similar to: build and install lustre from source code -- warning on livcfs.ko for no modversions

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 Can someone help me figure out a way to compile a 2.4 kernel in a 2.6 system. Basically it keeps failing because it needs the genksyms package, which is provided in the modutils package from redhat, but obviously this isn''t presetn on the 2.6 kernel. I was wondering how the xen maintainers go about compiling their 2.4 kernel and 2.6 kernel. Do you do it on different systems then

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

I'm going to bugz this if no one tells me I made another brain-damaged error here. Also, if I can get one confirmation, it'll let me breath easier. I ran a version searching for ".cmd" and ".c" just trying to convince myself I'm not *that* brain-damaged. You'd think after all these years that regex compilation would be pretty darn stable... Oh! Forgot it was

Hello guys, does anyone of you have problems with chown and chmod operations taking extremely long time to complete. For example chown on 200 MB folder is taking minutes. The MDS is not loaded at all. All other operations (file read and write) seem to be doing fine. Any help is greatly appreciated. _______________________________________________ Lustre-discuss mailing 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

Hi, I tried to compile lustre-client 2.0.0.1 on RHEL4 with kernel 2.6.9-89.0.28.EL-x86_64 and I got 3 errors and 1 warning during the compile. The compile is executed with -Werror option, and it fails in all 4 cases * Error: lustre_compat25.h CC [M] /usr/src/redhat/BUILD/lustre-2.0.0.1/lustre/fid/fid_handler.o In file included from

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 All, I try to use our cluster though samba share. Everything work fine, but I think, we should have -o flock at lustre mount time. Great, it''s work.

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

Hi, I have 2 questions regarding building and installing Lustre server on Ubuntu. We have a running Lustre setup on RHEL and now trying to build and install on Ubuntu. 1. Whether latest Lustre (2.6+) server can be built on Ubuntu with the same steps as for RHEL? Or are there different steps for Ubuntu. 2. Has anyone tried this before and/or Whether Lustre2.6.x
