Open Stack

Thanks for the answer.

My use case is for a file-hosting software system like « Seafile »  which can use a ceph backend (swift too but we don’t deploy swift on our infra).

Our network configuration of our infra is identical as your OSA documentation. So, on our compute node we have two bonding interface (bond0 and bond1).
The ceph vlan is actually propagate on bond0 (where is attach br-storage) to have ceph backend for our openstack.
And on bond1, among other, we have br-vlan for ours vlans providers.

If i understood correctly, the solution is to propagate too on our switch the ceph vlan on bond1, and create by neutron the provider network to be reachable in the tenant by our file-hosting software.

For security issues, using neutron rbac tool to share only this provider network to the tenant in question, could be sufficient ?

I’m all ears ;-) if you have another alternative.

Regards,
Fabrice
