Setting Up A Highly Available NFS Server

Post date: April 1, 2006, 05:04 Category: Network Views: 6262 Comments
Tutorial quote: In this tutorial I will describe how to set up a highly available NFS server that can be used as storage solution for other high-availability services like, for example, a cluster of web servers that are being loadbalanced. If you have a web server cluster with two or more nodes that serve the same web site(s), than these nodes must access the same pool of data so that every node serves the same data, no matter if the loadbalancer directs the user to node 1 or node n. This can be achieved with an NFS share on an NFS server that all web server nodes (the NFS clients) can access.

As we do not want the NFS server to become another "Single Point of Failure", we have to make it highly available. In fact, in this tutorial I will create two NFS servers that mirror their data to each other in realtime using DRBD and that monitor each other using heartbeat, and if one NFS server fails, the other takes over silently. To the outside (e.g. the web server nodes) these two NFS servers will appear as a single NFS server.

In this setup I will use Debian Sarge (3.1) for the two NFS servers as well as for the NFS client (which represents a node of the web server cluster).

Setting Up An NFS Server And Client On OpenSUSE 11.3

Tune and Tweak NFS for Top Performance

Post date: June 26, 2005, 00:06 Category: Optimizing Views: 3345 Comments
Tutorial quote: As promised in our previous NFS article, we will now explore mount options in a bit more detail. We will also talk about differences between NFS implementations among various UNIX flavors, and the wonderful capability automatic mounting provides.

Encrypted NFS with OpenSSH

Post date: May 21, 2005, 19:05 Category: Network Views: 2774 Comments
Tutorial quote: NFS is a widely deployed, mature, and understood protocol that allows computers to share files over a network. The main problems with NFS are that it relies on the inherently insecure UDP protocol, transactions are not encrypted, hosts and users cannot be easily authenticated, and its difficulty in firewalling. This article provides a solution to most of these problems for Linux clients and servers. These principles may also be applied to any UNIX server with ssh installed. This article assumes basic knowledge of NFS and firewalling for Linux.

Setting Up Network RAID1 With DRBD On Ubuntu 11.10

Post date: November 1, 2011, 09:11 Category: Installing Views: 18741 Comments
Tutorial quote: This tutorial shows how to set up network RAID1 with the help of DRBD on two Ubuntu 11.10 systems. DRBD stands for Distributed Replicated Block Device and allows you to mirror block devices over a network. This is useful for high-availability setups (like a HA NFS server) because if one node fails, all data is still available from the other node.

NFS Server and Client Configuration in Ubuntu

Post date: May 7, 2007, 06:05 Category: Network Views: 6557 Comments
Tutorial quote: NFS was developed at a time when we weren’t able to share our drives like we are able to today - in the Windows environment. It offers the ability to share the hard disk space of a big server with many smaller clients. Again, this is a client/server environment. While this seems like a standard service to offer, it was not always like this. In the past, clients and servers were unable to share their disk space.
