Hi, I am trying to use ceph with RDMA. I have a few questions.
1. Is there a prebuilt package that has rdma support or the only way to try ceph+rdma is to checkout from github and compile from scratch? 2. Looks like there are two ways of using rdma - xio and async+rdma. Which is the recommended approach? Also, any insights on the differences will be useful as well. 3. async+rdma seems to have lot of recent changes. Is 11.2.0 expected to work for async+rdma? As when I compiled 11.2.0 it fails with following error [ 81%] Built target rbd /mnt/ceph_compile/ceph/build/lib/libcephfs.so: undefined reference to `ibv_free_device_list' /mnt/ceph_compile/ceph/build/lib/libcephfs.so: undefined reference to `ibv_get_cq_event' /mnt/ceph_compile/ceph/build/lib/libcephfs.so: undefined reference to `ibv_alloc_pd' /mnt/ceph_compile/ceph/build/lib/libcephfs.so: undefined reference to `ibv_close_device' /mnt/ceph_compile/ceph/build/lib/libcephfs.so: undefined reference to `ibv_destroy_qp' /mnt/ceph_compile/ceph/build/lib/libcephfs.so: undefined reference to `ibv_modify_qp' /mnt/ceph_compile/ceph/build/lib/libcephfs.so: undefined reference to `ibv_get_async_event' ***snipped*** Link Error: Ceph FS library not found src/pybind/cephfs/CMakeFiles/cython_cephfs.dir/build.make:57: recipe for target 'src/pybind/cephfs/CMakeFiles/cython_cephfs' failed make[2]: *** [src/pybind/cephfs/CMakeFiles/cython_cephfs] Error 1 CMakeFiles/Makefile2:4015: recipe for target 'src/pybind/cephfs/CMakeFiles/cython_cephfs.dir/all' failed make[1]: *** [src/pybind/cephfs/CMakeFiles/cython_cephfs.dir/all] Error 2 make[1]: *** Waiting for unfinished jobs....
