Hi all,

I have an issue with my glance service.

I run icehouse on ubuntu 14.04.2 LTS in icehouse version 2014.1.5. Glance is setup with RDB backend.

I can :

• image-create
• image-delete
• image-list
• image-show

but i can not glance image-download i got no error just glance client hang. The impact is i can not create new instance out of the same ceph cluster.

I run 2 nova availability zone. One with instance attached to cinder volume in the same ceph cluster and i allow Copy-on-write functionality and another one with only ephemeral instances.

The creation of cinder volume on the same ceph cluster with Copy-on-write works. The creation of new instances where i have to locally download the image on the compute node doesn't work as the glance image-download command stay hang.

After i attempted to create an instance the whole glance-api on port 9292 stay hang. I have to restart the glance-api service to get back to "normal service".

I see no error in the debug log : glance-api.log
