Monitoring and Managing Linux Software RAID

Post date: April 15, 2005, 23:04 Category: System Views: 2777 Comments
Tutorial quote: Systems administrators managing a data center face numerous challenges to achieve required availability and uptime. Two of the main challenges are shrinking budgets (for hardware, software, and staffing) and short deadlines in which to deliver solutions. The Linux community has developed kernel support for software RAID (Redundant Array of Inexpensive Disks) to help meet those challenges. Software RAID, properly implemented, can eliminate system downtime caused by disk drive errors. The source code to the Linux kernel, the RAID modules, and the raidtools package are available at minimal cost under the GNU Public License. The interface is well documented and comprehensible to a moderately experienced Linux systems administrator.

In this article, I'll provide an overview of the software RAID implementation in the Linux 2.4.X kernel. I will describe the creation and activation of software RAID devices as well as the management of active RAID devices. Finally, I will discuss some procedures for recovering from a failed disk unit.

My First Linux Server, Part 2

Post date: April 14, 2005, 22:04 Category: Miscellaneous Views: 3766 Comments
Tutorial quote: A file server is a specialized PC that holds large numbers of files that many people on a network can access. It "serves up" files to everyone instead of each person having files on his or her own PC. The good news is that you don't have to be a network guru to set up a basic file server. If you followed the Easy Linux Install steps in Part 1, you are ready to set up a Linux PC as a file server.

While there are many ways to set up a network and a server, this article concentrates on the simplest approaches with the highest chance of quick success.

Linux Directory Structure

Post date: December 26, 2007, 15:12 Category: Miscellaneous Views: 4422 Comments
Tutorial quote: The directory structure of Linux/other Unix-like systems is very intimidating for the new user, especially if he/she is migrating from Windows. In Windows, almost all programs install their files (all files) in the directory named: `Program Files.’ Such is not the case in Linux. The directory system categorises all installed files. All configuration files are in /etc, all binary files are in /bin or /usr/bin or /usr/local/bin. Here is the entire directory structure along with what they contain.

Correct Multimedia Support in SUSE Linux 9.2

Post date: April 13, 2005, 01:04 Category: Multimedia Views: 3378 Comments
Tutorial quote: SUSE Linux is one of the better desktop Linux distributions on the market today, providing a functional and aesthetically pleasing environment for the new Linux user as well as seasoned veterans. On thing that puzzles many users is the lack of proper multimedia support in SUSE. The developers have basically crippled it from playing virtually all types of multimedia content that's common on the Internet today. This can be a frustrating dilema for new users, so I have written a short HOWTO to help you get everything in order on your new desktop.

It should be noted that you don't necessarily need to install apt to fix the multimedia problem on SUSE, but it's probably the most beneficial way to get it done. You can easily remove the offending packages and install new ones not provided by SUSE, but by using apt, you'll get the benefit of having a much larger package base available to you... something that SUSE has suffered from for a very long time. With or without apt, let's get things going with this HOWTO.

The Linux /proc Filesystem as a Programmers' Tool

Post date: June 22, 2005, 09:06 Category: Programming Views: 3411 Comments
Tutorial quote: My entry into systems programming was guided by my desire to understand further the operating systems I was working with daily as a contract UNIX and, later, Linux system administrator. The result of this was ifchk, a packet sniffer detector I wrote in C and released in June of 2003. ifchk initially was written under IRIX and then ported to Linux, mostly under the 2.4 kernel. The current ifchk revision, beta 4, recently was released and beta 5 is on the way.

My work on ifchk has allowed me to examine programmatically several areas of operating system functionality. Examples include the Linux netlink(7) and rtnetlink(7) facilities, device control--that is, network interfaces--via ioctl(2), signals and proc, the process filesystem. Proc and its ability to display a wide array of data concerning the runtime state of a system are the focus of our discussion here.

Using Samba on Debian Linux

Post date: February 3, 2006, 01:02 Category: Network Views: 3726 Comments
Tutorial quote: This article will show you how to install Samba 3.X on Debian Linux 3.1 (Sarge) and make it authenticate against a Windows server running Active Directory. It is not intended on replacing the actual official Samba 3 manual - which is a quite good read anyway.

Read - Write support for NTFS partition on OpenSuse 11.x

Post date: January 12, 2009, 08:01 Category: Desktop Views: 3319 Comments
Tutorial quote: The ntfs-3g driver is an open source, GPL licensed, third generation Linux NTFS driver which was implemented by the Linux-NTFS project. It provides full read-write access to NTFS, excluding access to encrypted files, writing compressed files, changing file ownership, access right.

Technically it's based on and a major improvement to the third generation Linux NTFS driver, ntfsmount. The improvements includes functionality, quality and performance enhancements.

Linux Kernel Magic SysRq keys in openSUSE for crash recovery

Post date: September 28, 2008, 17:09 Category: System Views: 3398 Comments
Tutorial quote: The Linux Kernel offers you something that allows you to recover your system from a crash or at the least lets you to perform a proper shutdown using the Magic SysRq Keys. The magic SysRq key is a select key combination in the Linux kernel which allows the user to perform various low level commands regardless of the system’s state using the SysRq key. It is often used to recover from freezes, or to reboot a computer without corrupting the filesystem.

Building a Linux supercomputer using SSH and PVM

Post date: April 11, 2006, 21:04 Category: Network Views: 3210 Comments
Tutorial quote: If you have a couple of old Linux boxes sitting around, then you've got the makings of a supercomputer. Dust them off, install Secure Shell (SSH) and Parallel Virtual Machine (PVM), and start your complex algorithms.
