This topic describes how to expand the storage for an instance of Data Science Workshop (DSW) 1.0. By default, the system provides 5 GB of storage for each DSW instance. If the storage space is exhausted or the file size is larger than 5 GB, you must expand the storage of the instance.

Step 1: Create a NAS file system

For more information about how to create a NAS file system, see Manage file systems. DSW 1.0 supports only Capacity and Performance NAS file systems. Therefore, you must choose the General Purpose instance family when you purchase NAS file systems. The NAS file system that you want to create and the DSW instance to which you want to mount the NAS file system must be deployed in the same region. For example, if you want to use a DSW instance in the China (Beijing) region, you must deploy the NAS file system in the China (Beijing) region.

Step 2: Mount a NAS file system

DSW 1.0 allows you to mount a NAS file system to a DSW instance by using one of the following methods:
  • Mount a NAS file system to a DSW instance when you create the DSW instance.

    When you set the parameters of the DSW instance, select Storage Settings, and enter the ID of the NAS file system in the NAS File System ID field. For more information, see Manage instances.

  • If you want to mount a NAS file system to a created DSW instance, you must modify the configurations of the instance.

    You must stop the instance before you modify its configurations. When you modify the DSW instance, select Storage Settings, and enter the ID of the file system in the NAS File System ID field. For more information, see Manage instances.

Step 3: Use the mounted NAS file system

  1. On the Notebook Models page, click Launch DSW in the Actions column.
  2. On the Data Science Workshop page, choose File > New > Terminal to create a Terminal file.Create a Terminal file
  3. Run the df command to view the path of the mounted NAS file system.

    Callout Description
    The path of the mounted NAS file system.
    The path of the default NAS file system (5 GB).
  4. Optional:If you want to use DSW 1.0 to upload files to the mounted NAS file system, you can create a symbolic link pointing to /nas in the /home/admin/jupyter directory.
    Create a symbolic link
    sh-4.2$ cd /home/admin/jupyter/
    sh-4.2$ ls
    dddd.txt  graph.fnn.ipynb  nihao.ipynb       Sequential.ipynb
    Demo      nihao2.ipynb     number.fnn.ipynb  image.png
    sh-4.2$ ln -s /nas/ mynas
    sh-4.2$ ls
    dddd.txt  graph.fnn.ipynb  nihao2.ipynb  number.fnn.ipynb  image.png
