Re: Ceph and Openstack

Fortunately Ceph Giant + OpenStack Juno works flawlessly for me.

If you have configured cinder / glance correctly , then after restarting  cinder and glance services , you should see something like this in cinder and glance logs.


Cinder logs : 

volume.log:2015-04-02 13:20:43.943 2085 INFO cinder.volume.manager [req-526cb14e-42ef-4c49-b033-e9bf2096be8f - - - - -] Starting volume driver RBDDriver (1.1.0)


Glance Logs:

api.log:2015-04-02 13:20:50.448 1266 DEBUG glance.common.config [-] glance_store.default_store     = rbd log_opt_values /usr/lib/python2.7/site-packages/oslo/config/cfg.py:2004

api.log:2015-04-02 13:20:50.449 1266 DEBUG glance.common.config [-] glance_store.rbd_store_user    = glance log_opt_values /usr/lib/python2.7/site-packages/oslo/config/cfg.py:2004
api.log:2015-04-02 13:20:50.451 1266 DEBUG glance.common.config [-] glance_store.stores            = ['rbd'] log_opt_values /usr/lib/python2.7/site-packages/oslo/config/cfg.py:2004


If Cinder and Glance are able to initialize RBD driver , then everything should work like charm.

Can you both set Cinder and / or Glance logging to debug and provide some logs? There was an issue with the first Juno release of Glance in some vendor packages, so make sure you're fully updated to 2014.2.2

I am conincidentally going through the same process right now. The best reference I've found is this: http://ceph.com/docs/master/rbd/rbd-openstack/

When I did Firefly / icehouse, this (seemingly) same guide Just Worked(tm), but now with Giant / Juno I'm running into similar trouble  to that which you describe. Everything _seems_ right, but creating volumes via openstack just sits and spins forever, never creating anything and (as far as i've found so far) not logging anything interesting. Normal Rados operations work fine.

Feel free to hit me up off list if you want to confer and then we can return here if we come up with anything to be shared with the group.

All,

Apologies for my ignorance but I don't seem to be able to search an archive. 

I've spent a lot of time trying but am having difficulty in integrating Ceph (Giant) into Openstack (Juno). I don't appear to be recording any errors anywhere, but simply don't seem to be writing to the cluster if I try creating a new volume or importing an image. The cluster is good and I can create a static rbd mapping so I know the key components are in place. My problem is almost certainly finger trouble on my part but am completely lost and wondered if there was a well thumbed guide to integration?

Thanks


Iain
