Managing Exports

NFS exports are directories in the NFS file system that are exported by the NFS server for NFS clients to mount like local directories.

By default, the NFS file system is undivided, with one default export at path '/'. Divide your NFS file system into a useful set of exported directories that reflects your organization's structure.  

Tip

Use export policies to control which host IPs can access different exports.

Managing Exports from the VAST Web UI

Creating Exports

  1. From the menu (click menu_button.png), select Configuration and then select the Exports tab.

  2. Click add_button.png.

  3. Complete the fields:

    Field

    Description

    Path

    The path to the directory to export. 

    Alias (optional)

    A shortcut that NFS clients can specify as the mount point instead of the full path.

    Policy

    The export policy that controls client access to the export. 

    Cluster

    The cluster on which to create the export. 

    POSIX ACL

    Enable this setting for full support of POSIX Access Control Lists (ACL). We recommend to leave this setting disabled if you are not using extended ACLs. By default, VAST Cluster supports the traditional POSIX file system object permission mode bits, (minimal ACL mode) in which each file has three ACL entries defining the permissions for the owner, owning group, and others, respectively. To learn more about POSIX ACL, see https://linux.die.net/man/5/acl.

    Note

    Thesetfacl Linux command is blocked if Posix ACL is not enabled.

    Create Directory

    Creates the directory to be exported. By default, no directory is created.  Enable this setting unless the directory was already created some other way, such as from the client side, inside a mounted parent directory.

  4. Click Create.  

    The export is created. 

Modifying Exports

  1. Click the export's row in the Exports page (menu_button.png > Configuration > Exports).  

  2. Make your changes (see Creating Exports)

  3. Click Update to save your changes.

Deleting Exports

  1. At the far right column of the export's row in the Exports page (menu_button.png > Configuration > Exports), hover until the delete_button.png button appears and click it. 

  2. Click Yes to confirm the deletion.
