[ovirt-devel] Mixed local and shared storage

[David Caro]

Thanks Christopher!

That will force me to have as many gluster storages as hosts? Or it will  allow
to have one gluster setup with each of the hosts accessing to the local storage?

I will investigate, but I'd prefer if I did not have to use any external
service at all (in the end, is just local storage)
