Hi,
I’ve noticed that in the high-availability guide, it is not
recommended to run cinder-volume in an active-active configuration.
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currently rather out of date.
However, I have built an active-passive setup that uses keepalived
and a virtual IP to redirect API traffic to only one controller at a
time.
Yes, this is a fairly common deployment trick.
In such a configuration, would I still need to have only one
cinder-volume service running at a time?
Yes, otherwise it's not active-passive ;-)
Sorry for the slow reply!
