You sould define the volume type related to volume backends. For example, you set lvm backend driver in your cinder.conf like below.
enabled_backends=lvmdriver-1 [lvmdriver-1] volume_group=cinder-volumes volume_driver=cinder.volume.drivers.lvm.LVMISCSIDriver volume_backend_name=LVM you set your volume type in order to connect you lvmdriver-1 backend In your cinder management. # cinder type-create lvm # cinder type-key volume_backend_name=LVM For creating lvm type volume, you specify volume type when you create volume. # volume create 1 --volume-type lvm Cinder can find volume backend using volume-type and backend connectivity. 2014-02-17 15:24 GMT+09:00 Subramanian <subramanian.neelakan...@gmail.com>: > I think you should look at the cinder scheduler code that selects a host > based on the volume type. > https://github.com/openstack/cinder/tree/master/cinder/scheduler. > > BTW, cinder dev tend to hang out on #openstack-cinder channel. > > Thanks, > Subbu > > > On Mon, Feb 17, 2014 at 11:35 AM, iKhan <ik.ibadk...@gmail.com> wrote: > >> Hi All, >> >> I'm just curious on how the manager.py is choosing backend while creating >> volume, I know volume type is set but where is this being processed? >> >> I am sorry if this is a basic question, but didn't got any help from >> #openstack-dev IRC channel so was left without option to post here. >> >> -- >> Thanks, >> IK >> >> _______________________________________________ >> OpenStack-dev mailing list >> OpenStack-dev@lists.openstack.org >> http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev >> >> > > _______________________________________________ > OpenStack-dev mailing list > OpenStack-dev@lists.openstack.org > http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev > >
