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, 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 - for dynamically allocated local storage for Kubernetes workloads.
  • Raw Volumes - for allocating unformatted storage (e.g. to be used with CSIs).
  • Existing Volumes - for mounting pre-existing partitions or disks.
For information on allocating swap space, see Swap Management. Configuration documents related to volume management are located in the block group, see common configuration for common fields in volume configuration documents.
