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
