Modifying the Default Subclient for GlusterFS

You can configure only one GlusterFS volume for a subclient.

The default subclient does not back up the content you specify in user-defined subclients that are within the same instance.

To perform backups using the default subclient, you need to assign a new or existing storage policy to the subclient. The storage policy identifies a library that stores the backed-up data.


  1. From the CommCell Browser, expand Client Computers > pseudo-client > Big Data Apps > instance.
  2. Right-click the default subclient and then click Properties.

    The Subclient Properties dialog box appears.

  3. Specify the basic settings for the subclient:
    1. On the Data Access Nodes tab, select the data access nodes that you want to add to the subclient, and then click Add.
    2. On the Content tab, click Browse or Add Paths to include the content that you want to back up.


      • Subclient content paths can only be GlusterFS mount points. Ensure that only one GlusterFS volume is included per subclient.
      • The GlusterFS volume must be mounted as GlusterFS and not as NFS.
      • Nested GlusterFS mount points are not allowed.
  4. Click Advanced.

    The Advanced Subclient Properties dialog box appears.

  5. On the Performance tab, specify the number of data streams:
    1. In the Number of Data Readers box, enter the number of data streams.

      Tip: For optimal sharing of the backup load, the number of data readers must be equal or greater than the number of data access nodes.

    2. Select the Allow multiple data readers within a drive or mount point check box
    3. Click OK.
  6. On the Storage Device tab, select a storage policy from the Storage Policy list.
  7. To create a new storage policy, click Create Storage Policy, and then follow the instructions in the storage policy creation wizard.
  8. To perform LAN-free backup and restores, select a grid storage policy.

    For more information, see GridStor® (Alternate Data Paths) - Overview.

    By configuring keyless SSH between the GlusterFS cluster nodes and clients, you can also use the MediaAgent as GlusterFS clients.

  9. Click OK.
