Adding a virtual volume

A file system can be divided into discrete areas of storage that are called virtual volumes. You can add a virtual volume in the NAS Manager.

1. Navigate to Home > Storage Management > Virtual Volumes & Quotas
2. Click add to display the Add Virtual Volume page.
   
   

   

   
   

   The following table describes the fields on this page:

   Field/Item	Description
   EVS/File System	The EVS and the file system to which to add this virtual volume. If the volume will be added to a different EVS/file system, click change and select an EVS/file system.
   Virtual Volume Name	The name of the virtual volume.
   Create a CIFS Share or NFS Export with the same name as the virtual volume	If a share or export with the same name as the virtual volume does not exist, selecting this check box ensures its creation. This is only intended for convenience in accessing the virtual volume through CIFS or NFS.
   Allow exports to overlap	As overlapping exports can potentially expose security loopholes, the condition can be tested for and, if found, the export creation can be denied.
   Path	Directory in the file system that will be the root of the virtual volume; for example, /company/sales. All subdirectories of this path will be a part of this volume. The path to the directory at the root of the virtual volume must be specified, or selected by browsing the file system. If the directory does not yet exist, then leaving the box checked will ensure it is created. It should be noted that if the system is left to create the directory in this way, the owner will be designated 'root', and the default quotas for this virtual volume will be named anonymously.
   Email Contacts	Email contacts to receive information about virtual volume usage.

3. In the Virtual Volume Name field, enter the name. Note the the following:
   • The name can be up 128 characters.
   • Do not use the characters ?*=+[];:/,<>\| in the name.
   • The name A$ is reserved for the Windows Event Viewer, and cannot be used.
4. If a CIFS share of the same name as this virtual volume is required, fill the Create a CIFS Share with the same name as the Virtual Volume check box. Selecting this check box ensures its creation.

5. if an NFS export with the same name as the virtual volume is required, fill in the Create a NFS Export with the same name as the Virtual Volume check box.
6. If there is a possibility that this new NFS export will overlap an existing export, fill in the Allow exports to overlap check box.
7. Enter the path to the directory at the root of the virtual volume or click Browse and navigate to the file system path.
8. If the directory does not yet exist, fill in the Create path if it does not exist check box to ensure that it is created.
9. Enter each email address in the Email Contacts box, and click add to append it to the list. Email lists are limited to a maximum of 512 characters.
   • To configure email notification of threshold alerts, designate explicit email recipients (for example, admin@company.com) to receive email notification any time a defined threshold has been reached.
   • To send email to all affected user accounts when their user quota has been reached, add an email address beginning with * to the Email Contacts list (for example, *@example.com).
   Note: If no email contacts are specified for the virtual volume, the server generates events for quota warnings. To generate events in addition to email alerts, go to the server’s command line interface and issue the command quota-event–-on.
10. Click OK.
