Unfortunately, I'm not familiar with NetApp so I can just ask for more details, hopefully other users can help you. What exactly do you mean that it fails only sometimes? The stack trace you provided shows the attempt to retype a swap volume, is it always a swap volume when it fails or are other volumes affected, too?

Hi,
since you're retyping a volume, what do the cinder logs reveal?

Hello, sometimes the volume retype from a netapp nfs storage to another netapp nfs storage does not work. I do not know the reason but I think something is going wrong in nova:

Must I try to change some parameters in nova.conf on compute nodes about volume attachment ?
Thanks Ignazio
