Description

Hi,

It seems there is a bug or maybe on the documentations mentioned on http://ceph.com/docs/master/rbd/rbd-openstack/#configure-openstack-to-use-ceph under Configuring Glance, as I am using a Juno version using CentOS 7. It mentioned to use "stores = rbd" but when I run it the openstack-glance-api would not start. I even tried using the prior to Juno style "default_store = rbd" but same issue.

It is only working when you use:

default_stores=rbd

or using the long name

default_stores=glance.store.rbd.Store

please note with 's' at the last.

Thanks.

I found this is not a bug exactly as it only have lacking line under the DEFAULT section that you should put rbd in the default_store. This is the final configuration that is working fine, and by default using ceph cluster to store the images. (note ... signify some lines)

[DEFAULT]
...
default_store=rbd
...
show_image_direct_url=True
...
[glance_store]
stores = rbd
rbd_store_pool = images
rbd_store_user = glance
rbd_store_ceph_conf = /etc/ceph/ceph.conf
rbd_store_chunk_size = 8

But if you go back to which you store the images locally.

[DEFAULT]
...
default_store=file
...
[glance_store]
#stores = rbd  #This time uncomment; as per email problems occur
rbd_store_pool = images
..
