安装 Nvidia OFED 驱动¶
本文将介绍如何通过以 Kubernetes 和 手动 的方式在节点安装英伟达 OFED 驱动.
环境检查¶
-
请确保主机具备 Mellanox 系列网卡，可通过在主机终端执行以下命令确认:
$ lspci -nn | grep Eth | grep Mellanox 3b:00.0 Ethernet controller [0200]: Mellanox Technologies MT27800 Family [ConnectX-5] [15b3:1017] 3b:00.1 Ethernet controller [0200]: Mellanox Technologies MT27800 Family [ConnectX-5] [15b3:1017]以上输出表示主机具备两张 Mellanox 系列网卡, 其型号是 ConnectX-5。
-
确认主机是否已经正确安装 OFED 驱动
以上输出说明当前主机已经安装 OFED 驱动，如果提示命令不存在则说明未安装。如果有以上输出进一步检查 RDMA 设备是否正确识别:
$ rdma link show link mlx5_0/1 state ACTIVE physical_state LINK_UP netdev enp4s0f0np0 link mlx5_1/1 state ACTIVE physical_state LINK_UP netdev enp4s0f1np1 $ ibdev2netdev mlx5_0 port 1 ==> enp4s0f0np0 (Up) mlx5_1 port 1 ==> enp4s0f1np1 (Up)以上输出说明该主机的 RDMA 环境已经就绪。否则先检查网卡的物理状态（比如是否正常接入到交换机等等）。 如果物理链路没问题，按照下面的步骤安装 OFED 驱动。
安装驱动¶
主机的操作系统不同，安装的方式也所不同。为了尽量满足不同的环境安装驱动，下面分别介绍通过 Kubernetes 和 手动两种方式安装 OFED 驱动。
通过 Kubernetes DaemonSet 安装¶
我们可以通过在集群中创建一个 DaemonSet, 由这个 DaemonSet 来帮助安装驱动，但需要注意以下几点事项:
-
目前支持镜像列表只支持 Ubuntu22.04、Ubuntu20.04、Ubuntu18.04 以及 Centos8、RHEL8、RHEL9 系列的操作系统版本。 并且只支持 x86 架构。对于其他操作系统和架构，可按照手动安装 OFED 驱动章节。
OS 内核版本 镜像名称 ubuntu22.04 5.15 daocloud.io/nvidia/mellanox/mofed:23.10-0.5.5.0-ubuntu22.04-amd64 ubuntu20.04 5.4 daocloud.io/nvidia/mellanox/mofed:23.10-0.5.5.0-ubuntu22.04-amd64 ubuntu18.04 4.15 daocloud.io/daocloud/mellanox-mofed:23.07-0.5.0.0-ubuntu18.04-amd64 RHEL9 5.14.0 daocloud.io/daocloud/mellanox-mofed:23.10-0.5.5.0-rhel9.0-amd64 RHEL8/Centos8 4.18.0 daocloud.io/daocloud/mellanox-mofed:23.10-0.5.5.0-rhel8.8-amd64 -
集群不同节点的操作系统或架构可能是不同的，同一个镜像可能无法适用于集群所有节点。这种情况下， 我们应该确保 Pod 运行在指定的节点。否则因为节点操作系统和架构的不同而导致安装驱动失败。
下面是 DaemonSet 的部署清单文件，注意修改 nodeSelector 字段以确保 Pod 调度到需要安装驱动的节点上：
这里以节点的操作系统为 Ubuntu22.04，架构为 x86 为例：

