One NIS Domain named rhce.com is configured in your lab, server is 192.168.0.254. rhce100, rhce200,rhce300 user are created on domain server. Make your system as a member of rhce.com domain. Make sure that when nis user login in your system home directory should get by them. Home directory is separately shared on server eg /home/stationx/ where x is you station number.
A. 1. Use the authconfig --nisserver=<NIS SERVER> --nisdomain=<NIS DOMAIN> -- update Example: authconfig --nisserver=192.168.0.254 -nisdomain=rhce.com --update
or system-config-authentication
Click on Enable NIS
Type the NIS Domain: rhce.com
Type Server 192.168.0.254 then click on next and ok
You will get a ok message.
vi /etc/auto.master and write at the end of file /home/stationx /etc/auto.home --timeout=60
vi /etc/auto.home and write * -rw,soft,intr 192.168.0.254:/home/stationx/& Note: please specify your station number in the place of x.
Service autofs restart
Login as the rhce1 or rhce2 or rhce3 on another terminal will be Success. According to QUESTION, rhce.com domain is already configured. We have to make a client of rhce.com domain and automatically mount the home directory on every client. To make a member of domain, we use the autheconfig with options or system-configauthentication command. There a are lots of authentication server i.e NIS, LDAB, SMB etc. NIS is a RPC related Services, no need to configure the DNS, we should specify the NIS server address. Here Automount feature is available. When user tried to login, home directory will automatically mount. The automount service reads the configuration from /etc/auto.master file. On /etc/auto.master file we specified the mount point the configuration file for mount point.
B. 1. Use the authconfig --nisserver=<NIS SERVER> --nisdomain=<NIS DOMAIN> -- update Example: authconfig --nisserver=192.168.0.254 -nisdomain=rhce.com --update
or system-config-authentication
Click on Enable NIS
Type the NIS Domain: rhce.com
Type Server 192.167.0.253 then click on next and ok
You will get a ok message.

A. The LVM system organizes hard disks into Logical Volume (LV) groups. Essentially, physical hard disk partitions (or possibly RAID arrays) are set up in a bunch of equalsized chunks known as Physical Extents (PE). As there are several other concepts associated with the LVM system, let's start with some basic definitions:
* Physical Volume (PV) is the standard partition that you add to the LVM mix.
Normally, a physical volume is a standard primary or logical partition. It can also be a RAID array.
* Physical Extent (PE) is a chunk of disk space. Every PV is divided into a number
of equal sized PEs. Every PE in a LV group is the same size. Different LV groups can have different sized PEs.
Logical Extent (LE) is also a chunk of disk space. Every LE is mapped to a specific PE .
Logical Volume (LV) is composed of a group of LEs. You can mount a filesystem such as /home and /var on an LV.
Volume Group (VG) is composed of a group of LVs. It is the organizational group for LVM. Most of the commands that you'll use apply to a specific VG.
Verify the size of Logical Volume: lvdisplay /dev/vg0/lv1
Verify the Size on mounted directory: df -h or df -h mounted directory name
Use : lvextend -L+400M /dev/vg0/lv1
ext2online -d /dev/vg0/lv1 to bring extended size online.
Again Verify using lvdisplay and df -h command.
