I found cinder havana version is added a new feature about the read-only volume. So I create a volume with setting volume metadata with key="readonly" and value="True", and attached it to an instance. However, it doesn't work. I can write data in volume. Any wrong with my steps? How could I use the read-only volume? Has been multi-attach readonly volume supported? -------------- next part -------------- An HTML attachment was scrubbed...
