Open 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.

Steps

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

    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: cifs
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

    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.

Results

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