Active-active cinder-volume support is still in development, e.g. see

https://blueprints.launchpad.net/cinder/+spec/cinder-volume-active-active-support

I would strongly recommend talking to the Cinder experts to find out
the current state, rather than relying on the HA guide which is
currently rather out of date.

Yes, this is a fairly common deployment trick.

Yes, otherwise it's not active-passive ;-)

Sorry for the slow reply!
