You can convert your existing Ext3 filesystem to Ext4 with an easy procedure.Things to remember
* Unmount the filesystem before convert
* Filesystem must be non-root
This way you can improve the performance, storage limits and features of your existing filesystem without reformatting and/or reinstalling your OS and softwares.
"This is the last post of Firebug tutorial series. I’m going to explain about Net panel, CSS panel and DOM panel in this tutorial. As there are not so much things to say about that, I’m gonna write up about all three panels in one post."
There might be the situation, that your root filesystem runs out of space, so it has to be expanded. With filesystems other than the root filesystem this could easily be done for instance with gparted. With the root filesystem this is not possible, as gparted could only expand filesystems that are not mounted, which is impossible with the root filesystem.
Here's a howto for Debian and Mandriva which explains how to make your desktop look nice if you're using a mix of KDE and GTK+. Because Ubuntu is based on Debian, this howto might also apply to Ubuntu, but I have not verified this.
To change the properties of the panel, which by default is on the bottom edge of the desktop, you need to access the Panel Tool Box widget located on the extreme right edge of the panel. Depending on the distribution you are using, the panel could be locked or unlocked.
This tutorial is based on another howto written by DevilMan, however I didn't like the idea of manually compiling every package or the use of a GUI to get the software installed. This howto will work on a Gutsy Server or Gutsy desktop. With that said some of this howto is a direct copy from the original.
This tutorial will explain you how to boot from a BTRFS filesystem with kernel 2.6.31-RC4 and BTRFS 0.19. BTRFS is a new filesystem with some really interesting features like online defragmenting and snapshots. BTRFS is an experimental filesystem, use at your own risk. The kernel used is also experimental.
The filesystem used in the vast majority of Linux (and to a lesser extent on other Unix) distributions is the ext3 filesystem, which stands for extended filesystem. Slashdot recently pointed to an article on IBM DeveloperWorks discussing the new ext4 filesystem currently in development, and some of its new features. So what is a filesystem really?
