如果在物理卷上已经建立的逻辑卷，则将逻辑卷移动到其他物理卷上执行vgreduce命令，从卷组中删除物理卷。如：
vgreduce /dev/vgnn /dev/disk/disk4
卷组的导入/导出

导出卷组：从系统中删除卷组的信息，但卷组的结构信息仍保留在物理卷上关闭卷组，如：

将逻辑卷的镜像数减少到0：
lvreduce -m 0 /dev/vg00/lvol1

删除指定物理卷上的镜像：
lvreduce -m 0 /dev/vg00/lvol1 /dev/disk/disk4
逻辑卷的扩展与缩小

逻辑卷的查看：lvdisplay 将逻辑卷扩展到320M：
lvextend –L 320 /dev/vg01/lvo11

查看物理卷的信息：
pvdisplay -v /dev/disk/disk3
卷组的创建

创建卷组中的group文件：
mkdir /dev/vgname mknod /dev/vgname/group c major 0xminor

自2008 年 3 月发行的 HP-UX 11i v3 起， group文件将自动创建

操作系统试题及答案

操作系统试题及答案一、选择题1、以下哪个选项不是操作系统的功能？A.进程管理B.内存管理C.安全管理D.病毒防护答案：D.病毒防护。

病毒防护不是操作系统的基本功能，而是由单独的防病毒软件提供的。

2、下列哪个不是进程的概念？A.程序的执行实例B.一个正在执行的程序C.一个正在运行的程序D.一个执行中的程序片段答案：D.一个执行中的程序片段。

进程是指一个正在执行的程序，它包括程序的代码、数据和系统资源（如内存、文件、设备等）。

3、在分页系统中，页面的大小由哪个因素决定？A.物理内存的大小B.操作系统的类型C.程序的大小和类型D.虚拟内存的大小答案：C.程序的大小和类型。

在分页系统中，页面的大小通常由程序的大小和类型决定。

4、下列哪个选项不是文件系统的特点？A.可重用性高B.易于维护和升级C.数据安全性高D.数据可共享性强答案：C.数据安全性高。

文件系统的数据安全性并不一定高，它依赖于特定的安全措施和权限管理。

例如，一些文件系统可能没有访问控制列表（ACL）或其他安全机制。

二、简答题5、请简述操作系统的基本功能。

答案：操作系统的基本功能包括进程管理、内存管理、文件管理和设备管理。

进程管理负责创建、调度和终止进程；内存管理负责分配、保护和回收内存；文件管理负责创建、读取、写入和删除文件；设备管理负责控制和管理各种输入/输出设备。

51、请简述分页系统和分段系统的区别。

答案：分页系统和分段系统都是用于实现虚拟内存的技术，但它们在组织和分配内存空间的方式上有所不同。

分页系统将内存空间分为固定大小的页面，而分段系统将内存空间分为不同大小的段。

分段系统可以更好地满足不同程序的需求，因为每个段可以具有不同的属性（如访问权限、大小等）。

操作系统复习试题及答案一、选择题1、以下哪个选项不是操作系统的功能？A.进程管理B.内存管理C.文件系统管理D.数据库系统管理答案：D解释：操作系统主要负责计算机系统的资源管理，包括进程管理、内存管理、文件系统管理和设备管理等。

The drd command has five major modes of operation:cloneClones a booted system to an inactive system image. The drdclone mode copies the LVM volume group or VxVM disk groupcontaining the volume on which the root file system ("/") ismounted.mountMounts all file systems in an inactive system image. Themount point of the root file system is either/var/opt/drd/mnts/sysimage_000 or/var/opt/drd/mnts/sysimage_001. If the inactive systemimage was created by the most recent drd clone command, themount point of the root file system is/var/opt/drd/mnts/sysimage_001. If the inactive systemimage was the booted system when the most recent drd clonecommand was run, the mount point of the root file system is/var/opt/drd/mnts/sysimage_000.umountUnmounts all file systems in the inactive system imagepreviously mounted by a drd mount command.runcmdRuns a command on an inactive system image. Only a selectgroup of commands may be run by the runcmd mode. These arecommands which have been verified to have no affect on the- 1 - Formatted: October 17, 2011drd(1M) drd(1M)booted system when executed by drd runcmd. Such commandsare referred to as DRD-Safe. The commands kctune,swinstall, swjob, swlist, swmodify, swremove, swverify, andview are currently certified DRD-Safe. An attempt toexecute any other command will result in a runcmd error. Inaddition, not every software package may safely be processedby sw* commands. The DRD-Safe SW-DIST commands are aware ofrunning in a DRD session and will reject any unsafepackages.

试卷答案
一. 单项选择题
二. 判断题
三. 问答题
第一题：
后台作业将命令行的控制权交给用户，显示提示符可以继续执行其它命令；前台作业独占控制台，在命令结束前不会交回命令提示符
第二题
级别0：关机状态。

当系统进入该级别，停止所有进程，并将系统恢复到关机状态
级别s：单用户运行级别，用于执行系统管理相关任务，只有一个物理控制台可以使用；
级别S：与单用户级别相似，唯一区别是可以从作为系统控制台的终端登陆
级别1：启动一些基本的系统进程，并启动文件系统，但还是单用户模式
级别2：多用户运行级；多数系统守护进程和服务已经启动；
级别3：网络服务启动，NFS文件系统已经导出，启动CDE图形环境；
级别4：为使用老式的HP VUE图形环境用户启用图形用户接口；
级别5，6：对用户定义的服务有效；
可以使用init命令改变运行级别，如:init 3。

注意不能使用init S从较高运行级别进入单用户模式，可以使用shutdown命令将系统改变到单用户模式。

第三题
一个物理卷代表一个磁盘；一个逻辑卷由一个或者多个物理卷构成；所有的物理卷的数据存储容量组合起来构成卷组的容量；逻辑卷在一个卷组中创建并可以跨越多个物理卷。
