This is helpful on production environments that requires a common folder on multiple servers. NFS shares provide quick and efficient file/folder sharing between systems. It’s easy to configure and setup. It’s not compatible on windows machines though- you can Samba protocol for this. This tutorial is done on CentOS but will also work on Ubuntu and other Linux OS.

Manage Drives and Disk Partitions using fdisk
One of the common administrative tasks under UNIX/Linux is to add a new disk to the system to increase its storage capacity. This tutorial will walk through on adding disk to a running system, making a partition, assigning file system and creating mount point for the new disk. The fdisk utility is very helpful especially when adding new drives to be used for Logical Volume Management (LVM).

Logical Volume Management (LVM) Tutorial
What is LVM?
Logical Volume Management or LVM allow the server to utilize multiple hard drives and combine them to single storage. It allows an easy way to extend or shrink partition depending on how the user needs.
LVM also supports snapshots and cloning for easy backup of system images. LVM is used to allocating disks, striping, mirroring and resizing logical volumes. This tutorial will walk you through using LVM to manage disk partitions and filesystem sizes.

Setup NPTD Server and client for CENTOS 6
Network Time Protocol is used to synchronize the time on Linux Server. NTP continuously sync and adjusts the time setting of the client by querying the NTP server. It is recommended to be used by systems which need very fine tuned time synchronization requirements (milliseconds). Recommended setup to use is to have a common NTPD server on your LAN and then configure other devices to sync to it.
