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:

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

Greetings Community! Today we are very excited to announce that Xyratex has purchased Lustre? and its assets from Oracle. We intend for Lustre to remain an open-source, community-driven file system to be promoted by our community organizations. We undertook the acquisition because we realize its importance to the entire community and we want to help ensure that it will continue to deliver for all

Hi I want my lustre do such things during OST failed: if some file has stripe data on th failed OST, any operation on the file will return IO error without blocking, and also at this moment I can create and read/write new file or read/write files which have no stripe data on the failed OST without blocking. What should I do ? How to configure? thanks! swin -------------- next part

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

This may be in the documentation. If so, I missed it. If a site has multiple Lustre file systems, the documentation implies that there only needs to be a single MGS for an entire site (regardless of the number of file systems). However, I also know it is fairly common to have a combined MGS/MDT. So here are the questions. 1. If we are going to have several Lustre file systems,

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 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

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

Hello list members, I started to develop a kernel module which hooks into Lustre 2.3 for controlling data access based on nid and uid/gid. The background is the following: Here at GSI we have currently a reserved uid/gid space which partner institutes are using to access our exported Lustre mounts. However, we currently have no mechanism to control (guaranty) that the reserved uid/gid space are

We''ve had a really busy year with some great progress around Lustre development in particular! Also some new important participants have joined. Lots

In 1.6.0, when creating a MDT, you could specify multiple --mgsnode options and it would failover between them. 1.6.3 only seems to take the last one and --mgsnode=192.168.1.252 at o2ib:192.168.1.253 at o2ib doesn''t seem to failover to the other node. Any ideas how to get around this? Robert Robert LeBlanc College of Life Sciences Computer Support Brigham Young University leblanc at
