解决内核版本问题
启动客户端服务时，可能出现如下错误：
$ systemctl start beegfs-client
Job for beegfs-client.service failed because the control process exited with error code. See "systemctl status beegfs-client.service" and "journalctl -xe" for details.
$ systemctl status beegfs-client.service -l

这是由于没有安装kernel-devel，没有内核头文件引起的。
或者是下面这个错误：

这是BeeGFS 6.18在RHEL 3.10.0-862版本内核上的一个Bug引起的：
在所有节点上安装kernel-3.10.0-693版本的内核和开发包即可解决问题：
