Hi Sylvain, Great to know that you found how to solve your issue.
Thanks for reporting that you found the Grizzly doc confusing. In fact, the Grizzly release introduced the multi-backend feature. This feature allows to have more than one backend on a same compute (ie, to be able to have several cinder-volume running on a same compute). This feature is not available in Folsom: you can only run one cinder-volume per compute (in that case, if you want to manage several backends, you have to have several computes). Thanks a lot for your remarks, Jérôme On Fri, May 31, 2013 at 1:55 PM, Sylvain Bauza <sylvain.ba...@digimind.com>wrote: > Thanks but it didn't match my needs.
