Expanding a File System

Expanding a File System

This section describes how a user with super administrator permissions expands storage space on DeviceManager and allocates the expanded capacity to an application server.



  1. Check that the storage pool of the file system to be expanded has sufficient free space to meet the expansion need.
    1. In the navigation tree on the right, click Provisioning.
      The Provisioning page is displayed.
    2. Click Storage Pool. Check the total capacity, allocated capacity, and free capacity of the storage pool that houses the file system to be expanded.

      • If the free capacity is sufficient, go to 5.
      • If the free capacity is insufficient, record the disk domain of the storage pool and go to 2.

  2. Return to the Provisioning page and click Disk Domain. Check the total capacity, allocated capacity, and free capacity of the disk domain.

    • If the free capacity meets expansion requirements, go to 4.
    • If the free capacity does not meet expansion requirements, go to 3.

  3. Expand a disk domain.
    1. In the Disk Domain area, select a disk domain that you want to expand and click Expand.
    2. On the page for expanding a disk domain, select the type and number of disks that you want to expand, and ensure that the disk domain has enough free space to meet file system expansion requirements.

      • All available disks

        All available disks of the storage system are included.

      • Specifying a disk type

        Type and number of disks must be specified.

      • Manually selecting disks

        Optional disks must be manually selected and added.

      The capacity of a disk to be added must not be smaller than the minimum capacity of existing disks in a disk domain. For example, if the disk domain contains both 600 GB and 900 GB disks, then the capacity of a disk to be added must not be smaller than 600 GB.

    3. Click OK.

      The Success dialog box is displayed.

    4. Click OK.
  4. Expand a storage pool.
    1. In the Storage Pool area, select the storage pool that you want to expand and click Modify Capacity.
    2. In the page of modifying capacity, choose Expand capacity and in the Added Capacity area, enter the value of the capacity that you want to expand and select the unit.
    3. Click OK. The Warning dialog box is displayed. Select I have read and understood the consequences associated with performing this operation and click OK.

      The Execution Result dialog box is displayed.

    4. Click Close.
  5. Expand a file system.
    1. Under File Storage Service on the Provisioning page, click File System.
      The File System page is displayed.
    2. Select a file system that you want to expand, click More, and select Modify Capacity.
      Go to the Modify File System Capacity dialog box.
    3. In Capacity of the File System Capacity area, enter the value of the capacity that you want to expand and select the unit.
    4. Click OK. In the Execution Result dialog box that is displayed, click Close.
  6. Verify and use the expanded storage space.

    On the File System page, click the newly expanded file system and view its Total Capacity.

    If the capacity is expanded to the correct value, the expansion is successful. If the expansion is unsuccessful, troubleshoot the fault based on alarm information.
