#To create the logical volume, we will use:
lvcreate -L 3G -n lvstuff vgpool
The -L command designates the size of the logical volume, in this case 3 GB, and the -n command names the volume. Vgpool is referenced so that the lvcreate command knows what volume to get the space from.
#Format and Mount the Logical Volume One final step is to format the new logical volume with a file system. If you want help choosing a Linux file system, read our how to that can help you choose the best file system for your needs.
mkfs -t ext3 /dev/vgpool/lvstuff
#Create a mount point and then mount the volume somewhere you can use it.
mkdir /mnt/stuff
mount -t ext3 /dev/vgpool/lvstuff /mnt/stuff
