我正在尝试在 BlueData 上运行的 docker 容器内设置一个光泽客户端（docs ）。
根据这篇文章，我修改了每个工作人员和控制器节点上的 BlueData 配置：
$ vi /opt/bluedata/common-install/bd_mgmt/releases/1/sys.config
我添加了 SYS_ADMIN 功能：
{allowed_docker_caps, ["SETPCAP",
"SYS_ADMIN",
...
并重新启动主机。
接下来，我在 BlueData 中配置了一个 Centos 7.x 集群：
- CentOS 7.x 没有预先打包的应用程序或软件
- 图片版本：2.2
- 发行版 ID：bluedata/centos7
然后我 ssh 进入 Centos 容器：
$ ssh -o StrictHostKeyChecking=no -i /Users/me/.ssh/id_rsa centos@x.x.x.x
在容器内，我安装了光泽客户端：
sudo yum install \
kernel \
kernel-devel \
kernel-headers \
kernel-abi-whitelists \
kernel-tools \
kernel-tools-libs \
kernel-tools-libs-devel

但是，当我尝试加载 luster 模块时收到错误消息：

我检查了内核版本：

[bluedata@bluedata-5 ~]$ sudo modprobe -v lustre
insmod /lib/modules/3.10.0-957.21.3.el7.x86_64/extra/ptlrpc.ko.xz

错误信息提示我需要配置网络，所以我尝试了：
[bluedata@bluedata-5 ~]$ sudo modprobe lnet
[bluedata@bluedata-5 ~]$ sudo lnetctl lnet configure
光泽现在加载没有错误：
[bluedata@bluedata-5 ~]$ sudo modprobe -v lustre
