# Overview

> Guide on managing disks

This guide provides an overview of the disk management features in Talos Linux.

## Disk and volume discovery

See [Disk Layout](https://docs.siderolabs.com/talos/v1.15/configure-your-talos-cluster/storage-and-disk-management/disk-management/layout.md) for details on the disk layout and how to observe discovered disks and volumes.

## Volume management

Talos Linux implements disk management through the concept of volumes.
A volume represents a provisioned, located, mounted, or unmounted entity, such as a disk, partition, or a directory/overlay mount.

Talos Linux has [built-in (system) volumes](https://docs.siderolabs.com/talos/v1.15/configure-your-talos-cluster/storage-and-disk-management/disk-management/system.md), which can be partially configured by the user, and user-defined volumes, which are fully configurable by the user.
User volumes come in several flavors:

* [User Volumes](https://docs.siderolabs.com/talos/v1.15/configure-your-talos-cluster/storage-and-disk-management/disk-management/user.md) - for dynamically allocated local storage for Kubernetes workloads.
* [Raw Volumes](https://docs.siderolabs.com/talos/v1.15/configure-your-talos-cluster/storage-and-disk-management/disk-management/raw.md) - for allocating unformatted storage (e.g. to be used with CSIs).
* [Existing Volumes](https://docs.siderolabs.com/talos/v1.15/configure-your-talos-cluster/storage-and-disk-management/disk-management/existing.md) - for mounting pre-existing partitions or disks.

For information on provisioning LVM volume groups and logical volumes, see [LVM](https://docs.siderolabs.com/talos/v1.15/configure-your-talos-cluster/storage-and-disk-management/lvm.md).
For information on allocating swap space, see [Swap Management](https://docs.siderolabs.com/talos/v1.15/configure-your-talos-cluster/storage-and-disk-management/swap.md).

Configuration documents related to volume management are located in the [`block` group](../../../reference/configuration/block), see [common configuration](https://docs.siderolabs.com/talos/v1.15/configure-your-talos-cluster/storage-and-disk-management/disk-management/common.md) for common fields
in volume configuration documents.
