Monitoring and Managing Linux Software RAID

Post date: April 15, 2005, 23:04 Category: System Views: 2713 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.

A Beginner's Guide To LVM

Post date: January 16, 2007, 19:01 Category: System Views: 3844 Comments
Tutorial quote: This guide shows how to work with LVM (Logical Volume Management) on Linux. It also describes how to use LVM together with RAID1 in an extra chapter. As LVM is a rather abstract topic, this article comes with a Debian Etch VMware image that you can download and start, and on that Debian Etch system you can run all the commands I execute here and compare your results with mine. Through this practical approach you should get used to LVM very fast.

Learn REXX fast

Post date: September 1, 2005, 01:09 Category: Programming Views: 3226 Comments
Tutorial quote: If you’ve programmed under IBM operating systems, you’ve undoubtedly heard of Rexx. Rexx is the scripting and command language IBM bundles with all its mainframe, mid-range, and lower-end operating systems. What you might not be aware of is that Rexx also runs on almost every other operating system in the known universe. You can download Rexx free for all versions of Windows┬«, Linux, UNIX┬«, BSD, Mac OS, and DOS, and many other systems. It even runs on the three major operating systems for handheld devices: Windows CE, Palm OS, and Symbian/EPOC32.

What this means is, if you learn Rexx, you’ll know a scripting language that runs everywhere from mainframes to handhelds—and everything in between. Rexx is a general-purpose language that's powerful enough for mainframes yet flexible enough for other platforms. Best of all, Rexx is easy to learn.
