...ook 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 kernel. This is on centos 6.3. 1. download all lustre rpms from whamcloud 2. install kernel, kernel-firmware, kernel-headers, and kernel-devel * in this case, it''s the rpm files with "2.6.32-279.14.1.el6_lustre.x86_64" in their name 3. reboot into this lustre kernel 4. install the remaining rpms 5. download ofed from mellanox "MLNX_O...

System setup: Client: Dual socket Sandy Bridge, with 32GB ram and infiniband connection to lustre server.

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

...ried mounting the Lustre partitions with -o nobarrier (yes, I know it''s dangerous, but I''d really need to speed things up) but I don''t know if that does anything at all.

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 the filesystem internally to some other part of the filesystem. It might be useful t...

Hello All, I have installed and configured Lustre 1.8.4 on SuSe 11.0 and everything works fine if i run modprobe lustre and when the lustre module is getting loaded. But when the server reboots it is not getting loaded. Kindly help. Lnet is configured in /etc/modprobe.conf.local as below. options lnet networks=tcp0(eth0) accept=all For loading lustre module i tried including lustre module in

Hi - I'm searching for file system corruption tool, say it inject disk-errors like multiply owned blocks etc. Later an integrity scan process (like e2fsck) will verify on-disk layout and fix these errors. I'd like to read/understand such tools before writing one for an proprietary on-disk file system. Do we have such tools for ext{2,3,4}fs ? Thanks for any help or pointers! -- ----
