Arne Wiebalck 6e0d08c892 Software RAID: RAID the ESPs 
For software RAID in UEFI mode, we create ESPs on all holder disks
and copy the bootloader there. Since there is no mechanism to keep
the ESPs in sync, e.g. on kernel upgrades or when kernel parameters
are updated, the ESPs will get out of sync eventually. This may lead
to a situation where a node boots with outdated parameters or does
not have any of the installed kernels in the boot menu anymore.
This change proposes to RAID the ESPs. While the UEFI firmware will
find an ESP partition (one leg of the mirror), the node will see
an md device and all subsequent updates will go to all member disks.

Also, remove the source ESP after copying in order to avoid mount
confusion (same UUID!).

Ironic Python Agent

Team and repository tags

Overview

An agent for controlling and deploying Ironic controlled baremetal nodes.

The ironic-python-agent works with the agent driver in Ironic to provision the node. Starting with ironic-python-agent running on a ramdisk on the unprovisioned node, Ironic makes API calls to ironic-python-agent to provision the machine. This allows for greater control and flexibility of the entire deployment process.

The ironic-python-agent may also be used with the original Ironic pxe drivers as of the Kilo OpenStack release.

Building the IPA deployment ramdisk

For more information see the Image Builder section of the Ironic Python Agent developer guide.

Using IPA with devstack

This is covered in the Deploying Ironic with DevStack section of the Ironic dev-quickstart guide.
