Distributed Storage Across Four Storage Nodes With GlusterFS 3.2.x On Ubuntu 12.10
Author: Falko Timme •
Tags: storage, ubuntu •
Comments: 1 This tutorial shows how to combine four single storage servers (running Ubuntu 12.10) to one large storage server (distributed storage) with GlusterFS. The client system (Ubuntu 12.10 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.

Monitoring Linux And Unix Server Temperatures With Opsview
Author: Opsview • Tags: monitoring • Comments: 0Monitoring Linux And Unix Server Temperatures With Opsview Managing power consumption in a Datacenter is a key factor in helping keep overall business energy costs down and ensuring servers are running at optimum performance. Overheating can lead to increased costs for cooling and also runs the risk of servers crashing. Opsview server monitoring software can be used to check and alert on server temperature and also the temperature of individual components within a server (Memory, CPU and Hard drives). Thresholds and alerts can be set for when critical temperatures are exceeded, helping to keep hot-running servers in check. This blog post details how to configure Opsview to monitor the temperature of Linux and Unix servers.

Installing And Using OpenVZ On Scientific Linux 6.3
Author: Falko Timme • Tags: linux, openvz, virtualization • Comments: 0Installing And Using OpenVZ On Scientific Linux 6.3 In this HowTo I will describe how to prepare a Scientific Linux 6.3 server for OpenVZ. With OpenVZ you can create multiple Virtual Private Servers (VPS) on the same hardware, similar to Xen and the Linux Vserver project. OpenVZ is the open-source branch of Virtuozzo, a commercial virtualization solution used by many providers that offer virtual servers. The OpenVZ kernel patch is licensed under the GPL license, and the user-level tools are under the QPL license.

Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Fedora 18 x86_64)
Author: Falko Timme •
Tags: antivirus, email, fedora, postfix •
Comments: 9 This document describes how to install a Postfix mail server that is based on virtual users and domains, i.e. users and domains that are in a MySQL database. I'll also demonstrate the installation and configuration of Courier (Courier-POP3, Courier-IMAP), so that Courier can authenticate against the same MySQL database Postfix uses. The resulting Postfix server is capable of SMTP-AUTH and TLS and quota. Passwords are stored in encrypted form in the database. In addition to that, this tutorial covers the installation of Amavisd, SpamAssassin and ClamAV so that emails will be scanned for spam and viruses. I will also show how to install SquirrelMail as a webmail interface so that users can read and send emails and change their passwords.

Distributed Replicated Storage Across Four Storage Nodes With GlusterFS 3.2.x On Ubuntu 12.10
Author: Falko Timme •
Tags: high-availability, storage, ubuntu •
Comments: 0 This tutorial shows how to combine four single storage servers (running Ubuntu 12.10) 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 (Ubuntu 12.10 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.
