Hello All, I have a 2-node cluster on which I am trying to load the drdb_transport_rdma.ko modules.
The nodes have - - Rocky Linux 9.1 (Kernel 5.14.0-162.23.1) - NVIDIA/Mellanox ConnectX-5 EN 100GB NIC - MLNX_OFED_LINUX-23.10-3.2.2.0-rhel9.1-x86_64 drivers - DRBD 9.2.3 (compiled on the same machine) I have connected the 100G Ethernet (RoCE) ports back-to-back with a short DAC cable. Tests with perftest tools (ib_send_bw and ib_read_bw) show proper connectivity. RoCE is working properly. But, I get the following error when I try to load the drdb_transport_rdma.ko module --------------------------------------------------------------------------------------- Hello All, I have a 2-node cluster on which I am trying to load the drdb_transport_rdma.ko modules.
