similar to: Kernel oops when running bonnie++ on btrfs

Hi folks, For people who might be interested, here is how btrfs performs with two partitions on a single SSD drive in a RAID-1 mirror. This is on a Dell E4200 with Core 2 Duo U9300 (1.2GHz), 2GB RAM and a Samsung SSD (128GB Thin uSATA SSD). Version 1.03c ------Sequential Output------ --Sequential Input- --Random- -Per Chr- --Block-- -Rewrite- -Per Chr- --Block--

Hello everyone, Btrfs v0.14 is now available for download. Please note the disk format has changed, and it is not compatible with older versions of Btrfs. For downloads and documention, please see the Btrfs project page: http://btrfs.wiki.kernel.org The oss.oracle.com Btrfs project page will soon start redirecting here. v0.14 has a few performance fixes and closes some races that could have

I've had the chance to use a testsystem here and couldn't resist running a few benchmark programs on them: bonnie++, tiobench, dbench and a few generic ones (cp/rm/tar/etc...) on ext{234}, btrfs, jfs, ufs, xfs, zfs. All with standard mkfs/mount options and +noatime for all of them. Here are the results, no graphs - sorry: http://nerdbynature.de/benchmarks/v40z/2009-12-22/ Reiserfs

I have installed Ubuntu Intrepid Server on bare metal and successfully ran:- # apt-get install ubuntu-xen-server.     It installed several packages on system . Now i can see files /boot/xen-3.3.gz, /etc/init.d/xend, /etc/init.d/xendomains, but no xenified kernel gets in. Attempt  to use vmlinuz-2.6.27-7-server, obviously , fails with system panic.    I do remember recompiling  procedure for Xen

Greetings I've searched to no avail so far... there is bound to be something more intelligible out there...??? I am playing with bonnie++ for the first time... May I please get some advise and list experience on using this or other disk subsystem benchmark programs properly with or without a GUI ? Test system in this case is a Compaq DL360 with 2 to 4 Gig DRAM and qty (2) 36Gig 10k drives

Dear List, I'm not an expert on Linux but I have been using Ubuntu and R sice two years ago. I've just installed Ubuntu Intrepid Ibex (8.10, Kernel: 2.6.27-7-generic) from the scratch and then installed R, following the instruction given on: http://cran.r-project.org/bin/linux/ubuntu/README, and everything worked fine. However, after the installation I realized that the installed

I have recently formatted my system in order to install Intrepid Ibex, and I am now using it with Wine 1.1.7. I did a backup of the prefixes of the games I was using in Hardy / Wine up to 1.1.5, and imported them in my new installment. The games work normally, but the sound is crackling all the time for each of them; something which was not happening in my former installment. I have not noticed

Hello, I am getting a GPG error with the ubuntu repository at the bristol UK mirror. When my source.list has this line: deb http://www.stats.bris.ac.uk/R/bin/linux/ubuntu/ intrepid/ On an "apt-get update" you get this: W: GPG error: http://www.stats.bris.ac.uk intrepid/ Release: The following signatures were invalid: BADSIG D67FC6EAE2A11821 Vincent Goulet <vincent.goulet at

Hello, I have recently installed Ubuntu (8.10) Intrepid Ibex and I am trying to get R version 2.8. I have changed my /etc/apt/sources.list file to include a mirror. I have also added the Vincent Goulet key. However, whenever I run sudo apt-get update sudo apt-get install r-base it installs version 2.71. Given that I am new to Ubuntu, is there anything that I need to do to make ubuntu get

Hi, we''re using Xen 3.3.0 on Debian Etch with 2.6.18.8 kernel from xen.org on dom0. We have problems starting Intrepid domU (using Intrepid''s kernel 2.6.27-7-server) if we give more than 4GB of memory to this domain. Using memory = ''4096'' works perfectly, but changing it to ''4097'' already gives an error. Can anyone put some light on this?

Hello togheter, I've installed R with this instruction: http://edtechdev.blogspot.com/2009/03/r-in-ubuntu-intrepid.html After that I tried to install odfWeave with this: > install.packages("odfWeave") Then there came this warning: Warnung in install.packages("odfWeave") : Argument 'lib' missing: use '/home/johannes/R/i486-pc-linux-gnu-library/2.8'

I noticed a huge problem with the free space cache that was presenting as an early ENOSPC. Turns out when writing the free space cache out I forgot to take into account pinned extents and more importantly clusters. This would result in us leaking free space everytime we unmounted the filesystem and remounted it. I fix this by making sure to check and see if the current block group has a cluster

Hi, I am trying to install R on Ubuntu 8.10. I have added this line: deb http://cran.at.r-project.org/bin/linux/ubuntu intrepid/ in my /etc/apt/sources.list file.

Hi Dirk! It would be great if you could upload a (Debian) package "r-cran-matrix" that includes the latest version of the R package "Matrix" to http://cran.r-project.org/bin/linux/ubuntu/intrepid/ "r-recommended" depends on "r-cran-matrix", but only the (outdated) version that shipped with intrepid (0.999375-10-1) is currently available. Note:

I''ve used the Slicehost Intrepid instructions (http:// articles.slicehost.com/ubuntu-intrepid) to install a new Ubuntu server with Ruby, Rails and passenger. Everything seems to be working OK, save for one thing: my application only service up the files that are in its public folder. The Passenger gem is installed. I''ve done this whole process before without any problem. Any

Having done a current checkout, creating a new FS and running iozone [1] on it results in an oops [2]. remove_suid is called, accessing offset 14 of a NULL pointer.

Hi, I need to install Rmagick to get re-sizing working with Paperclip. My dev machine is on Mac OSX Leopard and the server is on Ubuntu Intrepid 8.1 I dint have Macports or wget at first.

A brief rundown of my experiences with Samba4 <http://wiki.samba.org/index.php/Samba4> on Ubuntu Intrepid: http://ropeonfire.blogspot.com/2008/10/samba4-on-ubuntu-intrepid.html One note in particular that might be helpful to developers: I could join a linux machine running winbind 2:3.2.3-1ubuntu3 to the domain only when running in single process mode. I'm still holding out hope
