Re: [Rdo-list] OS Liberty + Ceph Hammer: Block Device Mapping is Invalid.

Can someone help me? Help would be highly appreciated ;-) Last message on OpenStack mailing list: 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. nova-compute.log (http://pastebin.com/bKfEijDu): > 2015-12-06 16:44:15.991 2333 ERROR nova.compute.manager [instance: 83677788-eafc-4d9c-9f38-3cad8030ecd3] Traceback (most recent call last): > 2015-12-06 16:44:15.991 2333 ERROR nova.compute.manager [instance: 83677788-eafc-4d9c-9f38-3cad8030ecd3] File "/usr/lib/python2.7/site-packages/nova/compute/manager.py", line 1738, in _prep_block_device > 2015-12-06 16:44:15.991 2333 ERROR nova.compute.manager [instance: 83677788-eafc-4d9c-9f38-3cad8030ecd3] wait_func=self._await_block_device_map_created) > 2015-12-06 16:44:15.991 2333 ERROR nova.compute.manager [instance: 83677788-eafc-4d9c-9f38-3cad8030ecd3] File "/usr/lib/python2.7/site-packages/nova/virt/block_device.py", line 476, in attach_block_devices > 2015-12-06 16:44:15.991 2333 ERROR nova.compute.manager [instance: 83677788-eafc-4d9c-9f38-3cad8030ecd3] map(_log_and_attach, block_device_mapping) > 2015-12-06 16:44:15.991 2333 ERROR nova.compute.manager [instance: 83677788-eafc-4d9c-9f38-3cad8030ecd3] File "/usr/lib/python2.7/site-packages/nova/virt/block_device.py", line 474, in _log_and_attach > 2015-12-06 16:44:15.991 2333 ERROR nova.compute.manager [instance: 83677788-eafc-4d9c-9f38-3cad8030ecd3] bdm.attach(*attach_args, **attach_kwargs) > 2015-12-06 16:44:15.991 2333 ERROR nova.compute.manager [instance: 83677788-eafc-4d9c-9f38-3cad8030ecd3] File "/usr/lib/python2.7/site-packages/nova/virt/block_device.py", line 385, in attach > 2015-12-06 16:44:15.991 2333 ERROR nova.compute.manager [instance: 83677788-eafc-4d9c-9f38-3cad8030ecd3] self._call_wait_func(context, wait_func, volume_api, vol['id']) > 2015-12-06 16:44:15.991 2333 ERROR nova.compute.manager [instance: 83677788-eafc-4d9c-9f38-3cad8030ecd3] File "/usr/lib/python2.7/site-packages/nova/virt/block_device.py", line 344, in _call_wait_func > 2015-12-06 16:44:15.991 2333 ERROR nova.compute.manager [instance: 83677788-eafc-4d9c-9f38-3cad8030ecd3] {'volume_id': volume_id, 'exc': exc}) > 2015-12-06 16:44:15.991 2333 ERROR nova.compute.manager [instance: 83677788-eafc-4d9c-9f38-3cad8030ecd3] File "/usr/lib/python2.7/site-packages/oslo_utils/excutils.py", line 195, in __exit__ > 2015-12-06 16:44:15.991 2333 ERROR nova.compute.manager [instance: 83677788-eafc-4d9c-9f38-3cad8030ecd3] six.reraise(self.type_, self.value, self.tb) > 2015-12-06 16:44:15.991 2333 ERROR nova.compute.manager [instance: 83677788-eafc-4d9c-9f38-3cad8030ecd3] File "/usr/lib/python2.7/site-packages/nova/virt/block_device.py", line 335, in _call_wait_func > 2015-12-06 16:44:15.991 2333 ERROR nova.compute.manager [instance: 83677788-eafc-4d9c-9f38-3cad8030ecd3] wait_func(context, volume_id) > 2015-12-06 16:44:15.991 2333 ERROR nova.compute.manager [instance: 83677788-eafc-4d9c-9f38-3cad8030ecd3] File "/usr/lib/python2.7/site-packages/nova/compute/manager.py", line 1426, in _await_block_device_map_created > 2015-12-06 16:44:15.991 2333 ERROR nova.compute.manager [instance: 83677788-eafc-4d9c-9f38-3cad8030ecd3] volume_status=volume_status) > 2015-12-06 16:44:15.991 2333 ERROR nova.compute.manager [instance: 83677788-eafc-4d9c-9f38-3cad8030ecd3] VolumeNotCreated: Volume eba9ed20-09b1-44fe-920e-de8b6044500d did not finish being created even after we waited 0 seconds or 1 attempts.

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.
