  • High-Availability Storage With GlusterFS On Ubuntu 10.04 - Automatic File Replication (Mirror) Across Two Storage Servers

    ubuntu Author: falkoTags: , , 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: babarsaleemTags: , , Comments: 4

    Sample 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: falkoTags: , , , Comments: 1

    Setting 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.

  • DRBD 8.3 Third Node Replication With Debian Etch

    debian Author: bhellmanTags: , , , , Comments: 9

    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.

  • Using iSCSI On Debian Lenny (Initiator And Target)

    debian Author: falkoTags: , , , Comments: 6

    Using iSCSI On Debian Lenny (Initiator And Target) This guide explains how you can set up an iSCSI target and an iSCSI initiator (client), both running Debian Lenny. The iSCSI protocol is a storage area network (SAN) protocol which allows iSCSI initiators to use storage devices on the (remote) iSCSI target using normal ethernet cabling. To the iSCSI initiator, the remote storage looks like a normal, locally-attached hard drive.

  • High-Availability Storage Cluster With GlusterFS On Ubuntu

    ubuntu Author: marchostTags: , , Comments: 9

    High-Availability Storage Cluster With GlusterFS On Ubuntu In this tutorial I will show you how to install GlusterFS in a scalable way to create a storage cluster, starting with 2 servers on Ubuntu 8.04 LTS server. Files will be replicated and splitted accross all servers which is some sort of RAID 10 (raid 1 with < 4 servers). With 4 servers that have each 100GB hard drive, total storage will be 200GB and if one server fails, the data will still be intact and files on the failed server will be replicated on another working server. 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 server with SATA-II RAID and Infiniband HBA.

  • Distributed Replicated Storage Across Four Storage Nodes With GlusterFS On Debian Lenny

    debian Author: falkoTags: , , Comments: 0

    This tutorial shows how to combine four single storage servers (running Debian Lenny) to a distributed replicated storage with GlusterFS. Nodes 1 and 2 (replication1) as well as 3 and 4 (replication2) will mirror each other, and replication1 and replication2 will be combined to one larger storage server (distribution). Basically, this is RAID10 over network. If you lose one server from replication1 and one from replication2, the distributed volume continues to work. The client system (Debian Lenny 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.
