Openstack several NFS volume from the same Cdot but different nodes

Damian_Bento — Wed, 14 Jun 2023 02:14:31 GMT

Hi, guys

I have a silly question. As I far I know cinder is working ok with netapp nfs. For balance reasons I have created a several nfs volumes each per controller.
But I can not select a individual volume in order to create a openstack volumes. Every time that I create a openstack Volume, Openstack use the same netapp NFS volume.
BTW vol1 var/lib/cinder/mnt/284ed7dd9710fcad3e61e80b246f1393 is W/R ok.

Netapp vol connected to nova Controller

I have created a NFS extra_specs, but keeps using same Netapp Vol.

Could you please let me know how you configured these NFS volumes in your cinder.conf file?
