What options are you using for the NFS client on the controllers side? There are some recommended settings that Netapp can provide.

Hello,

I've just updated my kolla wallaby with latest images. When I create volume from image on ceph it works.

When I create volume from image on nfs netapp ontap, it does not work.

The following is reported in cinder-volume.log:

Any help please ?
