Adding a cache device to NAS Bridge

Every file system you create must be associated with a cache device. You should add cache devices to the NAS Bridge based on file systems that you plan to create.

Before you begin

You must have an available hard drive defined to the NAS Bridge virtual machine.


  1. Sign in to the NAS Bridge web interface.
  2. Click Configuration at the top of the web page.
  3. Click Cache Devices.
  4. Click Add.
  5. Type the name of the new cache device.
  6. Select the hard drive for this cache device from the Disk drop-down list.

    The drive name is shown as /dev/name, where name is the Linux-assigned name of the hard drive that was added when you performed the steps to add a hard drive to the virtual machine.

    Attention: If you are adding a cache device after upgrading the NAS Bridge, make sure to select the hard drive that you most recently added for cache device creation. Do not select a system drive, or you will lose access to your NAS Bridge file systems.
  7. Click Save.
    When the operation completes, the new cache device is displayed with a status of READY.

    The cache device is now available for use when adding file systems. Cache device usage will be displayed on the dashboard.

    2. Click Generate Package.
