Opening the export policy of the SVM root volume

The default export policy of the SVM root volume must include a rule to allow all clients open access through SMB. Without such a rule, all SMB clients are denied access to the SVM and its volumes.

About this task

When a new SVM is created, a default export policy (called default) is created automatically for the root volume of the SVM. You must create one or more rules for the default export policy before clients can access data on the SVM.

You should verify that all SMB access is open in the default export policy, and later restrict access to individual volumes by creating custom export policies for individual volumes or qtrees.

  1. If you are using an existing SVM, check the default root volume export policy: vserver export-policy rule show

    Example

    The command output should be similar to the following:

    cluster::> vserver export-policy rule show -vserver vs1.example.com -policyname default -instance

                                        Vserver: vs1.example.com
                                    Policy Name: default
                                     Rule Index: 1
                                Access Protocol: <span className="ph">cifs</span>
    Client Match Hostname, IP Address, Netgroup, or Domain: 0.0.0.0/0
                                 RO Access Rule: any
                                 RW Access Rule: any
    User ID To Which Anonymous Users Are Mapped: 65534
                       Superuser Security Types: any
                   Honor SetUID Bits in SETATTR: true
                      Allow Creation of Devices: true


    Result

    If such a rule exists that allows open access, this task is complete. If not, proceed to the next step.

  2. Create an export rule for the SVM root volume: vserver export-policy rule create -vserver vserver_name -policyname default -ruleindex 1 -protocol cifs -clientmatch 0.0.0.0/0 -rorule any -rwrule any -superuser any
  3. Verify rule creation by using the vserver export-policy rule show command.

Result

Any SMB client can now access any volume or qtree created on the SVM.
