Hi, Thanks for your reply. I saw that ceph already has the Iscsi Gateway. Does the cinder project have such a driver? Gorka Eguileor <geguileo@redhat.com> 于2019年5月10日周五 下午6:39写道：

I'm using ceph as cinder backend, RBD drvier.
Hi,
If you are using a Ceph/RBD cluster then there are some things to take into consideration:
- You need to have the ceph-common package installed in the system.
- The images are mounted using the kernel module, so you have to be careful with the features that are enabled in the images.
- If I'm not mistaken the RBD attach using the cinderclient extension will fail if you don't have the configuration and credentials file already in the system.
My ideas the instance should communicate with Openstack platform storage network via the vrouter provided by neutron. The vrouter gateway should communicate with Openstack platform. is or right?
I can't help you on the network side, since I don't know anything about Neutron.
Cheers, Gorka.

Hi, I am looking for a mechanism that can be used for baremetal attach volume in a multi-tenant scenario. In addition we use ceph as the backend storage for cinder.
Can anybody give me some advice?
Hi,
Is this a stand alone Cinder deployment or a normal Cinder in OpenStack deployment?
What storage backend will you be using?
What storage protocol? iSCSI, FC, RBD...?
Depending on these you can go with Walter's suggestion of using cinderclient and its extension (which in general is the best way to go), or you may prefer writing a small python script that uses OS-Brick and makes the REST API calls directly.
Cheers, Gorka.
