Open Stack

Work is underway in cinder to allow active/active HA (or
active/active/active/... for the truly paranoid) volume managers for a
single backend, for remote backends that can support it. This is
likely to take most of the Kilo cycle to finish.

You can use pacemaker or other H/A technology (I suspect some sort of
monitored VM is the VMWare equivalent) to improve the availability of
cinder-volume in the current release.
