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

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

I''m a Lustre newbie who just joined this list. I''d appreciate any help on the following Lustre 2.4 issue I''m running into: Every time I mount the MDT, the mount appears to succeed but /var/log/messages contains the message: "LustreError: 11-0: lustre-MDT0000-lwp-MDT0000: Communicating with 0@lo, operation mds_connect failed with -11". The MDT uses 4 local

Can anyone point me to a study or anything from some site that has a story re monitoring/tracking Lustre for: * Basic health (to catch problems before users call) * Performance régressions due to software, hardware, etc. * Bad actors from the user community. Are there simple probes of Lustre health? * Are there metrics available from internal Lustre monitoring? * Even

It seems that lustre puts its modules in /lib/modules/2.6.16.21-0.8-default despite the fact that my kernel is 2.6.16.21-0.8-smp ! uname -a Linux n32 2.6.16.21-0.8-smp #4 SMP Sun Sep 24 08:47:30 BST 2006 i686 i686 i386 GNU/Linux make[3]: Nothing to be done for `install-exec-am''. /bin/sh ../../mkinstalldirs /lib/modules/2.6.16.21-0.8-default/kernel/fs/lustre /usr/bin/install -c -m 644

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

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

Dear Lustre Community, After researching a number of distributed file systems for deployment in a production environment with the main purpose of performing both batch and real-time distributed computing I''ve identified Lustre as a potential solution. The key properties that our system should exhibit: - an open source, liberally licensed, yet production ready, e.g. a mature, *

Hi all, Here is the situation: I have 2 nodes MDS1 , MDS2 (10.0.0.22 , 10.0.0.23) I wish to use as failover MGS, active/active MDT with zfs. I have a jbod shelf with 12 disks, seen by both nodes as das (the shelf has 2 sas ports, connected to a sas hba on each node), and I am using lustre 2.4 on centos 6.4 x64 I have created 3 zfs pools: 1. mgs: # zpool

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

Dear, everyone We have stuck with the problem that the OSS connect one dead client or one with changed IP address all the time until we reboot the dead client. From the OSS log message, we can get the information as follows: Jul 7 14:45:07 com01 kernel: Lustre: 12180:0:(socklnd_cb.cLustre: 12180:0:(socklnd_cb.c:915:ksocknal_launch_packet()) No usable routes to 12345-202.Lustre:

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 Guys, I had a situation yesterday where I had a 10Gbe adapter on my lustre client configured but not active (the cable was plugged in and had link but the port was down) and this actually brought down our cisco switch. This is a new port that I am setting up. The reason why the switch went down was due to the amount of broadcast traffic coming from this port even though it was shutdown:

Hello, We had a problem with our disk controller that required a reboot. 2 of our OSTs remounted and went through the recovery window but clients hang trying to access them. Also /proc/fs/lustre/obdfilter/$UUID/ is empty for that OST UUID.

Hi I used lustre-1.8.3 for Centos5.4. I patched the kernel according to Lustre 1.8 operations manual.pdf. I have a problem when I want to implement quota. My cluster configuration is: 1. one MGS/MDS host (with two devices: sda and sdb,respectively) with the following commands: 1) mkfs.lustre --mgs /dev/sda 2) mount -t lustre /dev/sda /mnt/mgt 3) mkfs.lustre --fsname=lustre
