ECS 3.6.1 Administration Guide

Add an NFS export using the ECS Portal

You can use the ECS Portal to create an NFS export and set the options that control access to the export.

1. In the ECS Portal, select File > Exports > New Export.
   The New File Export page is displayed.
2. On the New File Export page, in the Namespace field, select the namespace that owns the bucket that you want to export.
3. In the Bucket field, select the bucket.
4. In the Export Path field, specify the path.
   ECS automatically generates the export path that is based on the namespace and bucket. You only have to enter a name if you are exporting a directory that exists within the bucket. So if you enter /namespace1/bucket1/dir1, for example, you should ensure that dir1 exists. If it does not, mounting the export fails.
5. Set the Show Bucket Quota option to No or Yes depending on how you want the export size to be reported.

   Option	Description
   No	The export size is reported as the storage pool size.
   Yes	The export size is reported as the hard quota on the bucket, if set.

6. To add the hosts that you want to be able to access the export, complete the following steps:
   1. In the Export Host Options area, click Add.
      The Add Export Host dialog is displayed.
   2. In the Add Export Host dialog, specify one or more hosts that you want to be able to access the export and configure the access options.
      You must choose an Authentication option. This is normally Sys unless you are intending to configure Kerberos. Default values for Permissions (ro) and Write Transfer Policy (async) are already set in the Add Export Host dialog and are passed to the NFS server. The remaining options are the same as the NFS server defaults and so are only passed by ECS if you change them.
      The following table describes the parameters that you can specify when you add a host:

      Setting	Description
      Export Host	Sets the IP address of the host or hosts that can access the export. Use a comma-separated list to specify more than one host.
      Permissions	Enables access to the export to be set as Read/Write or Read only. This is the same as setting rw or ro in /etc/exports.
      Write Transfer Policy	Sets the write transfer policy as synchronous or asynchronous. The default is asynchronous. This parameter is the same as setting sync or async for an export in /etc/exports.
      Authentication	Sets the authentication types that are supported by the export.
      Mounting Directories Inside Export	Specifies whether subdirectories of the export path are allowed as mount points. This parameter is the same as the alldir setting in /etc/exports. With the alldir option, if you exported /namespace1/bucket1, for example, you can also mount subdirectories, such as/namespace1/bucket1/dir1, provided the directory exists.
      AnonUser	An object user name (must have an entry in user/group mapping) to which all unknown (not mapped using the user/group mapping) user IDs will be mapped when accessing the export. NOTE For performance reasons, user mapping must be predefined and can be selected here.
      AnonGroup	An object group name (must have an entry in user/group mapping) to which all unknown (not mapped using the user/group mapping) group IDs will be mapped when accessing the export. NOTE For performance reasons, group mapping must be predefined and can be selected here.
      RootSquash	An object user name to which the root user ID (0) will be mapped when accessing the export.

      NOTE The AnonUser/AnonGroup is the object user/group name that is used to map any incoming user id. This overrides user mapping provided at the Namespace level.
   3. Click Add to finish defining the host options.
7. If you want to add more hosts that can access the export, but with different options, repeat the previous step.
8. Click Save to save the NFS export definition.
