I tried enabling the RDMA support in Ceph Luminous release following this [1] guide. I used the released Luminous bits, and not the Mellanox branches mentioned in the guide. I could see some RDMA traffic in the perf counters, but the ceph daemons were still complaining that they are not able to talk with each other. AFAIK the RDMA support in Ceph is experimental. I would like to know… What is the state of the RDMA code in the Ceph Luminous and later releases? When will it be production ready? Thanks, Nitin [1]: https://community.mellanox.com/docs/DOC-2721 |
