In hopes of improving the quality, coverage, and currency of the Lustre User Manual, I''m putting out a call to the Lustre community for contributors to this important resource. The user manual is especially important for new users to Lustre, but has fallen into some disrepair now that there is no longer a dedicated documentation writer for it. As well, there are many sections of the

Hello, I am having trouble installing the server modules for lustre 2.1.4 and use mellanox''s OFED distribution so we may use infiniband. Would you folks look at my procedure and results below and let me know what you think? Thanks very much! The mellanox ofed installation builds and installs some kernel modules too, so I used this method to ensure OFED compiled against the correct

Whamcloud and EMC are jointly investigating how to be able to contribute the Lustre client code into the upstream Linux kernel. As a prerequisite to this, EMC is working to clean up the Lustre client code to better match the kernel coding style, and one of the anticipated major obstacles to upstream kernel submission is the heavy use of code abstraction via libcfs for portability to other

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

Hi, We run four-node Lustre 2.3, and I needed to both change hardware under MGS/MDS and reassign an OSS ip. Just the same, I added a brand new 10GE network to the system, which was the reason for MDS hardware change. I ran tunefs.lustre --writeconf as per chapter 14.4 in Lustre Manual, and everything mounts fine. Log regeneration apparently works, since it seems to do something, but

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:

Hello, in preparation for CentOS 6.5 I was trying to build Lustre 1.8 client on CentOS 6.4 updated with 2.6.32-431 kernel. Seems like recent changes in fs.h (/usr/src/kernels/2.6.32-431.el6.x86_64/include/linux/fs.h) is causing problems. make[5]: Entering directory `/usr/src/kernels/2.6.32-431.el6.x86_64'' cc1: warnings being treated as errors

Hi all, I used the method described below to build client rpms with the source kit lustre-1.8.5.tar.gz. There was only one error reported during the make rpms, relating to lustre-iolit-1.2-root, but the rpms were built under /usr/src/packages/RPMS/x86_64. The rpms lustre-modules, lustre and lustre-tests were then installed smoothly without any complaints. But the subsequent "modprobe

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

We have a script that adds corruption to ext2/3/4 filesystems and runs e2fsck on it. It definitely could be improved, but it still catches some occasional errors: http://git.whamcloud.com/?p=tools/e2fsprogs.git;a=commit;h=aee44c669bebe29bfdb8a1c86da443234f8bc257 It tries to format the filesystem with different features and options, then adds corruption from both random data and copying parts of
