node-resource-manager is a node resource management component for ACK Edge clusters. This topic introduces the component, explains how to use it, and lists release notes. It reads your spec configuration, uses Logical Volume Manager (LVM) to create volume groups (VGs) and persistent volumes (PVs), and makes them available to persistent volume claims (PVCs), eliminating manual disk topology management.
How it works
node-resource-manager watches the node-level spec configuration and automatically:
-
Creates LVM volume groups from the local disks on each node
-
Provisions PVs and makes them available for PVCs
Prerequisites
Confirm the following:
-
Local disk topology is defined in the node
specconfiguration.
Use LVM to manage local storage
See Use LVM to manage local storage to define disk topology, create storage classes, and bind PVCs to workloads.
