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 NFS. Without such a rule, all NFS 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 access is open to all NFS clients 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

    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:  nfs
    Client Match Hostname, IP Address, Netgroup, or Domain:
                                 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 nfs -clientmatch -rorule any ‑rwrule any -superuser any

    If the SVM will only contain volumes secured by Kerberos, you can set the export rule options -rorule, -rwrule, and -superuser for the root volume to krb5 or krb5i. For example:

    -rorule krb5i -rwrule krb5i -superuser krb5i

  3. Verify rule creation by using the vserver export-policy rule show command.


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