<DIV><FONT color=#000000 size=3 face=宋体>Hi Zhiteng,</FONT></DIV>
<DIV> </DIV>
<DIV>May what I said in the last mail is confused,</DIV>
<DIV>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?</DIV>
<DIV>Because I want to make the availability of scheduler service higher.</DIV>
<DIV> </DIV>
<DIV>thanks!</DIV>

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