Testing the new file system in Ubuntu


Btrfs is a new file system supported by Linux, which focuses incorporate more advanced features, fault tolerance and repair. In this article we will see which are the main features Btrfs file system, how to use it on Ubuntu 10.10 and finally a series of performance tests to see how it behaves.

   Once installed we test the support Btrfs with:
10. $ dmesg
    

Create a btrfs filesystem

If you have not created a partition type during installation Btrfs can do it later. For the tests I will use

/ dev/sda7
• , use any free partition to have:
  
$ sudo mkfs-t btrfs / dev/sda7

Btrfs Btrfs v0.19 We can also convert partition type directly ext3/ext4 Btrfs directly without lose the data contained in the order (again I do tests with partition / dev/sda7 ): $ sudo

btrfs-convert / dev/sda7

Use the tools to manage partitions btrfs
local Btrfs List partitions: $ sudo

btrfs-show

  Analyze Btrfs file system (with the partition removed): sudo

btrfsck / dev / sda7





tests For testing I have prepared 3 partitions: a type ext4, reiserfs type one and type btrfs 10Gb each. On each of them I have run tests that evaluate the speed of creating and deleting files, copying a large file and multiple small files, compression and decompression of data.

The results are: (all results in seconds except for the first test)

Maverick is the codename for the future Ubuntu 10.10 if all goes well will be released in October this year. From which we can test the Alpha1



still do not know exactly what will be the novelty of this version and its features. That is why I decided from here to start a wish list with the 10 features I'd like found in Maverick also'll bring the desires I have been gathering in

Twitter and IRC (I must say that I share some of these views, but I still it seems that all must be heard)

• also encourage all readers to leave their own wishes and opinions as comments. When you exit the final version of Ubuntu 10.10 will see if it really has fulfilled the wishes of their users or not.

My desk at Maverick Alpha1

• My wishes for Ubuntu 10.10

(numbered in italics my desires and wishes of other users)

A graphical tool to configure all grub2. Grub2 with default wallpaper. Support
Btrfs file system in the installer.
synchronization tool with Android phones. support the latest graphics technologies such as GPGPU.



sound system standardized and simplified.

KDE based desktop. Greater control over the drivers (proprietary and free) installed on your system. Best

phone holder Phones in general. Longer

of hardware support.
• Increased support for ATi graphics (proprietary driver). Empathy with webcam support on all accounts, especially MSN.
  New default theme.

1. integrated multimedia converter totem or as a standalone application.
   Restore default gimp. Change
by gthumb F-Spot as default image viewer
.
2. ccsm installed by default.
   Installation with "Expert Mode" to define grub2 options, choose packages ...


3. ubuntuone Improvements: export contacts, user preferences, photo albums ...
   Navitas Steam and games.

4. 
   history and frequent operations in nautilus (Zeitgeist extension). Continue the development of social desktop, editor blogs, feed reader ... Delete Evolution of the default installation.

6. Updated
   I add the wishes left as comments in the post (most interesting): Change Nautilus Nautilus Elementary.


7. 
   
   
8. 
   Remove Gwibber that although I liked a lot, she is too heavy (especially for netbooks).
Tomboy by Gnote
Change (without Tomboy and F-Spot, Mono libraries are expendable as well.)


10. -indicator that the applet is able to check mail accounts POP or IMAP. Go

For holders of a graph
ATi addition to the free driver , we have the option to install the proprietary driver fglrx

• . The main advantage of this driver is a better performance in 3D operations. Note: its main drawback is the restrictive policy on ATi hardware support "old." Only the newer models are supported, for that reason I could not use it on my first system and the content of this article is not directly tested by me.
driver installation and activation of

We will install the driver from the repositories, it is the most neuve, but the reasons for using this method is that the process will be much easier and hardware support is higher.
will install the driver with: sudo aptitude install

Intel using free driver. The advantage of this driver is that is fitted as standard in Ubuntu and is free, its main disadvantage is the low performance achieved which makes it difficult or impossible to play games that require a high level graphic.
For this article I used 10.04 Lucid Lynx 32bit Ubuntu on a Asus EeePC 1005HA Netbook with Intel Mobile 945GME Express graphics

driver installation and activation of

This is the driver that is used by default after installation which generally will not need to install it, but if it has been cleared for any reason we can reinstall and use it with the command: sudo aptitude reinstall
xserver-xorg-video-intel & & sudo dpkg-reconfigure xserver-xorg Check results The fastest way to verify that the drivers have been installed and in use is using the command:

glxinfo Mesa. And we are able to configure stationery, put those 3D screensavers that impressive or use gnome-shell

• .

Desktop Effects (compiz) with free driver Intel

Gnome-shell

The bad news for most gamers is that the driver hardly able to move with ease any 3D game.
