Steps

Using the Cockpit web console, follow these steps to add a new drive to an established volume group.

1. In the Storage page, find the Devices table and select the volume group in which you want to add a new drive.

   The LVM2 group [name] page appears.

2. In the LVM2 group [name] page, navigate to the Physical volumes table.
3. In the Physical volumes table, click the plus [+] sign icon.

   The Add Disks dialog appears.

4. In the Add Disks dialog, perform the following:
   1. In the Disks drop-down list box, select the check boxes for the disk that you want to add.

      Note:

      If LVM doesn't detect an unformatted drive attached to the host system, a message "No disks are available" appears.
   2. Click Add.

      LVM adds the selected drives to the volume group and the space on the new drive is ready to be allocated to a logical volume within that volume. For example, in the that volume group, you can choose to increase the size of an existing logical volume (see, Resize Logical Volumes ) or allocate the space to a new logical volume (see, Create a Logical Volume).
