Hi, I'm deploying a small cluster based on Almalinux9 using a dedicated cluster environment. When deploying infiniband support, the provided Ansible scripts try to launch the rdma service and it fails. In my old CentOS8 cluster, rdma-core provides the rdma service startup file /usr/lib/systemd/system/rdma.service in rdma-core-26.0-8.el8 to launch the rdma service In my new Almalinux9 cluster this file is no more provided by rdma-core-51.0-1.el9 And I'm unable to understand if it is no more necessary ("automagically" activated) or if I need an other package by looking at various documentations and https://github.com/linux-rdma/rdma-core. But I'm not very familiar with this stack as usually it works out of the box (so I never delved deeply into the documentation before) Could someone help me to clarify this ? Thanks Patrick
