Re: Resize data-disk doesn't work after upgrade
Hi, I don't know how RBD works. If there are qcow2 files that you can see, you can check them with qemu-img. If there are no files I think resizing on RBD probably doesn't work since the script that does the resize only supports resizing qcow2 files and CLVM volumes.

[SOLVED] Re: Resize data-disk doesn't work after upgrade
Hi Kirk and all, I managed to resolve the problem, I am now able to resize the volume provided that I follow below steps: - stop the VM; - detach the volume from the VM; - resize the volume; - re-attach the volume; - restart the VM. Both upgrade and downgrade work fine now. Many thanks for your help. Cheers. On Tue, Oct 8, 2013 at 3:19 AM, Kirk Kosinski kirkkosin...@gmail.comwrote: Hi, I don't know how RBD works.
