Hi Xiaoguang, No, the RBD code will only compile against 2.6.35, so your options are: * Get a 2.6.35 kernel for Fedora 13 somewhere and compile RBD against that * Compile a 2.6.35 kernel for your system If you choose this first, you only have to run "make" in fs/ceph (with ofcourse the right paramaters). I've updated the Wiki a bit, these was no reference of you having to chdir to fs/ceph Wido On Mon, 2010-08-02 at 13:41 +0800, Xiaoguang Liu wrote: > I do want to use the latest kernel.
