Overview

The procedures in this runbook require admin permissions to complete.

Error / Incident

A node has been offline (considered down) by a long period of time.

Debugging

This is quite a generic alert, so there's many options, but some things to try:

  • Try to ssh to the host
  • Try to ssh to the management port (see SRE/Dc-operations/Hardware_Troubleshooting_Runbook)
  • Ask on irc if someone is taking any action and forgot about it
  • Check SAL (or here) for host being rebooted/taken down
  • Check Netbox to make sure the host is not being decommed or network changes were not applied
  • Check puppet for recent changes that might have affected the node
