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 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 --------------------------------------------------------------------------------------- [Sun Aug 4 13:38:59 2024] drbd_transport_rdma: disagrees about version of symbol __ib_alloc_pd [Sun Aug 4 13:38:59 2024] drbd_transport_rdma: Unknown symbol __ib_alloc_pd (err -22) [Sun Aug 4 13:38:59 2024] drbd_transport_rdma: disagrees about version of symbol rdma_resolve_addr [Sun Aug 4 13:38:59 2024] drbd_transport_rdma: Unknown symbol rdma_resolve_addr (err -22) [Sun Aug 4 13:38:59 2024] drbd_transport_rdma: disagrees about version of symbol rdma_reject [Sun Aug 4 13:38:59 2024] drbd_transport_rdma: Unknown symbol rdma_reject (err -22) [Sun Aug 4 13:38:59 2024] drbd_transport_rdma: disagrees about version of symbol rdma_disconnect [Sun Aug 4 13:38:59 2024] drbd_transport_rdma: Unknown symbol rdma_disconnect (err -22) [Sun Aug 4 13:38:59 2024] drbd_transport_rdma: disagrees about version of symbol __rdma_create_kernel_id [Sun Aug 4 13:38:59 2024] drbd_transport_rdma: Unknown symbol __rdma_create_kernel_id (err -22) [Sun Aug 4 13:38:59 2024] drbd_transport_rdma: disagrees about version of symbol rdma_resolve_route [Sun Aug 4 13:38:59 2024] drbd_transport_rdma: Unknown symbol rdma_resolve_route (err -22) [Sun Aug 4 13:38:59 2024] drbd_transport_rdma: disagrees about version of symbol rdma_bind_addr [Sun Aug 4 13:38:59 2024] drbd_transport_rdma: Unknown symbol rdma_bind_addr (err -22) [Sun Aug 4 13:38:59 2024] drbd_transport_rdma: disagrees about version of symbol rdma_create_qp [Sun Aug 4 13:38:59 2024] drbd_transport_rdma: Unknown symbol rdma_create_qp (err -22) [Sun Aug 4 13:38:59 2024] drbd_transport_rdma: disagrees about version of symbol rdma_listen [Sun Aug 4 13:38:59 2024] drbd_transport_rdma: Unknown symbol rdma_listen (err -22) [Sun Aug 4 13:38:59 2024] drbd_transport_rdma: disagrees about version of symbol rdma_destroy_qp [Sun Aug 4 13:38:59 2024] drbd_transport_rdma: Unknown symbol rdma_destroy_qp (err -22) [Sun Aug 4 13:38:59 2024] drbd_transport_rdma: disagrees about version of symbol __ib_create_cq [Sun Aug 4 13:38:59 2024] drbd_transport_rdma: Unknown symbol __ib_create_cq (err -22) [Sun Aug 4 13:38:59 2024] drbd_transport_rdma: disagrees about version of symbol ib_destroy_cq_user [Sun Aug 4 13:38:59 2024] drbd_transport_rdma: Unknown symbol ib_destroy_cq_user (err -22) [Sun Aug 4 13:38:59 2024] drbd_transport_rdma: disagrees about version of symbol rdma_connect [Sun Aug 4 13:38:59 2024] drbd_transport_rdma: Unknown symbol rdma_connect (err -22) [Sun Aug 4 13:38:59 2024] drbd_transport_rdma: disagrees about version of symbol ib_modify_qp [Sun Aug 4 13:38:59 2024] drbd_transport_rdma: Unknown symbol ib_modify_qp (err -22) [Sun Aug 4 13:38:59 2024] drbd_transport_rdma: disagrees about version of symbol rdma_destroy_id [Sun Aug 4 13:38:59 2024] drbd_transport_rdma: Unknown symbol rdma_destroy_id (err -22) [Sun Aug 4 13:38:59 2024] drbd_transport_rdma: disagrees about version of symbol rdma_accept [Sun Aug 4 13:38:59 2024] drbd_transport_rdma: Unknown symbol rdma_accept (err -22) [Sun Aug 4 13:38:59 2024] drbd_transport_rdma: disagrees about version of symbol ib_dealloc_pd_user [Sun Aug 4 13:38:59 2024] drbd_transport_rdma: Unknown symbol ib_dealloc_pd_user (err -22) --------------------------------------------------------------------------------------- Could you all guide me?
