For RHEL 7 there will be a extra yum repo with a module which supports format 2, so isn't it that that after Firefly we change 'rbd_default_format' to 2? I still see a lot of images being created with format 1 and that will otherwise be hunting us for a long time. I'd vote for making format 2 the default or at least patch the 'rbd' tool to create format 2 images. -- Wido den Hollander 42on B.V. Phone: +31 (0)20 700 9902 Skype: contact42on
