I everybody, I am testing heat stack with a simple template made up of a vm with a root volume and a data volume. The stack works fine. In my second step I changed the stack increasing the data volume size but updating the stack an "expanding error" occurred. I am using cinder nfs volumes. I read the cinder matrix and expansion on nfs should be supported. Is this a storage or a heat issue ? Volume can be expanded with heat stack update ? As far as root volumes are concerned, does heat stack update cause loss of data ? Regards Ignazio -------------- next part -------------- An HTML attachment was scrubbed...
