Is there instructions on how to use the patchless client on RHEL4 ? For version 1.6.2 We would prefer a rpm, but we are not scared of doing a build if needed. Brock Palen Center for Advanced Computing brockp at umich.edu (734)936-1985

on our cluster that has been running lustre for about 1 month. I have 1 MDT/MGS and 1 OSS with 2 OST''s. Our cluster uses all Gige and has about 608 nodes 1854 cores. We have allot of jobs that die, and/or go into high IO wait, strace shows processes stuck in fstat(). The big problem is (i think) I would like some feedback on it that of these 608 nodes 209 of them have in dmesg

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

[Sorry for possible duplicated thread.] Hi. I''m new to Xen and I would know if it works well in a cluster environment (Beowulf, OpenMosix, CoLinux etc). I need an HPC running some virtual machines. Is this possible with Xen? Regards. -- Allysson Steve Mota Lacerda Administrador de Redes http://www.stevelacerda.net _______________________________________________ Xen-users mailing

Should I be seeing messages like: Dec 14 12:06:59 nyx170 kernel: Lustre: MGS: haven''t heard from client dadccfac-8610-06e7-9c02-90e552694947 (at 141.212.30.185 at tcp) in 234 seconds. I think it''s dead, and I am evicting it. when the client was shut down cleanly? and the lustre file system is mounted via /etc/fstab ? The file system (i would hope) would be unmounted

I use gentoo on xen, in the gentoo docs (gentoo compiles everything almost) they have options like ''-march=pentium3'' should i be using the gcc option for the cpu im using (pentium3), I understand that domU''s and even dom0''s speak the "XEN" arch, so could using cpu specific flags like this cause problems? what are other xen+gentoo users using

Hello CFS, I was wondering if the new SLES10 kernel will be part of the 1.6.4 release. It appears to be tracked by: https://bugzilla.lustre.org/show_bug.cgi?id=13874 As this contains a major security fix (privilege escalation), it is a mandatory upgrade in many places and it would be nice to not have to roll our own kernel. Thanks, Kit

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

I am running on CentOS 5 distribution without adding any updates from CentOS. I am using the lustre 1.6.4.1 kernel and software. I have two NICs that run though different switches. I have the lustre options in my modprobe.conf to look like this: options lnet networks=tcp0(eth1,eth0) My MGS seems to be only listening on the first interface however. When I try and ping the 1st interface (eth1)

Hello, I''ve several problems with quota on our testcluster: When I set the quota for a person to a given value (e.g. the values which are provided in the operations manual), I''m able to write exact the amount which is set with setquota. But when I delete the files(file) I''m not able to use this space again. Here is what I''ve done in detail: lfs checkquota

Hello! Hey didnt a setting for the 10 second network timeout get into the 2.6.20 kernel? if so how do we set this? I am getting OCFS2 1.3.3 (2201,0):o2net_connect_expired:1547 ERROR: no connection established with node 1 after 10.0 seconds, giving up and returning errors.

Hi! Is there a way to view ext3 filesystem's maintained journal (in a human-readable-format)? I ask, because i have had a server crash before and now i'm wondering if i might take a look at last things that my server did straight before crash. I guess clarifying log insertions might be lost before buffers were flushed to disk. Thx.

Hi, Lustre manual 1.6 v18 says that that in production lustre debug level should be set to fairly low. Manual also says that I can verify that level by running following commands: # sysctl portals.debug This gives ne following error error: ''portals.debug'' is an unknown key cat /proc/sys/lnet/debug gives output: ioctl neterror warning error emerg ha config console cat

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,

I am one of the hosts of Research Computing and Engineering (www.rce-cast.com). We host shows on HPC related topics and we have had listener requests for a show on Gluster. Would one or two Gluster devs be willing to take an hour for a phone/skype interview to inform users about Gluster and its unique features? If you have any questions please let me know.
