Linux Docker cgroup.procs设备上没有剩余空间

Docker和我的Debian专用服务器出现了一些问题（提供商提供了一些操作系统映像，但没有Docker所需的一些功能，因此我昨天重新编译了Linux内核并激活了所需的功能，我在博客中遵循了一些说明）

现在我很高兴与docker合作成功，我试图创造形象。。。我有一个错误

在debian repos中，我通过docker lxc安装了docker，我跟随了一首tuto。我尝试了另一个解决方案（成功），我将我的source.list

/etc/apt/source.list

从jessie更新为sid，我清除了

docker lxc

，安装了

docker.io

错误改变了。它是

mkdir-p/sys/。。。无法创建目录：访问被拒绝

因此，我在博客中找到了一条评论，我尝试了一种解决方案，那就是评论教程之前添加的这一行：

 ## file /etc/fstab
 # cgroup /sys/fs/cgroup cgroup defaults 0 0

---

然后重新启动服务器。

您不应该删除docker中的cgroup支持。否则，您可能会收到类似于

警告的警告：您的内核不支持内存交换功能，内存交换被丢弃。

当您运行docker容器时

一个简单的命令就可以做到这一点

sudo echo 1 > /sys/fs/cgroup/docker/cgroup.clone_children

如果仍不工作，请运行以下命令并重新启动docker服务：

sudo echo 0 > /sys/fs/cgroup/docker/cpuset.mems
sudo echo 0 > /sys/fs/cgroup/docker/cpuset.cpus

---

查看

du-sk/var

和

sudo fdisk-l

的输出会有帮助。我用你命令的结果更新了我的第一篇帖子。嗨，你能指出关于修改/etc/fstab的文档吗？从fstab中删除cgroup也解决了同样的问题。虽然我不知道为什么。

yum install -y libcgroup libcgroup-devel libcgroup-tools

cgclear
service cgconfig restart

mount -t cgroup none /cgroup

vi /etc/fstab
cgroup /sys/fs/cgroup cgroup defaults 0 0
