错误：未安装 cgroup 命名空间“freezer”。中止

Question

尝试运行 slurmd：

\n

sudo systemctl start slurmd\n

\n

我显示守护进程的状态，屏幕上显示错误：

\n

我不知道如何解决它。我希望得到你的帮助。我使用 slurm 版本 18.08.05 和 debian 10。

\n

UPD。\n我将 slurm.config 中的 ProctrackType 值更改为 proctrack/linuxproc：

\n

ProctrackType=proctrack/linuxproc\n

\n

一切都是工作。

与文档（man cgroup.conf）不同，参数CgroupMountpoint的默认值不好。

echo CgroupMountpoint=/sys/fs/cgroup >> /etc/slurm-llnl/cgroup.conf

并且您可以重置 ProctrackType 的值。在Debian10.7 slurmd版本上测试：slurm-wlm 18.08.5-2
