Managing Filesystems : fstab

Post date: April 15, 2005, 23:04 Category: System Views: 6605 Comments
Tutorial quote: Understanding how the BSD filesystem manages disk space is critical to successfully managing a BSD server or workstation. However, this topic is generally overlooked since it is rarely used outside of installation and upgrades. It is also a very simple topic and most people assume you understand how it all works.

This article gives a quick synopsis on filesystem layout and tries to briefly explain how to understand /etc/fstab. The fstab(5) man pages, while good, do little to teach the basics to new sysadmins.

Filesystems (ext3, reiser, xfs, jfs) comparison on Debian Etch

Post date: April 23, 2006, 08:04 Category: Benchmarks Views: 5801 Comments
Tutorial quote: There are a lot of Linux filesystems comparisons available but most of them are anecdotal, based on artificial tasks or completed under older kernels.

Benchmarking Maildir Delivery on Linux Filesystems

Post date: April 12, 2005, 07:04 Category: Benchmarks Views: 3026 Comments
Tutorial quote: The goal of this set of benchmarks is to determine which of the leading Linux filesystems (ext2, ext3, ReiserFS, and XFS) offer the best performance when used for accepting maildir deliveries. The resulting system should be a good balance of delivery and retrieval performance under potentially high concurrent filesystem load.

Filesystem Encryption Tools for Linux

Post date: May 28, 2007, 00:05 Category: System Views: 3429 Comments
Tutorial quote: Crypto filesystems keep your data safe – even if someone steals your computer.Linux offers a number of encrypted filesystem options – each with a different approach to the encryption problem.Encrypted filesystems may be overkill
for family photos or your résumé, but they make sense for network-accessible servers that hold sensitive business
documents, databases that contain credit-card information, offline backups, and laptops.

rsnapshot - Local/Remote Filesystem backups utility in openSUSE

Post date: October 6, 2008, 21:10 Category: System Views: 3838 Comments
Tutorial quote: rsnapshot is a filesystem backup utility based on rsync. Using rsnapshot, it is possible to take snapshots of your filesystems at different points in time. Using hard links, rsnapshot creates the illusion of multiple full backups, while only taking up the space of one full backup plus differences. When coupled with ssh, it is possible to take snapshots of remote filesystems as well.

Managing OpenVZ With The Vtonf Control Panel On CentOS 5.2

Post date: December 2, 2008, 15:12 Category: Miscellaneous Views: 4934 Comments
Tutorial quote: Vtonf is a free web-based control panel (released under the GPL license) for managing virtual private servers (VPS) based on OpenVZ. It makes it very easy to create and manage OpenVZ VMs even for people with little technical knowledge. Right now, Vtonf is available only for RedHat, Fedora, and CentOS (support for Debian is planned), therefore I describe its installation and usage on a CentOS 5.2 server.
