Hi, I''m seeing what can only be described as dismal striped write performance from lustre 1.6.3 clients :-/ 1.6.2 and 1.6.1 clients are fine. 1.6.4rc3 clients (from cvs a couple of days ago) are also terrible. the below shows that the OS (centos4.5/5) or fabric (gigE/IB) or lustre version on the servers doesn''t matter - the problem is with the 1.6.3 and 1.6.4rc3 client kernels

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

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

All, I''ve added a new 2.2 TB OST to my cluster easily enough, but this new disk array is meant to replace several smaller OSTs that I used to have of which were only 120 GB, 500 GB, and 700 GB. Adding an OST is easy, but how do I REMOVE the small OSTs that I no longer want to be part of my cluster? Is there a command to tell luster to move all the file stripes off one of the nodes?

Hi, We run four-node Lustre 2.3, and I needed to both change hardware under MGS/MDS and reassign an OSS ip. Just the same, I added a brand new 10GE network to the system, which was the reason for MDS hardware change. I ran tunefs.lustre --writeconf as per chapter 14.4 in Lustre Manual, and everything mounts fine. Log regeneration apparently works, since it seems to do something, but

Hi all, after installing a Lustre test file system consisting of 34 OSTs, I encountered a strange error when trying to set up quotas: lfs quotacheck gave me an "Input/Output error", while in /var/log/kern.log I found a Lustre error LustreError: 20807:0:(quota_check.c:227:lov_quota_check()) lov idx 32 inactive Indeed, in /proc/fs/lustre/lov/.../target_obd all 34 OSTs were listed

Chris, Perhaps you need to perform some write_conf like command. I''m not sure if this is needed in 1.6 or not.

Hi, Our lustre environment is: 2.6.9-55.0.9.EL_lustre.1.6.3smp I would like to change recovery timeout from default value 250s to something longer I tried example from manual: set_timeout <secs> Sets the timeout (obd_timeout) for a server to wait before failing recovery. We performed that experiment on our test lustre installation with one OST. storage02 is our OSS [root at

Hi, I am trying to compile the R-dev version on a unix Suse machine and got errors.

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.

I want to config one 50T OST stroage, is it okay? Since I know that the limitation of ext3 is 1XT. Thnaks

Hello Guys, I am looking to extend/create a file system that span networks/device of any kind, shape and manner :) Check out http://www.insync.za.net/openufs/ (also on http://openufs.sourceforge.net - but Iam not here to adv. the site !) I would like to know, where can I find what EXT3 will write to the disk, how it works etc. Surely EXT3 will write something like this : Block 0 - (1024 bytes)

I'm setting up a new file server and I just can't seem to get the expected performance from ext3. Unfortunately I'm stuck with ext3 due to my use of Lustre. So I'm hoping you dear readers will send me some tips for increasing ext3 performance. The system is using an Areca hardware raid controller with 5 7200RPM SATA disks. The RAID controller has 128MB of cache and the disks

Hi, thanks for previous help. I have some question about Lustre RPC and the sequence of events that occur during large concurrent write() involving many processes and large data size per process. I understand there is a mechanism of flow control by credits, but I''m a little unclear on how it works in general after reading the "networking & io protocol" white paper. Is

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

OK, so our old MDS had hardware issues so I configured a new MGS / MDS on a VM (this is a backup lustre filesystem and I wanted to separate the MGS / MDS from OSS of the previous), and then did this: For example: mount -t ldiskfs /dev/old /mnt/ost_old mount -t ldiskfs /dev/new /mnt/ost_new rsync -aSv /mnt/ost_old/ /mnt/ost_new # note trailing slash on ost_old/ If you are unable to connect both
