Volumes Volumes Volumes are created, viewed, edited, and deleted from the Storage > Volumes screen of the Administration Tool. The default volume organizes the SnapServer's storage capacity into a single volume with a single file system. If you need separate file systems on the same server, you can delete the default volume and create two or more smaller volumes in its place. Consider the following facts and guidelines when planning your new volume configuration. Volumes and the Snapshot Pool The default disk and RAID capacity is divided between the file system (80 percent) and the space left available for future snapshot use (20 percent). You may need to adjust this figure depending on your snapshot strategy or expand the volume to all available space if you plan never to use snapshots. Keep in mind that you can increase or decrease snapshot pool size at any time, but volume space can only be increased. For more information, see "Estimating Snapshot Pool Requirements" on page 113. Note GuardianOS snapshots should not be used on volumes that contain iSCSI disks. If a volume will contain one or more iSCSI disks, decrease the Snapshot pool size to zero. For information about creating snapshots of iSCSI disks, see "Configuring VSS/VDS for iSCSI Disks" on page 93. Deleting Volumes Deleting volumes may move or disable certain third party applications that are installed on the user volume space. The NetVault for GuardianOS Database Directory (NVDB), containing files that keep track of the data you back up; the antivirus software; and Snap EDR reside on the default volume. If you delete the default volume, these components will also be deleted unless there is available space on additional volumes (e.g., on expansion arrays). To retain NVDB information, you must back up the NVDB directory (see page 120) before you delete the volume, create your new storage configuration, and then restore the directory. After creating your new storage configuration, you can reinstall the antivirus software by navigating to the Snap Extensions screen and selecting CA Antivirus. On the next screen, check the Enable check box and click OK. The SnapServer reinstalls the antivirus software (using default settings) on the volume with the most available space. However, the installation process does not preserve custom antivirus configuration settings, so make a note of any such settings before deleting 56 SnapServer Administrator Guide
