同时近期该机器出现了某个存储卷失效的问题，不知道是何原因

本来想安装rdma的组件，参考https://blog.csdn.net/ibless/article/details/121663751 ，
输入了sudo ./mlnxofedinstall --add-kernel-support这一步之后报错
之后发现dpdk的收包功能失效，出现了以下错误
EAL: Detected 32 lcore(s)
EAL: Detected 2 NUMA nodes
EAL: Multi-process socket /var/run/dpdk/rte/mp_socket

之后尝试按照该方法安装MLNX就出错了

MLNX版本下载，直接wget

https://content.mellanox.com/ofed/MLNX_OFED-5.4-3.6.8.1/MLNX_OFED_LINUX-5.4-3.6.8.1-ubuntu20.04-x86_64.tgz

然后解压缩，安装

/home/zju/Downloads/MLNX_OFED_LINUX-5.4-3.6.8.1-ubuntu20.04-x86_64

tar -xvzf

sudo ./mlnxofedinstall --dpdk

然后按照他输出的提示restart

/etc/init.d/openibd restart

该问题待解决，可能可以参考https://forums.developer.nvidia.com/t/failed-to-install-mlnx-ofed-kernel-dkms-deb-with-version-4-9-4-1-7-0/205889
或者这个

更新，安装5.8版本已解决：

去NVIDA官网看一下，选择另一个合适的版本
https://network.nvidia.com/products/infiniband-drivers/linux/mlnx_ofed/
我是ubuntu20.04系统，所以
下载wget https://content.mellanox.com/ofed/MLNX_OFED-5.8-3.0.7.0/MLNX_OFED_LINUX-5.8-3.0.7.0-ubuntu20.04-x86_64.tgz，并解压
5.8新版本的驱动
然后对老版本5.4目录下运行

然后在5.8目录下运行
./mlnxofedinstall --add-kernel-support

发现失败
然后再运行 ./mlnxofedinstall --dpdk

成功
然后运行/etc/init.d/openibd restart
失败，原因如下：

rmmod: ERROR: Module ib_uverbs is in use by: irdma

意思就是，内核模块 ib_uverbs被irama使用，所以可以参考
https://blog.csdn.net/qq_32949893/article/details/108402550

运行 sudo modprobe -r irdma ib_uverbs，然后再运行/etc/init.d/openibd restart，就可以了，如图所示

安装完成
