第1章 Terminologies

Terminologies美 [.t?rm?'nɑl?d?i]术语；术语学；名词学

1.1 Access Control Lists

Access Control Lists (ACLs) allows you to assign different permissions for different users or groups even though they do not correspond to the original owner or the owning group.

访问列表(ACLs)允许你指定为不同的用户和组分配不同的权限，即使它们不

对应于原始所有者或所属的组。

correspond美 [.k?r?'spɑnd]v.通信；符合；相当于；相一致

1.2 Brick

Brick is the basic unit of storage, represented by an export directory on a server in the trusted storage pool.Brick美 [br?k] n.砖；砖块；积木；可靠的朋友v. and adj.

Brick是存储的基本单元，表现为服务器上可信存储池的导出目录。

建议您不要将系统的根分区用于存储后端

1.3 Cluster

A cluster is a group of linked computers, working together closely thus in many respects forming a single computer.

集群是一组彼此互联的计算机组，紧密协同工作表现的就像就像单台计算机一样。

1.4 Distributed File System

Extended file attributes (abbreviated xattr) is a filesystem feature that enables users/programs to associate files/dirs with metadata.

扩展属性是文件系统的一个特性，允许用户或应用为文件和目录关联更多的元数据信息。

1.6 FUSE

Filesystem in Userspace (FUSE) is a loadable kernel module for Unix-like computer operating systems that lets non-privileged users create their own file systems without editing kernel code. This is achieved by running file system code in user space while the FUSE module provides only a \to the actual kernel interfaces.

在用户空间的文件系统(FUSE)是一个用于类Unix操作系统的可加载的内核模块以允许非特权用户在不适用内核代码的情况下创建自己的文件系统，实现了在用户空间运行文件系统代码，FUSE模式实际上仅仅对内核接口提供了一个桥接。

1.7 GFID

Each file/directory on a GlusterFS volume has a unique 128-bit number associated with it called the GFID. This is analogous to inode in a regular filesystem.

每个GlusterFS中的文件或目录都有一个128bit的数字标识，称为GFID。

1.8 glusterd

Gluster management daemon that needs to run on all servers in the trusted storage pool.

Gluster管理守护进程需要运行在所有的提供受信存储池的服务器上。

1.9 Geo-Replication

Geo-replication provides a continuous, asynchronous, and incremental replication service from site to another over Local Area Networks (LANs), Wide Area Network (WANs), and across the Internet.
