Hi Xiaoguang, You will have to download the source from git like explained on: http://ceph.newdream.net/wiki/Rbd But the module will not compile against 2.6.34, only against 2.6.35 There is a rbd-backport branch in "ceph-client-standalone.git", but i'm not sure how up to date that one is. If you want to test RBD, i would recommend upgrading to 2.6.35.
