• Troubleshooting Ironic-Python-Agent (IPA)
  • Gaining Access to IPA on a node
    • Access via ssh
      • ironic-python-agent-builder
    • Access via console
      • ironic-python-agent-builder: dynamic-login
      • ironic-python-agent-builder: devuser
    • How to pause the IPA for debugging
  • Set IPA to debug logging
  • Where can I find the IPA logs
  • Manually restart IPA
  • Cleaning halted with ProtectedDeviceError
    • What filesystems are looked for
    • I’m okay with deleting, how do I tell IPA to clean the disk(s)?
      • Via Ironic
      • Via a node’s kernel_append_params setting
      • Via Ironic’s Boot time PXE parameters (Globally)
      • Via Ramdisk configuration
  • Cleaning takes hours because the firmware froze the disks
