如果既要开启kmem accounting又不想对所在的memory cgroup的kmem进行限制,可按如下方式设置: 先往memory.kmem.limit_in_bytes写入一个不为RESOURCE_MAX的任意非负数值开启kmem accounting功能 echo 0 > memory.kmem.limit_in_bytes 再对memory.kmem.limit_in_bytes写入-1值,内核将-1值转为RESOURCE_MAX写入memory.k...

当你开启了kmem 机制,具体体现在 memory.kmem.limit_in_bytes 这个文件上: /sys/fs/cgroup/memory/kubepods/pod632f736f-5ef2-11ea-ad9e-fa163e35f5d4/memory.kmem.limit_in_bytes 实际使用中,我们一般将 memory.kmem.limit_in_bytes 设置成大于 memory.limit_in_bytes,从而只限制应用的总内存使用。 kmem ...

The PR referred totorvalds/linux@0158115f702b, which deprecatedmemory.kmem.limit_in_bytesin kernel 5.4, but the PR also removed support formemory.kmem.tcp.limit_in_bytes. Looking at the Linux kernel, there's no mention (yet) of this option being deprecated as well (but it could be an ...
系统: Ubuntu 18.04.2 LTS内核版本: 4.15.0-50-generic 在/sys/fs/cgroup/memory建了一个目录my-test,然后想设置内存限额,写文件sh -c "echo 1M > memory.limit_in_bytes",发生错误
memsw,即 memory+swap ,memory.memsw.limit_in_bytes用于限制其大小 比如:假设系统一个共拥有4GB的swap空间,如果一个task申请了6GB的内存,但是其内存限制为2GB,此时他将会占用4GB全部的swap空间。此时,如果设置memory.memsw.limit_in_bytes=3GB,就会避免这中swap被占满的情况,通过设定memory.memsw.limit_in_bytes可...
When we created the Docker container, we didn’t setmemory.kmem.limit_in_bytes. But why was kmem insufficient? To determine whethermemory.kmem.limit_in_byteswas set, we went to the cgroup memory controller to check the container’s kmem information. The kmem statistics were enabled, and the...
