Dear Josh and Travis: I am trying to setup the openstack+ceph environment too, but I am not using devstack. I deploy the glance, cinder, nova, keystone into different servers. All the basic function works fine, I can import image, create volume and create virtual machine. It seems the glance and cinder access ceph block device correctly. (ceph version 0.53)
But when I try to create an volume based on existed images, it failed. I use the command in http://ceph.com/docs/master/rbd/rbd-openstack/ root@glance:~# glance image-list +--------------------------------------+---------------------+-------------+------------------+------------+--------+ | ID | Name | Disk Format | Container Format | Size | Status | +--------------------------------------+---------------------+-------------+------------------+------------+--------+ | cad779fc-c851-4581-ac4d-474c3773bf89 | Ubuntu-Precise-Raw | raw | bare | 2147483648 | active | +--------------------------------------+---------------------+-------------+------------------+------------+--------+ root@glance:~# rbd info -p images cad779fc-c851-4581-ac4d-474c3773bf89 rbd image 'cad779fc-c851-4581-ac4d-474c3773bf89': size 2048 MB in 256 objects order 23 (8192 KB objects) block_name_prefix: rbd_data.28c076755ff format: 2 features: layering root@cinder:~# cinder create --image-id cad779fc-c851-4581-ac4d-474c3773bf89 10 root@cinder:~# cinder list +--------------------------------------+-----------+----------------+------+-------------+--------------------------------------+ | ID | Status | Display Name | Size | Volume Type | Attached to | +--------------------------------------+-----------+----------------+------+-------------+--------------------------------------+ | b8af3932-b27a-41e4-a2cc-082b78083f79 | error | None | 10 | None | | +--------------------------------------+-----------+----------------+------+-------------+--------------------------------------+ Do you ever met this error message? Any suggestion is appreciated. Furthermore, I do not use cephx authentication, therefore, I didn't setup CEPH_ARGS. Is it possible to cause this issue?

Stupidly, I had not looked at those docs. I forgot all about them since they didn't used to be there. I was only using OpenStack docs and not the Ceph ones.
