Free Linux Tutorials

In this tutorial, we will be cloning PC desktop machines using an opensource tool called “G4U”.

g4u (“ghosting for unix”) is a NetBSD-based bootfloppy/CD-ROM that allows easy cloning of PC harddisks to deploy a common setup on a number of PCs using FTP. The floppy/CD offers two functions. more details on –>   http://www.feyrer.de/g4u/

These are the steps on adding additional hard drives on a pre-installed Linux server.

Drives will be detected and can be checked thru the “dmesg” command.

[root@localhost ~]#fdisk /dev/cciss/c0d1

press n to create partition, just use the default settings for it
press w to write exit

3.    Create ext3 filesystem

[root@localhost ~]# mkfs.ext3 /dev/cciss/c0d1p1

4.    Mount that drive to test but first create a directory where to mount it.

[root@localhost ~]#mkdir /data
[root@localhost ~]#mount -t auto /dev/cciss/c0d1p1 /data

This is the list of commonly used commands in systems administration.
