We have migrated our Windows 2016 Cluster from Mitaka to Newton. Everything is fine now, in one of our 2 region, the Cinder service is not working (that's fine with the same configuration in the other region). At the start up, the service is starting correctly but that's not possible to create a new volume. In the log the only thing is that it writes "Exception during mounting [Errno 11001] No address associated with hostname". The UNC path is working with the account used to mount it. We have also seen that the mnt folder is not created.

I still have no explanation for this issue... I tryied to replace the server name by its IP on a local share (not a SOFS one), but I always have the same. Our other cluster in an other region is worknig fine with the same conficuration. Tryied to un-install and reinstall but was still failling.

We had some issues as well because of eventlet monkey patching the getaddrinfo function, using dnspython as a replacement, which has some bugs (e.g. not parsing the host dns settings correctly).

Depending on your eventlet version, you should be able to avoid having it replace the getaddrinfo function. You can simply set the following env variable:



This will most probably be included in the MSIs as well.

I am not sure we can consider that as an answer, but I get my problem resolved.

I have revert back the getaddrinfo function in C:\Program Files\Cloudbase Solutions\OpenStack\Cinder\Python27\lib\site-packages\eventlet\support\ to the Python default. It seems there is a bug there. This function is which working on one of my cluster and not the other.
