If, when using a Ceph as a backend for Cinder and Glance, you create a volume from a Glance image, the request is actioned in one of two ways; (1) if Glance does not supply sufficient information to Cinder, a full copy is made of the Glance image or (2) Ceph uses it's copy-on-write capability to do a clone. If a full copy is done, the volume is marked as Bootable=True but if a clone is done it is not. This does not appear to break nova boot from volume at present but the status displayed by the cinder client is incorrect. Change-Id: I2959fc3dfaf0e073781583019797bcd44f7789d6 Fixes: bug 1185533
The Choose Your Own Adventure README for Cinder
You have come across a storage service for an open cloud computing service. It has identified itself as "Cinder." It was abstracted from the Nova project.
To monitor it from a distance: follow @openstack on twitter.
To tame it for use in your own cloud: read http://docs.openstack.org
To study its anatomy: read http://cinder.openstack.org
To dissect it in detail: visit http://github.com/openstack/cinder
To taunt it with its weaknesses: use http://bugs.launchpad.net/cinder
To watch it: http://jenkins.openstack.org
To hack at it: read HACKING
To cry over its pylint problems: http://jenkins.openstack.org/job/cinder-pylint/violations
