Xen Cluster Management With Ganeti On Debian Lenny
Author: Falko Timme •
Tags: debian, high-availability, virtualization, xen •
Comments: 2 Xen Cluster Management With Ganeti On Debian Lenny Ganeti is a cluster virtualization management system based on Xen. In this tutorial I will explain how to create one virtual Xen machine (called an instance) on a cluster of two physical nodes, and how to manage and failover this instance between the two physical nodes.

Setting Up An Active/Active Samba CTDB Cluster Using GFS & DRBD (CentOS 5.5)

Comments: 2 Setting Up An Active/Active Samba CTDB Cluster Using GFS & DRBD (CentOS 5.5) This article explains how to set up an Active/Active Samba CTDB Cluster, using GFS and DRBD. Prepared by Rafael Marangoni, from BRLink Servidor Linux Team. We use two nodes, both are active nodes, and the requests are loadbalanced. To replicate data between the nodes we use DRBD. To active/active cluster, we must use a ClusterFS (in this case GFS), to make the two nodes to write on the DRBD resource at same time.

How To Set Up An Active/Passive PostgreSQL Cluster With Pacemaker, Corosync, And DRBD (CentOS 5.5)

Comments: 8 How To Set Up An Active/Passive PostgreSQL Cluster With Pacemaker, Corosync, And DRBD (CentOS 5.5) This article explains how to set up (and monitor) an Active/Passive PostgreSQL Cluster, using Pacemaker with Corosync and DRBD. We use two nodes, one active (that answers requests from apps) and the other on passive mode. If the active server is down, the passive one will automatically take its position (being the active node). We are using the CentOS 5.5 (64bits) distribution, but it will probably work on Fedora (and Red Hat, for sure) as well.

Installing A Web, Email And MySQL Database Cluster (Mirror) On Debian 5.0 With ISPConfig 3

Comments: 24 Installing A Web, Email And MySQL Database Cluster (Mirror) On Debian 5.0 With ISPConfig 3 This tutorial describes the installation of a clustered Web, Email, Database and DNS server to be used for redundancy, high availability and load balancing on Debian 5 with the ISPConfig 3 control panel. GlusterFS will be used to mirror the data between the servers and ISPConfig for mirroring the configuration files. I will use a setup of two servers here for demonstration purposes but the setup can scale to a higher number of servers with only minor modifications in the GlusterFS configuration files.

High-Availability Storage With GlusterFS On Ubuntu 10.04 - Automatic File Replication (Mirror) Across Two Storage Servers
Author: Falko Timme •
Tags: high-availability, storage, ubuntu •
Comments: 3 High-Availability Storage With GlusterFS On Ubuntu 10.04 - Automatic File Replication (Mirror) Across Two Storage Servers This tutorial shows how to set up a high-availability storage with two storage servers (Ubuntu 10.04) that use GlusterFS. Each storage server will be a mirror of the other storage server, and files will be replicated automatically across both storage servers. The client system (Ubuntu 10.04 as well) will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86_64 servers with SATA-II RAID and Infiniband HBA.

Sample Configuration of DRBD On CentOS 4.5
Author: babarsaleem • Tags: centos, high-availability, storage • Comments: 4Sample Configuration of DRBD On CentOS 4.5 DRBD is an abbreviation of Distributed Replicated Block Device. DRBD is a block device which is designed to build high-availability clusters. This is done by mirroring a whole block device via (a dedicated) network. You could see it as a network RAID1.

Setting Up A Highly Available NFS Server
Author: Falko Timme • Tags: other, debian, high-availability, storage • Comments: 21Setting Up A Highly Available NFS Server 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.

Tags: backup, debian, high-availability, other, storage •
Comments: 10 DRBD 8.3 Third Node Replication With Debian Etch The recent release of DRBD 8.3 now includes The Third Node feature as a freely available component. This document will cover the basics of setting up a third node on a standard Debian Etch installation. At the end of this tutorial you will have a DRBD device that can be utilized as a SAN, an iSCSI target, a file server, or a database server.
