Hi David,
thanks for your reply! I just fixed some problems in my cinder.conf and nova.conf's
and it is working now.
The solution for my problem was to make a new config section [ceph] and set it as the
default. My installation used an old LVM-backend I hat commented out in the config.
Thanks for your help!
Kind regards,
Kevin

What format is the image you are creating a volume from ? Are you able to reproduce the
problem with both qcow2 and raw formats ?

Help would be highly appreciated ;-)

Dear OpenStack-users,
I just installed my first multi-node OS-setup with Ceph as my storage backend.
After configuring cinder, nova and glance as described in the Ceph-HowTo
(http://docs.ceph.com/docs/master/rbd/rbd-openstack/), there remains one blocker for me:
When creating a new instance based on a bootable glance image (same ceph cluster), it
fails with:
Dashboard:
Block Device Mapping is Invalid.

Glance seems to work well. I was able to upload images.
Creating non-bootable disks seem to work, as soon as I try to make one bootable, it
fails.
This seems to be related to the known threads I found online but the mentioned fix was
merged long before Liberty so I am finaly stuck at this point.
How can I fix this problem?
Thanks.
Kind regards
Kevin
