从nova-volume迁移到cinder的一些提示-优快云博客

邮件列表上看到的，估计以后得用上，记录下，原文内容如下：

Hi Ahmed -

We don't have a specific Cinder install guide, but this wiki page
gives guidance:
http://wiki.openstack.org/MigrateToCinder

Specific to nova.conf:

set the correct volume api class in nova.conf
volume_api_class=nova.volume.

cinder.API disable the nova-volume-api in enabled apis in /etc/nova/nova.conf sed -i "s/osapi_volume,// /etc/nova/nova.conf", if you do not have enabled_apis set explicitly set it to enabled_apis=ec2,osapi_compute,metadata as osapi_volume is included by default Hope this helps.
