Anyone saw the same issue as below?
We are trying to test the multi backend feature with two RBD pools on Grizzly
release. At this point, it seems that rbd.py does not take separate cephx users
for the two RBD pools for authentication as it defaults to the single ID
defined in /etc/init/cinder-volume.conf, which is documented here with "env
CEPH_ARGS="--id volume"
http://ceph.com/docs/master/rbd/rbd-openstack/#configuring-cinder-nova-volume
It seems to us that rbd.py is ignoring the separate "rbd_user=" configuration
for each storage backend section,
[svl-stack-mgmt-openstack-volumes-2]volume_driver=cinder.volume.drivers.rbd.RBDDriverrbd_pool=stack-mgmt-openstack-volumes-2rbd_user=stack-mgmt-openstack-volumes-2rbd_secret_uuid=e1124cad-55e8-d4ce-6c68-5f40491b15efvolume_backend_name=RBD_CINDER_VOLUMES_3
Here is the error from cinder-volume.log,
