Description Stephen Gordon 2015-09-08 14:48:34 UTC 
Cloned from launchpad blueprint https://blueprints.launchpad.net/nova/+spec/mark-host-down.

Description:

New API call is needed to change the state of compute service "down"
immediately. This allows usage of evacuate API without a delay. Also as
external system will make sure host is down and no VMs left running, there
will be no possibility to break shared storage or use same IPs again.

Hi Fabio,

How would you like to track the need to also update the agent(s) to take advantage of this API if it's available?

Thanks,

Steve

As soon as the API is available in RDO we can clone the bz for fence-agents but we need to keep in mind that fence-agents is in RHEL Base OS and follows a different schedule. so we need to be a bit smart in landing the code to avoid sync issues.
