tmpfs文件系统是一个虚拟内存文件系统。
使用tmpfs虚拟内存文件系统和绑定挂装（第 3部分）
Using the tmpfs virtual memory filesystem and bind mounts (Part 3)
刚开始这看起来可能有点武断，但请记住tmpfs也是我们知道的“虚拟内存文件系统”。
This might seem a bit arbitrary at first, but remember that tmpfs is also known as the "virtual memory filesystem".
它报告文件系统的所有层的使用率，包括逻辑卷管理器(LVM)、虚拟内存和物理磁盘层。
It reports on all layers of file system utilization, including the Logical Volume Manager (LVM), virtual memory, and physical disk layers.
这阻止必须将加密材料储存在设备的文件系统中，因为加密材料可以在获取时缓存在内存中。
This prevents the crypto material from having to be stored on the appliance's file system, as the material will be cached in memory upon retrieval.
存储的类型有很多种；数据库、文件系统、内存数据和诸如原生目录等持久化设备都是存储。
There are different types of storage; databases, file systems, in-memory data, persistence devices like native directories are but a few examples.
物理参数包括CPU温度、内存与文件系统利用情况、接口利用、电压读数，以及其他物理值。
Physical parameters range from the temperature of CPUs, utilization of memory and file system, interface utilization, and voltage reading, among other physical values.
疲劳系统管理员的无意按键可能会导致文件系统中的文件被删除、整个应用程序被卸载或内存升级烧坏内部硬件。
Inadvertent keystrokes by fatigued system administrators have resulted in files being deleted from file systems, whole applications uninstalled, or memory upgrades frying hardware internals.
下一步，将根文件系统载入内存。
这些库副本将塞满部署这些EAR的文件系统和知识库，并在应用程序启动时填满内存。
You end up with an explosion of copies of these libraries on the file system or repository to which the EARs are deployed and in memory when the applications are started.
我的WAP在内存中有一个只读的文件系统，用于为文件和日志提供服务。
My WAP has a read-write filesystem in memory for work files and logging.
SSI解决方案会修改内核的几乎所有部分：进程管理、文件系统、内存 管理、调度器，等等。通过不加修改地运行内核进程，模拟器简化了部署工作。
SSI solutions modify almost every area of kernel: process management, filesystem, memory management, scheduler, etc. Emulators simplify the deployment by letting the kernel processes run unchanged.
Lucene将输入数据存储在名为逆序索引的数据结构中，该数据结构以索引文件集的形式存储在文件系统或内存中。
Lucene stores the input data in a data structure called an inverted index, which is stored on the file system or memory as a set of index files.
DataPower设备在重启时会自动进行节流(throttle)设置，如内存或文件系统限制。
The DataPower device restarts itself automatically in conjunction with throttle configurations such as memory or file system constraints.
tmpfs文件系统所知道的就是它正在使用某种形式的虚拟内存。
All the TMPFS filesystem knows is that it is using some form of virtual memory.
文件系统加载到内存后，内核执行init进程，该进程现在接管启动过程。
After the file systems have been loaded into RAM, the kernel executes the init process, which now takes over the boot process.
目前，XFS的Linux版本要求XFS文件系统块的大小与平台的内存页面大小相同。
Right now, XFS for Linux requires that the XFS filesystem block size is the same size as the platform's memory page size.
挂载这些文件系统后，init被替换为磁盘上的init,pid为1，并清除内存。
After these file systems have been mounted, init is replaced with init on the disk as PID 1, and the RAM is cleared.
根据图2中的numclient值，可以假设大约45%的内存用于文件系统，即大约45GB；另外的55 GB是工作存储。
Based on the numclient value in Figure 2, you can assume about 45 percent of our memory is being used for filesystems, which would be around 45 GB; the other 55 GB is working storage.
ext3文件系统驱动程序也使用这种方法，存储内存中被修改的块（大小为1K、2K或 4K）的完整副本，以跟踪暂挂的IO操作。
The ext3 filesystem driver also uses this approach and stores complete replicas of the modified blocks (either 1K, 2K, or 4K) in memory to track pending IO operations.
在内存中，超块为管理活动的(已挂载)文件系统提供必要的信息和状态。
In memory, the superblock provides the necessary information and state to manage the active (mounted) file system.
最后，安装更多内存让文件系统可以把文件和元数据缓存在内存中。
Finally, having extra memory on hand allows the file systems to cache files and metadata in memory.
为了创建一个内存映射赋值，您需要在定义您想要使用的布局的文件系统上选择文件。
To create a memory map rendering, you need to select the file on the file system that defines the layout you want to use.
请记住，在操作系统启动过程中，这些文件系统以及内核最初是存储在内存中的。
Keep in mind that these file systems as well as the kernel are stored in RAM initially during the operating system boot process.
比如，我们可以检查所有运行的进程和他们的内存印象图，我们可以检查CPU信息，挂载文件系统，更多。
For instance, we can check all the running processes and their memory maps, we can check CPU information, mounts, and more.
当经过修改的永久存储分页需要换出(从内存移动到磁盘)的时候，会将它写入到文件系统中。
When a modified permanent storage page needs to be paged out (moved from memory to disk), it is written to a file system.
注意，dentry对象仅存在文件系统内存中，而不能储存在磁盘上。
Note that the dentry objects exist only in file system memory and are not stored on disk.
系统负载可以通过特定的状态值如systemUsage查出，另外还有一些更熟悉的测量，如cpu、内存以及文件系统利用率。
System load can be gauged by a special status value known as system Usage, in addition to more familiar measurements such as CPU, memory, and file system utilization.
msync()：用来让共享内存段与文件系统同步 —当把文件映射到内存时，这种技术有用。
msync(): Used to synchronize a shared memory segment with the file system—a technique useful when mapping a file into memory.
