You can use the console to create and start new volumes featuring a single global namespace. A volume is a logical collection of bricks where each brick is an export directory on a server in the trusted storage pool. Most of the management operations of Red Hat Storage Console happen on the volume.
The volume is the designated unit of administration in Red Hat Storage, so managing them is a large part of the administrator's duties.
The console also enables you to monitor the volumes in your cluster from the Volumes tab. To display the volumes, click the Volumes node from the left tree of the console window. The list of the volumes is displayed in the right pane of the console window. It also displays Tasks and Alerts of all the volumes.
This chapter describes how you can manage your volumes stored on the storage server machines.

5.1. Creating a Volume

You can create new volumes in your storage environment. When creating a new volume, you must specify the bricks that comprise the volume and specify whether the volume is to be distributed, replicated, or striped.
To create a volume, perform the following steps.
  1. Click the Volumes tab. The Volumes tab displays a list of all volumes in the system.
  2. Click the Create Volume button. The Create Volume dialog box displays.

  3. Select the cluster from the Volume Cluster drop-down list.
  4. In the Name field, enter the name of the volume.
  5. Select the type of the volume from the Type drop-down list. You can choose the volume type as Distribute, Replicate, or Stripe.
  6. If you wish to add bricks to your volume, click Add Bricks.
    For more information on adding bricks to your volume, refer to Section 5.6.1, “Adding Bricks”
  7. Select the Access Protocol for the new volume by selecting GlusterFS,or NFS, or both checkboxes.
  8. In the Allow Access From field, specify the volume access control as a comma-separated list of IP addresses or hostnames.
    You can use wildcards to specify ranges of addresses such as an asterisk (*) which specifies all IP addresses or hostnames. You need to use IP-based authentication for Gluster Filesystem and NFS exports.
  9. Click OK to create the volume. The new volume is added and displays on the Volume tab.
