系统上的对象可以是文件、文件系统、卷组、设备等。
Objects on a system could be files, file systems, volume groups, devices, and more.
它们缓存最近使用过的文件系统对象。
更有益的是运用这些知识，这样就可以指定您要访问的文件系统对象。
What's more useful is to use this knowledge so you can specify filesystem objects that you want to access.
其他的对象，比如文件系统的图像或文件的情况与此相同。
The same can be said for other objects, such as images or files from the filesystem.
没有执行权限，目录下的文件系统对象就是不可访问的。
Without execute permission, the filesystem objects inside a directory are not accessible.
如果消息表明成功，来自返回消息的信息将填充到structstat对象，从而使用来自虚拟文件系统的记录数据取代真实的数据。
If the message indicates success, information from the returned message gets stuffed into the struct stat object, replacing the real data with the recorded data from the virtual file system.
Ceph不只是一个文件系统，还是一个有企业级功能的对象存储生态环境。
Ceph is not only a file system but an object storage ecosystem with enterprise-class features.
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.
作为ClearCase的附加产品，ClearCaseMultiSite提供了可靠的存储着所有文件系统对象(无论是二进制的还是文本的)的资料库副本——跨地域。
As an add-on product for ClearCase, ClearCase MultiSite provides reliable replication — across geographies — of repositories storing any file system object, whether binary or textual.
帮助对象包括缓存管理(Cache对象)和用于发现应用程序源文件改变的内部文件系统监控器。
Helper objects include the cache manager (the cache object) and the internal file system monitor used to detect changes in the source files that form the application.
根目录条目(dentry)对象也缓存在这里，因为它是文件系统所在的块设备。
The root directory entry (dentry) object is cached here also, as is the block device on which this file system resides.
Linux以一组通用对象的角度看待所有文件系统。
Linux views all file systems from the perspective of a common set of objects.
要注意的是，Ceph客户，对象存储端点，元数据服务器(根据文件系统的容量)可以有许多，而且至少有一对冗余的监视器。
Note that there can be many Ceph clients, many object storage endpoints, numerous metadata servers (depending on the capacity of the file system), and at least a redundant pair of monitors.
Linux通过一个称为inode (indexnode的缩写)的对象管理文件系统中的所有对象。
Linux manages all objects in a file system through an object called an inode (short for index node).
dentry引用super_block, super_block定义包含该对象的特定文件系统实例。
The dentry refers to the super_block, which defines the particular file system instance in which this object is contained.
从存储角度来看，Ceph对象存储设备执行从对象到块的映射(在客户端的文件系统层中常常执行的任务)。
From a storage perspective, Ceph object storage devices perform the mapping of objects to blocks (a task traditionally done at the file system layer in the client).
Linux文件系统保存文件和其他对象（例如符号链接、类似磁盘的设备和目录），并分组归类到各个目录（其他操作系统称为文件夹）中。
Linux filesystems hold files and other objects (e.g. symbolic links, devices like disks, and directories) grouped into directories (known as folders on other operating systems).
今天，我们发现一种新的日志结构文件系统，并看到一个文件系统被引入到对象存储上。
Today, we find a new log-structured file system and the introduction of a file system over an object store.
文件系统对象的每个唯一的装入实例通过一个虚拟文件系统结构进行表示。
Each unique mount instance of a file system object is represented by a virtual file system structure.
这样一来，就更容易迁移到对象级存储，因为提供的文件系统本身是传统的文件系统。
In this way, it's easier to migrate to object-level storage, because the file system presented is a traditional file system.
当显示用于公共使用时，只需将ZODB对象容器称为“文件夹”，用户将非常愉快地导航对象层次结构，就像是导航熟悉的文件系统一样。
Just call your ZODB object containers "Folders" when displaying them for public consumption, and users will happily navigate your object hierarchy as though it were a familiar filesystem.
您可能知道，UNIX系统为文件系统上的每一个对象记录一个atime，或称为访问时间，每次读取文件时，atime都会被更新。
As you probably know, UNIX systems record an atime, or access time, for each object on the filesystem that gets updated every time a file is read.
仅永久储存文件系统inode,dentry对象的目的是改善性能。
Only file system inodes are stored permanently, where dentry objects are used to improve performance.
文件系统中管理的每个对象(文件或目录)在Linux中表示为一个inode。
Every object that is managed within a file system (file or directory) is represented in Linux as an inode.
WebSpherePortal使用portlet来简单地读取文件，并将它添加到响应对象中以便显示给用户，这样就可以发布文件系统中所有可用的内容。
WebSphere Portal publishes whatever is available on the file system using a portlet to simply read the file and add it to the response object to display for the user.
为了解决这个问题，pam_ns . so可以将它的文件系统标为从属对象，见清单2。
To resolve this, pam_ns.so could mark its filesystem as slave, as shown in Listing 2.
