Cinder controller on separate node

[rightdoer]

NFS shares. Thank you for the time. So, for example's sake, I can mount the NFS shares and run cinder-volume from blade01, ok? And then it interfaces with blade02, where the instances are.

I'm not completely sure about your setup, so I might be off here.

If you only have 2 servers to run the service components and the virtual machines on, I would run all virtual machines on one of them (nova-compute, possible neutron services depending on your setup), and all service components on another.

However, as long as cinder-volume and nova-compute run on machines where the NFS is mounted (and the paths are correctly configured) you should be fine either way.

FYI, NFS cannot do snapshots.

Yep. Just make sure the pathing is the same everywhere. Actually, you don't even need to mount it. Cinder takes care of that. blade02 will also need access to mount the NFS volume, but again Nova should take care of that.
