Julia Kreger 928a7dcc33 Ignored error state cache for new requests 
A possibility exists where inspector *can* fail upon inspection if
the database connectivity was lost on a prior action. This is because
the last database transport is potentially bad and fails upon load for
the transaction. The cache can then end up with an "error" state entry,
which upon retrying can fail becasue it is already in error state

Because there really are no guarentees regarding database failures,
the best thing to do is to not trust the prior cache state if it is
in error and to reset it to starting upon new introspection requests.
This prevents operators from *having* to perform process restarts to
force all loads to be from the database unless they manage to have a
multi-inspector cluster and get another inspector node to inspect in
the mean time.

Hardware introspection for OpenStack Bare Metal

Introduction

image

This is an auxiliary service for discovering hardware properties for a node managed by Ironic. Hardware introspection or hardware properties discovery is a process of getting hardware parameters required for scheduling from a bare metal node, given its power management credentials (e.g. IPMI address, user name and password).

Note

ironic-inspector was called ironic-discoverd before version 2.0.0.
