Most volume managers can perform this movement online if the underlying hardware is hot-pluggable this allows engineers to upgrade or replace storage without system downtime.Ī hybrid volume is any volume that intentionally and opaquely makes use of two separate physical volumes. This may involve moving already-allocated LEs out of the PV. VGs can grow their storage pool by absorbing new PVs or shrink by retracting from PVs. This allows administrators conveniently to bring VGs online, to take them offline or to move them between host systems as a single administrative unit. PVs and LVs cannot be shared between or span different VGs (although some volume managers may allow moving them at will between VGs on the same host). A file system that can be resized online is recommended in that it allows the system to adjust its storage on-the-fly without interrupting applications. Changing the size of the LV does not necessarily change the size of a file system on it it merely changes the size of its containing space. Some volume managers allow the re-sizing of LVs in either direction while online. This allows LVs to grow without having to move already-allocated LEs. The concatenated LEs do not have to be contiguous. Striped LVs allocate each successive LE from a different PV depending on the size of the LE, this can improve performance on large sequential reads by bringing to bear the combined read-throughput of multiple PVs.Īdministrators can grow LVs (by concatenating more LEs) or shrink them (by returning LEs to the pool). Systems can use LVs as raw block devices just like disk partitions: creating mountable file systems on them, or using them as swap storage. The pooled LEs can then be concatenated together into virtual disk partitions called logical volumes or LVs. The system pools LEs into a volume group (VG). PVGs are usually laid out so that they reside on different disks or data buses for maximum redundancy. These PEs are drawn from a physical volume group (PVG), a set of same-sized PVs which act similarly to hard disks in a RAID1 array. With mirroring, multiple PEs map to each LE. Normally, PEs simply map one-to-one to logical extents (LEs). Some volume managers (such as that in HP-UX and Linux) have PEs of a uniform size others (such as that in Veritas) have variably-sized PEs that can be split and merged at will. Volume management treats each PV as being composed of a sequence of chunks called physical extents (PEs). They start with physical volumes (PVs), which can be either hard disks, hard disk partitions, or Logical Unit Numbers (LUNs) of an external storage device.

By the end of this tutorial, you’ll have a full understanding of how to use LVM and apply your own configurations. We’ll also show how to mount, extend, and remove our newly created logical volumes. LVM works the same on any Linux distribution, so you can use any of the commands below on your own system.įollow along with us as we use LVM to create partitions, physical volumes, a virtual group, logical volumes, and filesystems on a hard disk.
There’s no better way to learn about LVM than simply running through an example, which is exactly what we’ll do in the steps below. In this guide, you’ll learn how LVM works on Linux systems. As the name implies, it can sort raw storage into logical volumes, making it easy to configure and use. Logical Volume Manager (LVM) is used on Linux to manage hard drives and other storage devices.
