Hi Zhiteng,

May what I said in the last mail is confused,
What I want to ask is that, can we use more than one nova-scheduler service in one cluster? is it stable enough to be used in the production environment?
Because I want to make the availability of scheduler service higher.

thanks!

Multi-scheduler was there for the days when Nova has to deal with both 
request for instance and volume.  If you are using a version of Nova 
which still has nova-volume, I think multi-scheduler is a must.  And 
there are two sub config option for Nova: 
http://docs.openstack.org/folsom/openstack-compute/admin/content/ch_scheduling.html 
scheduler_driver=nova.scheduler.multi.MultiScheduler 
volume_scheduler_driver=nova.scheduler.chance.ChanceScheduler 
compute_scheduler_driver=nova.scheduler.filter_scheduler.FilterScheduler 

But if you are using trunk version Nova, scheduler_driver should use 
'nova.scheduler.filter_scheduler.FilterScheduler' directly.
