In case /var/lib/nova/instances resides on NFS we have seen migrations failing with 'Failed to get "write" lock - Is another process using the image' errors. This has been tracked down to grace/lease timeouts not having expired before attempting the migration/evacuate, so in this cases it might be desirable to delay the nova evacuate call to give the storage time to release the locks.

Pacemaker High Availability resource agents for OpenStack
This repository contains a collection of Pacemaker resource agents (RAs) which can be used to provide highly available OpenStack services managed within Pacemaker clusters.
Usage
Please see the OpenStack High Availability Guide for usage instructions. It is a bit out of date, but most of the information is still accurate; hopefully we can update it soon.
Development
Bugs can be viewed and reported via <https://launchpad.net/openstack-resource-agents>.
Suggestions for improvements are very welcome; changes can be submitted for review via the normal OpenStack development process.
History
Martin Loschwitz started this repository in 2012, hosted at <https://github.com/madkiss/openstack-resource-agents>, and together with Sébastien Han and Emilien Macchi contributed the majority of resource agents.
Martin eventually stepped down from maintainership, and in October 2015 the project was moved to StackForge.
