacing the following values:

    • Replace svm_name with the name of the SVM that the volume is created on.

    • Replace vol_name with name of the volume for which you are setting the data-tiering policy.

    ::> volume show-space -vserver svm_name -volume vol_name

    If the command is successful, you'll see output similar to the following:

    Vserver : svm_name
    Volume  : vol_name

    Performance Metadata                      668KB         0%
    Total Used                              10.03GB        91%
    Total Physical Used                     10.03GB        91%

    The output of this command shows the amount of physical space that different types of data occupy on this volume. It also shows the percentage of the total volume's capacity that each type of data consumes. In this example, Snapshot Spill and Snapshot Reserve consume a combined 90 percent of the volume's capacity.

Snapshot Reserve shows the amount of disk space reserved for storing Snapshot copies. If the Snapshot copies storage exceeds the reserve space, it spills into the file system and this amount is shown under Snapshot Spill.

To increase the amount of available space, you can either increase the size of the volume, or you can delete snapshots that you are not using, as shown in the following procedures.

For FlexVol volume types (the default volume type for FSx for ONTAP volumes), you can also enable volume autosizing. When you enable autosizing, the volume size automatically increases when it reaches certain thresholds. You can also disable automatic snapshots. Both of these features are explained in the following sections.
