Ubuntu Servers :: How To Install LessFS (Deduplication FS) On 9.10
Jan 25, 2010LessFS is a relatively new FS. The primary goal for LessFS is an on-disk backup & archiving filesystem.Features of LessFS:
- On-line Deduplication
- On-line Compression
LessFS creates a growable file that represents the LessFS filesystem.My configuration is as follows: 5 Harddisks of varying sizes, concatenated to one disk, using LVM2. The data partition formatted as ext4, with large file option set. I've installed LessFS as follows:
Open a Terminal on your server. Get the prerequisites:
Code:
sudo apt-get install build-essential libselinux1-dev libsepol1-dev pkg-configlibtokyocabinet-dev checkinstall
Get Fuse 2.8.1: download from [URL] the packages called libfuse, libfuse-dev and fuse-utils. Download the ones that correspond to your architecture.Install them like this:
Code:
sudo dpkg -i *.deb
assuming the FUSE files are in the same folder as the shell is.Download & Extract LessFS: Download .tar.gz package from [URL]. Extract like
Code:
tar xzf *.tar.gz
Other Option, All-in one (Note: check for the newest version number at [URL]):
Code:
wget -O- http://sourceforge.net/projects/lessfs/files/lessfs/lessfs-1.0.1/lessfs- .0.1.tar.gz/download | tar xz
cd into lessfs folder and run
Code:
./configure
This gives a lot of text. Check for errors. Run
Code:
make && sudo checkinstall
I didn't test checkinstall, so if it fails, replace "checkinstall" with "make install".
You are done installing. Now configuring:
LessFS isn't made natively on Debian/Ubuntu. That is to see in the startup scipt. I tweaked it a bit, but I must say it's a quick-and-dirty hack. The tweaked script is provided as an attachment (lessfs.sh). Download it and save it to /etc/init.d Edit the file if you want to change the mountpoint to something other than /data. Then do:
Code:
sudo update-rc.d lessfs.sh enable
This creates the correct startup scripts. This isn't nessecary. You can always hand-start lessfs.
The next part is important though:
From the lessfs source folder copy the etc/lessfs.cfg file. Copy it to /etc Then edit the new /etc/lessfs.cfg change the file paths to your liking (tip: Do the data folder 'dta' as the only one on your large partition. For performance reason) Alter the cache settings in a way that it fits your memory. After saving the file, create the mta, dta subfolders at the places you stated above. Also create the mount point folder.
do the following to create the folder:
Code:
sudo mklessfs -c /etc/lessfs.cfg
And you're done Start Lessfs with:
Code:
sudo invoke-rc.d lessfs.sh start
or restart.
Happy Less-ing
General :: How Can GPL Be Approved By OSI As Opensource
Mar 3, 2011According to the Open Source Initiative an open source license must among all other things be "9. License Must Not Restrict Other Software: The license must not place restrictions on other software that is distributed along with the licensed software. For example, the license must not insist that all other programs distributed on the same medium must be open-source software." Now GPL v2 (and all oher versions) instead require "You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. ", basically this is the reason why GPL is considered a viral license: because any works derived from a copyleft work must themselves be copyleft when distributed (and thus they exhibit a viral phenomenon). Now the problem is in wikipedia [URL] I see that GPL is approved by OSI as open source, but the point 9 of OSI and the vitality of GPL should be incompatible with each other!

Jun 2, 2011I think I've one of the badest configurations to use fc15 and gnome-shell. I run a AMD HD 6950 and I have these bugs in gnome-shell (e.g. rainbow color, corrupt icons, ..) with the official AMD fglrx driver.As I can see, the opensource ATI driver only supports cayman based gpu (like mine) if using a 2.6.39 kernel. Mine is a 2.6.38.6-27.fc15.x86_64, so I don't get any support.Any ideas how to get the opensource driver to work and fix these ugly gnome-shell bugs?Shell I install the 2.6.39 Kernel from FC16?I really like the new gnome-shell and got used to it on my thinkpad x61s, so I like to use it on my workstation, too.

May 2, 2011I have problems with ATI Drivers for my graphics HD4850. Opensource drivers work, but often lag mouse and other applications. Then I've installed Additional drivers, which are include in Ubuntu. It's good with mouse and other, but sometimes lag applications and moving windows. In CCSM I disabled Vsync and set refresh rate, but it's still lag on applications, moving windows is OK. What can I do now?
Is ATI Driver version from Additional drivers same as 11.4 from official AMD's webpage? If I will install drivers version 11.4 from AMD's page, will work good?
OR
How can I solve problems with opensource drivers with mouse and applications lag?

