Relevance: 8.00
It's a known fact that although disk storage capacities are improving at an impressive rate, disk performance improvements are occurring at a rather slower rate. Here are the two techniques for measuring disk performance in Linux. With a little bit of torturing, and some fun on the way, find out how fast your hard disk drive really is.

Relevance: 7.29
Ever had to install a second hard disk on a machine running Linux? If it is an IDE hard disk, the jumper settings of the hard disk decide how it is detected by the computer. This article details the experiences of the author in adding a second IDE hard disk in a Linux PC.

Pain-free disk space management with LVM

08/22/2007  
Relevance: 7.06
Managing disk space used to be a royal pain for admins and users. Running out of disk space often meant reinstalling Linux or spending a few hours with tools like Parted to resize partitions. However, using the Logical Volume Manager (LVM) tools, you can grow, shrink, and manage disk space with very little hassle.

How To Resolve Veritas Disk Group Cluster Volume Management Problems On Linux or Unix

09/30/2008  
Relevance: 6.97
How minor device numbers can affect disk sharing within a Veritas Cluster! Today we're going to look at an issue that, while it doesn't happen all that often, happens just enough to make it post-worthy. I've only seen it a few times in my"career," but I don't always have access to the fancy software, so this problem may be more widespread than I've been lead to believe ;) The issue we'll deal with today is: What do you do when disk groups, within a cluster, conflict with one another? Or, more correctly, what do you do when disk groups within a cluster conflict with one another even though all the disk is being shared by every node in the cluster?

Clone your Ubuntu installation onto a new hard disk

11/14/2008  
Relevance: 6.93
Just upgraded your system with a shiny new hard disk and want to make it your new book disk? Cloning Ubuntu to another hard disk is easy. In fact, Ubuntu provides tools to clone the entire hard disk -- including the Windows partition, if there's one on there. This is the kind of fundamental task that Linux excels at, in fact. This article is excerpted from the newly published book Ubuntu Kung Fu and published with the express permission of the publisher, the Pragmatic Programmers, LLC.

EFI and ZFS

03/16/2007  
Relevance: 6.91
I have a 1TB RAID array that has to be moved from my one remaining Solaris machine (which will no longer boot) to a Linux machine. I was expecting that - as with the other disk which has undergone the same process - this would appear as a SunOS usr disk and partition, which I could then mount read-only and dump elsewhere before reformatting the disk as ext3& dumping it back again.

Tips from an RHCE: How can I make dd give me a progress report?

08/17/2007  
Relevance: 6.52
If you've been working with Linux very long, you've probably encountered dd, the deceptively simple utility for copying a stream of data from here to there. You may have used it to zero a disk before letting it leave the building, to benchmark io hardware by writing a certain number of bytes, to put a disk image on a floppy or usb drive, or even to back up an entire disk.

Picture your disk space with 3-D filesystem browsers

11/01/2006  
Relevance: 6.31
You don't need a Ph.D. in scientific visualization to have some fun with three-dimensional data. Whether you're searching for an unused nook in a cramped disk partition, or trying to find the bloated temp/ folder that's crashing your system, sometimes the flat folder view of a traditional GUI file browser is little help. Luckily, Linux offers a variety of 3-D filesystem that can make your disk usage statistics come alive.

7 Uses of GParted Live

08/03/2008  
Relevance: 6.28
I've been using GNU Parted to slice and dice my disk in preference to the fdisk for almost as long as I've been using Linux. We all fill up our hard-drives from time to time, but thanks to Gnome GParted, rearranging disk partitions isn't as terrifying as it used to be. In fact, armed with a GParted Live CD, there's a swathe of disk space fiddling jobs I can tackle without gnawing my fingers to the bone.
