Hi Cephers, I am trying to configure ceph rbd as backend for cinder and glance by following the steps mentioned in:
http://ceph.com/docs/master/rbd/rbd-openstack/ Before I start all openstack services are running normally and ceph cluster health shows "HEALTH_OK" But once I am done with all steps and restart openstack services, cinder-volume fails to start and throws an error. 2014-02-16 00:01:42.582 TRACE cinder.volume.drivers.rbd Traceback (most recent call last): 2014-02-16 00:01:42.582 TRACE cinder.volume.drivers.rbd File "/opt/stack/cinder/cinder/volume/drivers/rbd.py", line 262, in check_for_setup_error 2014-02-16 00:01:42.582 TRACE cinder.volume.drivers.rbd with RADOSClient(self): 2014-02-16 00:01:42.582 TRACE cinder.volume.drivers.rbd File "/opt/stack/cinder/cinder/volume/drivers/rbd.py", line 234, in __init__ 2014-02-16 00:01:42.582 TRACE cinder.volume.drivers.rbd self.cluster, self.ioctx = driver._connect_to_rados(pool) 2014-02-16 00:01:42.582 TRACE cinder.volume.drivers.rbd File "/opt/stack/cinder/cinder/volume/drivers/rbd.py", line 282, in _connect_to_rados 2014-02-16 00:01:42.582 TRACE cinder.volume.drivers.rbd client.connect() 2014-02-16 00:01:42.582 TRACE cinder.volume.drivers.rbd File "/usr/lib/python2.7/dist-packages/rados.py", line 185, in connect 2014-02-16 00:01:42.582 TRACE cinder.volume.drivers.rbd raise make_ex(ret, "error calling connect") 2014-02-16 00:01:42.582 TRACE cinder.volume.drivers.rbd Error: error calling connect: error code 95 2014-02-16 00:01:42.582 TRACE cinder.volume.drivers.rbd 2014-02-16 00:01:42.591 ERROR cinder.volume.manager [req-8134a4d7-53f8-4ada-b4b5-4d96d7cad4bc None None] Error encountered during initialization of driver: RBDDriver 2014-02-16 00:01:42.592 ERROR cinder.volume.manager [req-8134a4d7-53f8-4ada-b4b5-4d96d7cad4bc None None] Bad or unexpected response from the storage volume backend API: error connecting to ceph cluster 2014-02-16 00:01:42.592 TRACE cinder.volume.manager Traceback (most recent call last): 2014-02-16 00:01:42.592 TRACE cinder.volume.manager File "/opt/stack/cinder/cinder/volume/manager.py", line 190, in init_host 2014-02-16 00:01:42.592 TRACE cinder.volume.manager self.driver.check_for_setup_error() 2014-02-16 00:01:42.592 TRACE cinder.volume.manager File "/opt/stack/cinder/cinder/volume/drivers/rbd.py", line 267, in check_for_setup_error 2014-02-16 00:01:42.592 TRACE cinder.volume.manager raise exception.VolumeBackendAPIException(data=msg) 2014-02-16 00:01:42.592 TRACE cinder.volume.manager VolumeBackendAPIException: Bad or unexpected response from the storage volume backend API: error connecting to ceph cluster Here is the content of my /etc/ceph in openstack node: ashish@ubuntu:/etc/ceph$ ls -lrt total 16 -rw-r--r-- 1 cinder cinder 229 Feb 15 23:45 ceph.conf -rw-r--r-- 1 glance glance 65 Feb 15 23:46 ceph.client.glance.keyring -rw-r--r-- 1 cinder cinder 65 Feb 15 23:47 ceph.client.cinder.keyring -rw-r--r-- 1 cinder cinder 72 Feb 15 23:47 ceph.client.cinder-backup.keyring I am really stuck and tried a lot.