View 3 Replies View RelatedUbuntu Multimedia :: XOrg (Opensource) Drivers For ATI Radeon Cards?
Jan 4, 2010 For those of us who were stung last year by ATI's decision to drop support for <= R500 series cards from their closed source, or proprietary driver (known as the FGLRX driver), we are now forced to use the opensource ATI XORG driver. This is not as bad as it sounds, as in doing so, ATI has released a lot of the hardware specs on these older cards and the opensource driver has improved dramatically in the last year as a result.
Ubuntu includes both the ATI and the FGLRX driver install capacities in recent releases (since Intrepid(?)). If one can install the FGLRX driver, you should be able to do this by choosing System>Administration>Hardware Drivers and choosing to activate the ATI drivers; or you can manually install them using this guide: [URL]
However, if you have a card that is or below the R500 series (i.e. not R600+) DO NOT install the FGLRX drivers - you will break your X server (video display). If you don't know what series chipset you have, try the following:
Code:
$ lspci
00:00.0 Host bridge: Intel Corporation Mobile PM965/GM965/GL960 Memory Controller Hub (rev 0c)
00:01.0 PCI bridge: Intel Corporation Mobile PM965/GM965/GL960 PCI Express Root Port (rev 0c)
[Code]....
If you're like me and need a production machine, but just want updated drivers, try this link: [URL]
To add the PPA (Guide): [URL]
These are fairly easy to remove (as described on the site); just remove the PPA from your Software Sources and downgrade the drivers.

Oct 16, 2009my Fedora 11 system is not starting anylonger. It stops with the message:
Code:
VFS: Can't find ext4 filesystem on dev dm-0
The system told me since a while, that a lot of the sectors of one disk of the (software) RAID compound are failed already. So tried to disconnect each of the disks and start them separately. Unfortunaltly this is not working (for one its is not working at all, the other wents the same far as with both), when I tried to recover the system with the Fedora DVD, it said no distribution found. I am quite new and do not know so much about linux system, so i do not know what further information you could need. Maybe it can be important, that both disks are encryped (the system wents so far, that I can type in the password).

Code: Select allDisk is OK, 418 bad sectors (28° C / 82° F)
I did a bit of reading and it seems that most people suggest using badblocks to first get a list of badblocks from the drive and save it to a file. Then use e2fsck to then mark the blocks listed in the badblocks file as bad on the hard drive. My problem here is that this drive is part of a RAID5 array that hosts my OS. I wanted to confirm if this was still the correct process.I boot to my Live Debian disk, stop the raid array if it's active. Then run badblocks + e2fsck commands on the drive in question and then reboot.
Ubuntu Installation :: 9.10 - Non-system Disk Or Disk Error With Manual Partitions
Apr 9, 2010This is the third 9.10 install to do this on two different laptops, so wondering what's up...
In both cases, the goal was to leave a large chunk of unpartitioned disk after the Ubuntu partitions, for a second OS install or a filesystem Ubuntu cannot create like NTFS.
When I install with manual partitions, the system can't boot and asks for me to insert a system disk and press any key. When I reinstall telling Ubuntu to "use the entire disk" it then works.
First laptop, first try:
Remainder of the 500GB disk is free space.
Fails to boot, "insert system disk".
First laptop, second try without the /boot partition:
Remainder of the 500GB disk is free space.
Fails to boot, "insert system disk".
"use entire disk" works perfectly.
Second laptop, first try:
Same thing, non-system disk or disk error, insert system disk.
Second try "use entire disk" is currently in progress but I expect the same to happen.

Jun 28, 2010I have an SiI hardware SATA RAID card, with two 500GB disks in mirrored RAID configuration. When I first plugged them in and set it up, things seemed to work ok, but on boot the raid controller told me that the RAID needed rebuilding, and it would happen automatically after POST. So I didn't worry about it, and the drive mounted fine, and it's been that way for years. I just went in and manually on-line rebuilt the RAID in the controller's BIOS, and now when I boot into Ubuntu, both disks show up in fdisk, but neither show up in /dev/disk/by-uuid. Am I missing something?
