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.
