Hello Team, I have configured ceph as a multibackend for openstack.
I have created 2 pools . 1. Volumes (replication size =3 ) 2. poolb (replication size =2 ) Below is the details from /etc/cinder/cinder.conf enabled_backends=rbd-ceph,rbd-cephrep [rbd-ceph] volume_driver=cinder.volume.drivers.rbd.RBDDriver rbd_pool=volumes volume_backend_name=ceph rbd_user=volumes rbd_secret_uuid=34c88ed2-1cf6-446d-8564-f888934eec35 volumes_dir=/var/lib/cinder/volumes [rbd-cephrep] volume_driver=cinder.volume.drivers.rbd.RBDDriver rbd_pool=poolb volume_backend_name=ceph1 rbd_user=poolb rbd_secret_uuid=d62b0df6-ee26-46f0-8d90-4ef4d55caa5b volumes_dir=/var/lib/cinder/volumes1 when I am attaching a volume to a instance I am getting "DeviceIsBusy: The supplied device (vdb) is busy" error. Please let me know how to correct this..
