Icehouse Cluster mode Drivers

pravinp — Thu, 05 Jun 2025 05:36:18 GMT

I am using 3 nodes setup and cinder is been installed on controller.

Problem is only when creating volume. It end up with an error on GUI and Cli.

Hi Pravinp,

I think the problem lies in your cinder.conf file. You stated you have the following line:

netapp_server_hostname=data lif ip address

However, netapp_server_hostname needs to be the IP or hostname of the management interface, not the data interface. Preferably it should be the cluster address, though a vserver management address can be used (with some limits on functionality).

Re: Icehouse Cluster mode Drivers

pravinp — Tue, 13 May 2014 11:38:59 GMT

Thanks..

I did tried with both, Below is the ip address details. When i change it to cluster_mgmt i get errors on cinder-scheduler.log. While creating the volume same status error on gui and cli

Are you restarting the cinder-volume and cinder-scheduler processes after you change the cinder.conf file?

Can you capture the cinder-volume.log output during the startup phase?

Sorry, ignore the request for cinder-volume.log start up... I see that in the above post. Can you provide the contents of your nfs shares file (/etc/cinder/netapp.conf)

It looks like your NFS export in the netapp.conf is pointing to your cluster mgmt interface. This one should point to the data interface.

The driver config should point to mgmt interface, the shares config should point to data interface.
