I Integrated Ceph + OpenStack with following document. https://ceph.com/docs/master/rbd/rbd-openstack/
I could put image to glance on ceph cluster. but I can not create any volume to cinder. error messages are the same on this URL. http://comments.gmane.org/gmane.comp.file-systems.ceph.user/7641 --- 2014-04-02 17:31:57.799 22321 ERROR cinder.volume.drivers.rbd [req-b18d0e8d-c818-4fb4-9dd8-dbdd938f919b None None] error connecting to ceph cluster 2014-04-02 17:31:57.799 22321 TRACE cinder.volume.drivers.rbd Traceback (most recent call last): 2014-04-02 17:31:57.799 22321 TRACE cinder.volume.drivers.rbd File "/usr/lib/python2.7/dist-packages/cinder/volume/drivers/rbd.py", line 262, in check_for_setup_error 2014-04-02 17:31:57.799 22321 TRACE cinder.volume.drivers.rbd with RADOSClient(self): 2014-04-02 17:31:57.799 22321 TRACE cinder.volume.drivers.rbd File "/usr/lib/python2.7/dist-packages/cinder/volume/drivers/rbd.py", line 234, in __init__ 2014-04-02 17:31:57.799 22321 TRACE cinder.volume.drivers.rbd self.cluster, self.ioctx = driver._connect_to_rados(pool) 2014-04-02 17:31:57.799 22321 TRACE cinder.volume.drivers.rbd File "/usr/lib/python2.7/dist-packages/cinder/volume/drivers/rbd.py", line 282, in _connect_to_rados 2014-04-02 17:31:57.799 22321 TRACE cinder.volume.drivers.rbd client.connect() 2014-04-02 17:31:57.799 22321 TRACE cinder.volume.drivers.rbd File "/usr/lib/python2.7/dist-packages/rados.py", line 408, in connect 2014-04-02 17:31:57.799 22321 TRACE cinder.volume.drivers.rbd raise make_ex(ret, "error calling connect") 2014-04-02 17:31:57.799 22321 TRACE cinder.volume.drivers.rbd ObjectNotFound: error calling connect 2014-04-02 17:31:57.799 22321 TRACE cinder.volume.drivers.rbd 2014-04-02 17:31:57.800 22321 ERROR cinder.volume.manager [req-b18d0e8d-c818-4fb4-9dd8-dbdd938f919b None None] Error encountered during initialization of driver: RBDDriver 2014-04-02 17:31:57.801 22321 ERROR cinder.volume.manager [req-b18d0e8d-c818-4fb4-9dd8-dbdd938f919b None None] Bad or unexpected response from the storage volume backend API: error connecting to ceph cluster 2014-04-02 17:31:57.801 22321 TRACE cinder.volume.manager Traceback (most recent call last): 2014-04-02 17:31:57.801 22321 TRACE cinder.volume.manager File "/usr/lib/python2.7/dist-packages/cinder/volume/manager.py", line 190, in init_host 2014-04-02 17:31:57.801 22321 TRACE cinder.volume.manager self.driver.check_for_setup_error() 2014-04-02 17:31:57.801 22321 TRACE cinder.volume.manager File "/usr/lib/python2.7/dist-packages/cinder/volume/drivers/rbd.py", line 267, in check_for_setup_error 2014-04-02 17:31:57.801 22321 TRACE cinder.volume.manager raise exception.VolumeBackendAPIException(data=msg) 2014-04-02 17:31:57.801 22321 TRACE cinder.volume.manager VolumeBackendAPIException: Bad or unexpected response from the storage volume backend API: error connecting to ceph cluster so I added these lines to /etc/ceph/ceph.conf [client.cinder] key = <key_id> but I could not create any volumes to cinder. Does anyone have an idea ? Thanks from cloudy Tokyo. -- Tomokazu HIRAI (@jedipunkz)
