According to the user guide, you need to detach a volume before resizing it. You don't have to shut the instance down, though.

If you wish to resize other aspects of the guest (e.g. change the flavor to increase CPU/RAM available) then you need to perform a nova resize on the guest. This operation requires the guest to be shutdown, though a proposal to provide a "live" version of this in a future release exists.
