Does anybody know something about how to configure ceph storage to be used by Hyper-V nodes as backend storage? I have Openstack Liberty environment. There are 2 hyper-v compute nodes (cloudbase nova service installed). When trying to attach volume to the instance on hyperv there is error:

File "C:\Program Files (x86)\Cloudbase Solutions\OpenStack\Nova\Python27\lib\site-packages\hyperv\nova\volumeops.py", line 85, in getvolumedriver 2016-08-02 16:15:23.851 1776 ERROR nova.compute.manager [instance: 7fc759d0-9e76-4611-8cd1-780c99fd657c] raise exception.VolumeDriverNotFound(drivertype=driver_type) 2016-08-02 16:15:23.851 1776 ERROR nova.compute.manager [instance: 7fc759d0-9e76-4611-8cd1-780c99fd657c] VolumeDriverNotFound: Could not find a handler for rbd volume.

Need some RBD proxy. but can't find anything.

Thanks.

Hi,

The Hyper-V Nova driver does not support RBD as there is not Ceph client for Windows yet. The only supported protocols are iSCSI, FC and SMB.

Although having a proxy re-exporting the rbd volumes via iSCSI would work (with some considerable overhead), this scenario is not supported. If really necessary, I think you could achieve this by writing a custom Cinder driver.

Regards, Luci
