![]() ![]() ![]() You can use the lvdisplay for detailed information on the logical volumes currently in existence on your system. Seen below: ~]# lvcreate -L 500M -n lv_linear LVMvgTEST Here I am going to use a small portion of that volume group to create a linear logical volume titled, very creatively, lv_linear. That volume group was created by joining two unique 1G physical volumes. We created a 2G volume group called LVMvgTEST in our last article. They are generally used to combine one or more disks to create one usable storage unit. Linear logical volumes are the LVM default when it comes to logical volume creation. I will also walk you through a basic configuration of each. I will be discussing each of these volume types in further detail, walking you through examples of when and why you would want to use each one. You have a few different options at your disposal here, and they each have unique use cases that sysadmins can employ to best fit a given situation. If you are interested in the previous articles, you can review part 1 and part 2.Īs with all things, variation is the spice of life, and that's no different when it comes to technology-specifically, logical volumes. We will be continuing our LVM exploration by further splicing our newly created volume group LVMvgTEST into various logical volumes. If you have been following along in the series, you will have initialized your physical volumes and combined them into a volume group ( VG). These units are created from the volume group, which is made up of physical volumes ( PV). Logical Volumes ( LV) are the final storage unit in the standard LVM architecture.
