Hi guys, There is just ms_type = async+rdma in the document, but there are options not mentioned. I get them using osd config show: ceph config show-with-defaults osd.0 | grep rdma ms_async_rdma_buffer_size 131072 ms_async_rdma_cm false ms_async_rdma_device_name ms_async_rdma_dscp 96 ms_async_rdma_enable_hugepage false ms_async_rdma_gid_idx 0 ms_async_rdma_local_gid ms_async_rdma_polling_us 1000 ms_async_rdma_port_num 1 ms_async_rdma_receive_buffers 32768 ms_async_rdma_receive_queue_len 4096 ms_async_rdma_roce_ver 1 ms_async_rdma_send_buffers 1024 ms_async_rdma_sl 3 ms_async_rdma_support_srq true ms_async_rdma_type ib When I checked Ceph github I found these options with_legacy: true. https://github.com/ceph/ceph/blob/main/src/common/options/global.yaml.in - name: ms_async_rdma_device_name type: str level: advanced with_legacy: true - name: ms_async_rdma_enable_hugepage type: bool level: advanced default: false with_legacy: true - name: ms_async_rdma_buffer_size type: size level: advanced default: 128_K with_legacy: true - name: ms_async_rdma_send_buffers type: uint level: advanced default: 1_K with_legacy: true size of the receive buffer pool, 0 is unlimited - name: ms_async_rdma_receive_buffers type: uint level: advanced default: 32_K with_legacy: true max number of wr in srq - name: ms_async_rdma_receive_queue_len type: uint level: advanced default: 4_K with_legacy: true support srq - name: ms_async_rdma_support_srq type: bool level: advanced default: true with_legacy: true - name: ms_async_rdma_port_num type: uint level: advanced default: 1 with_legacy: true - name: ms_async_rdma_polling_us type: uint level: advanced default: 1000 with_legacy: true - name: ms_async_rdma_gid_idx type: int level: advanced desc: use gid_idx to select GID for choosing RoCEv1 or RoCEv2 default: 0 with_legacy: true GID format: "fe80:0000:0000:0000:7efe:90ff:fe72:6efe", no zero folding - name: ms_async_rdma_local_gid type: str level: advanced with_legacy: true 0=RoCEv1, 1=RoCEv2, 2=RoCEv1.5 - name: ms_async_rdma_roce_ver type: int level: advanced default: 1 with_legacy: true in RoCE, this means PCP - name: ms_async_rdma_sl type: int level: advanced default: 3 with_legacy: true in RoCE, this means DSCP - name: ms_async_rdma_dscp type: int level: advanced default: 96 with_legacy: true when there are enough accept failures, indicating there are unrecoverable failures, just do ceph_abort() .
