Hi all,

  I'd like to start discussion on whether the servicegroup in Cinder is 
necessary.
 
  Recently, cinder can only support db driver, and doesn't have 
servicegroup concept.
  our team wants to implement the servicegroup feature using on tooz[1] 
library. Like nova[2], when the state of service is required, it can be 
got through servicegroup.
 
  Besides, due to the cinder-volume-active-active-support[3] merged, we 
think it makes the Service Group do more. 
 
  Before the cinder-volume-active-active-support was proposed, Cinder has 
no concept of cluster. Therefore, we have a doubt that, if without 
cinder-volume-active-active-support, is it necessary to add feature of 
servicegroup?
 
  Any comments or suggestions?
