As of rhel7, the rdma stack is no longer restartable. The rdma stack is now a 1-way operation. When udev detects rdma capable hardware, the stack is automatically started. There is no method to remove the stack items except to manually shut down every rdma using application and then down all the IPoIB interfaces, RDS rdma transport, NFS rdma transport, iSER, iSER target, SRP, SRP target, and anything else that uses the rdma devices, then you can manually remove the modules from the kernel. This action was taken because the rdma stack was deemed to be at a production level, which means it should not need to be restarted under normal circumstances. This brings the rdma stack more in line with all the other kernel stacks that need more than just a simple modprobe to run (such as the SCSI stack, or FCoE stack, etc), all of which are non-restartable. |
