It covers creating and mounting btrfs file systems, resizing btrfs file systems online, adding and removing devices, changing RAID levels, creating subvolumes and snapshots, using compression and other things. btrfs is still marked as experimental, but all those features make it a very interesting and flexible file system that should be taken into consideration when you look for the right file system. falko Thu, 29 Nov 2012 10:48:06 GMT http://www.howtoforge.com/automatic-file-replication-mirror-across-two-storage-servers-with-glusterfs-3.2.x-on-ubuntu-12.10 This tutorial shows how to set up a high-availability storage with two storage servers (Ubuntu 12.10) 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 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. falko Tue, 22 Jan 2013 12:26:48 GMT http://www.howtoforge.com/build-your-own-video-community-with-lighttpd-and-flowplayer-ubuntu-9.10 This article shows how you can build your own video community using lighttpd with its mod_flv_streaming module (for streaming .flv videos, the format used by most major video communities such as YouTube) and its mod_secdownload module (for preventing hotlinking of the videos) on Ubuntu 9.10. I will use FlowPlayer as the video player, a free Flash video player with support for lighttpd's mod_flv_streaming module. I will also show how you can encode videos (.mp4 .mov .mpg .3gp .mpeg .wmv .avi) to the FLV format supported by Adobe Flash. falko Tue, 16 Mar 2010 12:59:38 GMT http://www.howtoforge.com/configuring-dnssec-on-bind9-9.7.3-on-debian-squeeze-ubuntu-11.10 This guide explains how you can configure DNSSEC on BIND9 on Debian Squeeze and Ubuntu 11.10. It covers how to enable DNSSEC on authoritative nameservers (master and slave) and on resolving nameservers, creation of keys (KSKs and ZSKs), signing of zones, key rolling with rollerd, zone file checking with donuts, creation of trust anchors, using DLV (DNSSEC look-aside validation), and getting your DS records into the parent's zone. falko Tue, 17 Apr 2012 10:15:23 GMT http://www.howtoforge.com/cpu_frequency_scaling_ubuntu So, you have an irritatingly loud CPU fan which is making you consider whether or not launching your laptop through the nearest window is a good idea. Well, before you do that, why not give CPU frequency scaling a go. falko Mon, 27 Aug 2007 11:58:59 GMT http://www.howtoforge.com/creating-advanced-mysql-based-virtual-hosts-on-lighttpd-ubuntu-12.04 This guide explains how you can create advanced virtual hosts on a lighttpd web server on Ubuntu 12.04 that are stored in a MySQL database. The method described here does not use the lighttpd mod_mysql_vhost module, and unlike mod_mysql_vhost (which allows you to store only the hostname and document root of a vhost in a database), this method allows to store individual configuration directives for each vhost in the MySQL database. falko Sun, 09 Sep 2012 08:47:30 GMT http://www.howtoforge.com/creating-an-nfs-like-standalone-storage-server-with-glusterfs-3.2.x-on-ubuntu-12.10 This tutorial shows how to set up a standalone storage server on Ubuntu 12.10.

Back In Time is a simple backup tool for Linux inspired from "flyback project" and "TimeVault". The backup is done by taking snapshots of a specified set of directories. falko Tue, 25 Aug 2009 11:58:34 GMT
