[Openstack-operators] Mixed env for nova (ceph for some compute nodes, local disk for the rest): qcow2 or raw images ?

2017-04-05 Thread Massimo Sgaravatto
Hi Currently in our Cloud we are using a gluster storage for cinder and glance. For nova we are using a shared file system (implemented using gluster) for part of the compute nodes; the rest of the compute nodes use the local disk. We are now planning the replacement of gluster with ceph. The ide

Hi Massimo, You can upload the images twice, in both qcow2 and raw format, then create a host aggregate for your "local-disk" compute nodes and set its metadata to match the property you'll set on your qcow2 images. When somebody will start a qcow2 version of the image, it will be scheduled on yo
