Hello, I have a production script that do read operations to a lot of small files. I read that one can gain performance boost with small files by using a loop device on top of Lustre. So a created 500 GB file striped across all of my OSTs(which are 8). I formatted the file with ext2 fs, and mounted it on a client. Just for the sake of testing a simple bash script finds all files with a given file

Since in Linux we are mostly a debian shop we''d like to stick with debian for our calculation nodes if possible. So I wanted to ask the lustre 2.2 instructions for Debian are they more or less relevant to lustre 2.4/2.5 or am I going headlong into a tall brick wall. Also are newer clients backwards compatible with older server software? I am currently just setting up a demo environment

Hi all, I am a grad student at Carnegie Mellon University. I had my course work in advanced storage systems in previous semester, and I am interested to work on Lustre. I prefer to take up a project that could be completed in a duration of a month or two. Since I am a novice w.r.t. my familiarity with Lustre code base, I seek your opinion to choose a project from the list:

LUG 2013 is being held in San Diego this year, April 15-19. Intel and Aeon Computing are co-sponsoring a Pre-LUG party that first Monday night, Apr 15th. Beer and Lustre, a great combination! We''ll be in the Omni Hotel, the same location as LUG itself, up on the 10th floor, catching up with old Lustre friends and hopefully make some new ones. Please join us! For more information, email

Greetings, I was trying to update the Lustre Wikipedia page today, and while checking the latest release version, I found that the 2.x download links from these pages do not work: http://wiki.lustre.org/index.php/Download:Download http://lists.lustre.org/pipermail/lustre-announce/2010-August/000250.html http://downloads.lustre.org/public/lustre/ http://wiki.lustre.org/index.php/Main_Page I

We have just discovered that a large buffer cache generated from traversing a lustre file system will cause a significant system overhead for applications with high memory demands. We have seen a 50% slowdown or worse for applications. Even High Performance Linpack, that have no file IO whatsoever is affected. The only remedy seems to be to empty the buffer cache from memory by running

Dear colleagues, I was wondering whether anyone may give me some help on a python issue in R. I tried to invoke Python from R, but failed. I have set up a system path to call python: "C:\python27" in path file. In addition, I have confirmed python interpreter properly. The code I used is typical for checking, which is as follows: x <- .Python("listdir", "/tmp",

I built and installed Lustre from source. When I installed built luster-modules- RPM, I got libcfs.ko from the kernel-2.6.18-prep has no modversions (the message is posted below), so it cannot be reused for kernel. Is there any procedure I need to do during the build? There is include/config/modversion.h under patched kernel, but the file does not have any contens and its size is 0. Thanks for

I'm setting up a new CentOS 4.4 server to work with Fruity (a frontend program that operates Nagios). For security purposes, what chmod and chown settings do you put on the /var/www/html folders? Also, can anyone recommend any good LAMP hardening guides? While I'm not planning on putting this into production, I'd like to cover all my bases before that's an issue. --------------

Hi there, I'm pushing a directory tree from a samba server with notificytion via fileschanged (FAM) to a webserver for procession images into an image-database. These files have to be rw by wwwrun on the receiver. If the receiver woul pull the files, the script could chmod after transfer, but how can the sender do a chown/chmod on the receivers side? Maybe -o -g -p can be enhanced or
