Steps

Using the Cockpit web console, follow these steps to create a volume group.

In the Storage page, find the three-line menu icon in the Devices table and select Create LVM2 volume group.
The Create LVM2 volume group dialog appears.

In the Create LVM2 Volume Group dialog, specify the following properties and then click Create.

Name

Enter a volume group name.

For example, vg1, vg2, or provide a name that identifies the purpose of the volume group. For example, if you're creating the volume group to configure "thin" logical volumes, you might want to use a volume name such as Thin Volume Group.

The LVM group name is limited to 128 characters.

Disks

In the Disks drop down list box, select the drives you want to include in the volume group.

Note:

A message "No disks available" appears when the host system doesn't have an unallocated storage device (such as a partition with no file system) to add.

The name of the new volume group appears in the Devices table on the Storage page. You can click the New volume group to create logical volumes. For details, see Create a Logical Volume.
