There are three Disk Partitions /dev/hda8, /dev/hda9, /dev/hda10 having size 100MB of each partition. Create a Logical Volume named testvolume1 and testvolume2 having a size 250MB. Mount each Logical Volume on lvmtest1, lvmtest2 directory.
Answer and Explanation:
Steps of Creating LVM:
1.pvcreate /dev/hda8 /dev/hda9 /dev/hda10
pvdisplay command is used to display the information of physical volume.
2.vgceate test0 /dev/hda8 /dev/hda9 /dev/hda10
vgdisplay command is used to display the information of Volume Group.
3.lvcreate –L 250M –n testvolume1 test0
lvdisplay command is used to display the information of Logical Volume.
4.lvcreate –L 250M –n testvolume2 test0
5.mkfs –t ext3 /dev/test0/testvolume1
6.mkfs –t ext3 /dev/test0/testvolume2
7.mkdir /lvtest1
8.mkdir /lvtest2
9.mount /dev/test0/testvolume1 /lvtest1
10.mount /dev/test0/testvolume2 /lvtest2
11.vi /etc/fstab
/dev/test0/testvolume2/lvtest2ext3defaults0 0
/dev/test0/testvolume1/lvtest1ext3defaults0 0
To create the LVM( Logical Volume Manager) we required the disks having ‘8e’ Linux LVM type. First we should create the physical Volume, then we can create the Volume group from disks belongs to physical Volume. lvcreate command is used to create the logical volume on volume group. We can specify the size of logical volume with –L option and name with -n option.

Install the Redhat Linux RHEL 5 through NFS. Where your Server is server1.example.com having IP 172.24.254.254 and shared /var/ftp/pub. The size of the partitions are listed below:
/1048
/home1028
/boot 512
/var 1028
/usr2048
Swap->1.5 of RAM Size
/archiveconfigure the RAID Level 0 of remaining all free space.
After completing the installation through NFS solve the following questions. There are two networks 172.24.0.0/16 and 172.25.0.0/16. As well as there are two domains example.com on 172.24.0.0/16 network and my133t.org on 172.25.0.0/16 network. Your system is based on example.com domain. SELinux must be in enforcing mode.
Answer and Explanation:
1. Insert the CD on CD-ROM and start the system.
2. In Boot: Prompt type linux askmethod
3. It will display the language, keyboard selection.
4. It will ask you for the installation method.
5. Select the NFS Image from the list
6. It will ask the IP Address, Net mask, Gateway and Name Server. Select Use
Dynamic IP Configuration: because DHCP Server will be configured in your exam lab.
7. It will ask for the NFS Server Name and Redhat Enterprise Linux Directory.
Specify the NFS Server: 172.24.254.254
Directory: /var/ftp/pub
8. After Connecting to the NFS Server Installation start in GUI. Go up to the partition screen by selecting the different Options.
9. Create the partition According to the Question because Size and what-what partition should you create at installation time is specified in your question
10.Create the two RAID partitions having equal size of remaining all free space.
11.Click on RAID button
12.Type mount point /archive
13.Select RAID Level 0
14.Click on ok
15. Then select the MBR Options, time zone and go upto package selections.
It is another Most Important Time of installation. Due to the time limit, you should care about the installation packages. At Exam time you these packages are enough.
X-Window System
GNOME Desktop
(these two packages are generally not required)
Administration Tools.
System Tools
Windows File Server
FTP Servers
Mail Servers
Web Servers
Network Servers
Editors
Text Based Internet
Server Configuration Tools
Printing Supports
When installation will complete, your system will reboot. Jump for another Question.
Change the Group Owner of /data to training group.
Answer and Explanation:
chown or chgrp command is used to change the ownership.
Syntax of chown: chown [-R] username:groupname file/directory
Syntax of chgrp: chgrp [-R] groupname file/directory
Whenever user creates the file or directory, the owner of that file/directory automatically will be that user and that user’s primary group name.
To change group owner ship
chgrp training /data Which set the Group Ownership to training
or
chown root.training /data Which set the user owner to root and group owner to training group.
Verify /data using: ls -ld /data
You will get: drwxr-xr-x 2 root training …………..
/data Directory is shared from the server1.example.com server. Mount the shared directory that:
when user try to access, automatically should mount
when user doesn’t use mounted directory should unmount automatically after 50 seconds.
Shared directory should mount on/mnt/dataon your machine.
Answer and Explanation:
vi /etc/auto.master
/mnt/etc/auto.misc--timeout=50
vi /etc/auto.misc
data-rw,soft,intrserver1.example.com:/data
service autofs restart
chkconfig autofs on
When you mount the other filesystem, you should unmount the mounted filesystem, Automount feature of linux helps to mount at access time and after certain seconds, when user unaccess the mounted directory, automatically unmount the filesystem.
/etc/auto.master is the master configuration file for autofs service. When you start the service, it reads the mount point as defined in /etc/auto.master.
Make user1, user2 and user3 belongs to training group.
Answer and Explanation:
usermod -G training user1
usermod -G training user2
usermod -G training user3
Verify from : cat /etc/group
There are two types of group, I) primary group II) Secondary or supplementary group.
Primary Group: Primary group defines the files/directories and process owner group there can be only one primary group of one user.
Secondary Group is used for permission. Where permission are defined for group members, user can access by belonging to that group.
Here user1, user2 and user3 belong as supplementary to training group. So these users get the permission of group member.
Create the group named sysusers.
Answer and Explanation:
1.groupadd sysusers
groupadd command is used to create the group and all group information is stored in /etc/group file.
Set the Hostname station?.example.com where ? is your Host IP Address.
Answer and Explanation:
hostname station?.example.comThis will set the host name only for current session. To set hostname permanently.
vi /etc/sysconfig/network
HOSTNAME=station?.example.com
service network restart
Create one partitions having size 100MB and mount it on /data.
Answer and Explanation:
Use fdisk /dev/hdaTo create new partition.
Type nFor New partitions
It will ask for Logical or Primary Partitions. Press l for logical.
It will ask for the Starting Cylinder: Use the Default by pressing Enter Key.
Type the Size: +100MYou can Specify either Last cylinder of Size here.
Press P to verify the partitions lists and remember the partitions name.
Press w to write on partitions table.
Either Reboot or use partprobe command.
Use mkfs –t ext3 /dev/hda?
Or
mke2fs –j /dev/hda? To create ext3 filesystem.
vi /etc/fstab
Write:
/dev/hda?/dataext3defaults1 2
11. Verify by mounting on current Sessions also:
mount /dev/hda? /data
