I cannot recreate that "rbd feature disable" error using a master branch build from yesterday. Can you still reproduce this where your rbd CLI can create a data pool image but cannot access the image afterwards?
As for how to run against a librbd-backed client, it depends on what your end goal is. QEMU and fio are just two examples of applications that directly utilize librbd. _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
