rm: cannot remove ‘alloc/ddcf5a78-5497-f4a4-a101-221fc4e0180b/fabio/alloc’: Device or resource busy

Job Anti-Affinity in Action

Overview

This guide will walk you through creating and executing a job that will demonstrate Nomad's job anti-affinity rules and, in clusters with memory limited Nomad clients, filtering based resource exhaustion.

Sample Environment

• One Nomad Server Node
• Three Nomad Client Nodes
  • 768 MB RAM total (providing 761 MB RAM in nomad node-status -self)
