Rename NOSTATE to AVAILABLE
This patch adds the new provisioning state AVAILABLE, and bumps the API
microversion to 1.1. This version exposes the renaming of the previous
provision_state="None" to provision_state="available" for nodes which
are available for use.
A database migration is added which updates all DB records'
provision_state from NOSTATE to AVAILABLE.
Since database migrations and code changes may be rolled out at
different times, the conductor can deploy to a node in either
NOSTATE or AVAILABLE states.
OperatorImpact:
This change should be rolled out to production services, and the
conductor service should be restarted, *before* the database
migration is applied. Ironic will then begin "translating" existing
node states to the new AVAILABLE state automatically when it touches
them. If the DB migration is run much later, it may not actually
update any records (and that is OK).
DocImpact:
This change updates the Node provision_state value which represents
a node that is available for provisioning. It is changed from
"None" to "available", but this change is only realized when the
X-OpenStack-Ironic-API-Version header is >= 1.1
*** NOTE ***
Nova interprets the provision_state of Nodes to determine which should
be exposed to the scheduler and counted as available resources. Up to
the Juno release, Nova looked for the "NOSTATE" state to indicate this,
represented as provision_state=None.
After commit Idbd36b230cf997bed7a86c3f56cf9c70995028b2 landed in Nova,
both the old "None" and new "available" states are interpreted in this
way. As such, Nova may continue to use Juno Ironic, which did not
support microversions, or may begin using the 1.1 version.
