In the output of vgdisplay, the Total PE field displays the number of physical extents in the volume group.

The size of each physical extent is displayed in the PE Size field (the default is 4 Mbyte), so the total capacity of this volume group is 2167 x 4 Mbyte = 8668 Mbyte.

The Alloc PE field shows the number of physical extents allocated to logical volumes. At this point, the Alloc PE field is zero because we have not assigned any of this volume group’s capacity to logical volumes.

I.8 Creating a Logical Volume

To create a logical volume within the volume group, use the lvcreate command with the -Loption to specify the size of the logical volume in megabytes. The logical volume size should be a multiple of the physical extent size. In this example, a logical volume of 4092 Mbyte is created:

# lvcreate -L 4092 /dev/vg02
