Hi,

Using the SMB cinder driver on a single file server is pretty self explanatory.

However how does it work with a cluster? Like a Scale-out-File-Server?

I presume I need to install it across all the cluster nodes but how does the cinder service distinguish between the different nodes and understand it is a clustered system?

I can't find much information anywhere about how the SMB cinder driver is used in this scenario.

Hi,

You can deploy Cinder on one of the SOFS nodes.

Cinder itself has a notion of clusters, supporting Active-Active deployments, but this is a new work-in-progress feature, which we do not support at the moment.

We encourage configuring the Cinder service as a Windows clustered service. This means that in case of a failure, the service will be automatically moved to a different node within the cluster. We recommend configuring the Cinder service to use the cluster name as a hostname, when reporting back to the scheduler in order to remain consistent after a service failover.

We're working on updating the documentation (which at the moment is quite out of date), emphasizing this scenario.

Edit: Updated docs:

Can I find documentation on how to do this? I'm also desperately searching for any sort of documentation, like a list of config parameters and their respective counterparts in Openstack. The wiki is also basically empty, nothing in github - at least I can't find it. Can you help me?