Note
创建后可通过查看 mofed Pod 的日志查看驱动安装过程
如果安装驱动失败，Pod 会不断重启尝试重新安装驱动。
如果安装成功，Pod 将会无限期 Sleep, 可进入到 Pod 执行 ofed_info 查看驱动安装情况。
手动安装¶
对于无法通过 Kubernetes 安装驱动的场景: 比如镜像不支持等。我们可以选择手动方式安装:
-
检查主机操作系统和版本和 CPU 架构
Static hostname: 10-20-1-20 Icon name: computer-server Chassis: server Machine ID: 12998dac94434e66aaf6546cb42b9c93 Boot ID: 852a0d1c0382438a98e84591f322fc36 Operating System: Ubuntu 22.04.3 LTS Kernel: Linux 5.15.0-91-generic Architecture: x86-64 Hardware Vendor: Lenovo Hardware Model: -_7X06CTO1WW_- -
在英伟达官网下载主机架构、操作系统对应的 OFED 驱动版本：
Note
注意目前需要匹配到主机的发行版、架构以及操作系统版本。
如果想要下载早期版本，请点击 Archive Version 切换。
-
本文以下载 iso 文件为例，下载文件并上传到主机。挂载到
/mnt路径并执行安装命令。root@10-20-1-20:~/install# mount MLNX_OFED_LINUX-23.10-1.1.9.0-ubuntu22.04-x86_64.iso /mnt/ mount: /mnt: WARNING: source write-protected, mounted read-only. root@10-20-1-20:/mnt# ./mlnxofedinstall --with-nvmf --with-nfsrdma --all Logs dir: /tmp/MLNX_OFED_LINUX.86055.logs General log file: /tmp/MLNX_OFED_LINUX.86055.logs/general.log Below is the list of MLNX_OFED_LINUX packages that you have chosen (some may have been added by the installer due to package dependencies): ofed-scripts mlnx-tools mlnx-ofed-kernel-utils mlnx-ofed-kernel-dkms iser-dkms isert-dkms srp-dkms mlnx-nfsrdma-dkms mlnx-nvme-dkms rdma-core libibverbs1 ibverbs-utils ibverbs-providers libibverbs-dev libibverbs1-dbg libibumad3 libibumad-dev ibacm librdmacm1 rdmacm-utils librdmacm-dev mstflint ibdump libibmad5 libibmad-dev libopensm opensm opensm-doc libopensm-devel libibnetdisc5 infiniband-diags mft kernel-mft-dkms perftest ibutils2 ibsim ibsim-doc ucx sharp hcoll knem-dkms knem openmpi mpitests dpcp srptools mlnx-ethtool mlnx-iproute2 rshim ibarr This program will install the MLNX_OFED_LINUX package on your machine. Note that all other Mellanox, OEM, OFED, RDMA or Distribution IB packages will be removed. Those packages are removed due to conflicts with MLNX_OFED_LINUX, do not reinstall them. Do you want to continue?[y/N]:Note
- 输入 y 开始安装驱动，大概需要 20 分钟，请耐心等待
- '--with-nvmf' 和 '--with-nfsrdma' 是可选参数，按需配置。可输入 --help 查看详情

如果您的网卡固件版本低于当前驱动固件版本，则会自动更新固件。 当驱动安装成功后，提示重启驱动
/etc/init.d/openibd restart...

重新启动驱动
$ /etc/init.d/openibd restart Unloading HCA driver: [ OK ] Loading HCA driver and Access Layer: [ OK ]如果执行失败，可参考以下错误：
-
由于 opensm 仍然在运行导致重启驱动失败。
$ /etc/init.d/openibd restart Please stop "opensm" and all applications running over InfiniBand. Please stop the following applications still using Infiniband devices: opensm(1632) user root is using device issm0 opensm(1632) user root is using device umad0 Error: Cannot unload the Infiniband driver stack due to the above issue(s)! Once the above issue(s) resolved, run: # /etc/init.d/openibd restart手动执行
systemctl stop opensmd可修复这个问题。 -
内核 module 正被引用，无法移除导致重启失败
$ /etc/init.d/openibd restart Unloading mlx_compat [FAILED] rmmod: ERROR: Module mlx_compat is in use by: nvme_core nvme_fabrics通过 lsmod 查看 module: nvme_core 和 nvme_fabrics 之间相互依赖关系，按顺序依次卸载这些 modules 后，解决这个问题。
