This is *not* a case of that bug. That LP bug is referring to an issue with the 'nova resize' command and *not* with an instance resizing its own root filesystem. I can confirm that the latter case works perfectly fine in Havana if you have things configured properly. A few questions: 1) What workflow are you using? (Create a volume from an image -> boot from that volume, ceps-backed ephemeral, or some other patch?) 2) What OS/release are you running? I've gotten it to work with recent versions Centos, Debian, Fedora, and Ubuntu. 3) What are you actually seeing on the image? Is the *partition* not being resized at all (as referenced by /proc/partions), or is it just the filesystem that isn't being resized (as referenced by df)?
