This is unreleased documentation for SUSE® Storage 1.9.0 (Dev).

Configurable CPU Cores

Longhorn now supports configurable CPU cores for the V2 Data Engine, offering both global and node-specific configuration options.

Global Configuration

Update the v2-data-engine-cpu-mask setting using a hexadecimal encoded string.

Examples:

  • Use 0x01 to allocate 1 core.

  • Use 0x03 to allocate 2 cores.

  • Use 0x07 to allocate 3 cores.

Node-Specific Configuration

Update the spec.dataEngineSpec.v2.cpuMask field of the instance manager with a hexadecimal encoded string. By default, this value is empty, and the V2 Data Engine uses the global setting v2-data-engine-cpu-mask. When a node-specific setting is configured, the V2 Data Engine prioritizes this value over the global setting for that specific node.
