similar to: compiling tests/Embedding

Hello! This is my first post here. I came across the very same problem. It can be reproduced within modified tests/Embedding/RParseEval.c Actually this example has another issue, namely it doesn't wrap everything in R_ToplevelExec . This is a major show stopper for newcomers as that function is barely mentioned anywhere and longjmp into terminated setuploop function followed by R_suicide

Hi, I am working at a major financial institution and we would like to embed R in one of our front office application. The application is written in C/C++ so I started by trying to compile the examples in "tests/Embedding" of R 2.0.1. I have modified "tests/Embedding/Makefile" according https://stat.ethz.ch/pipermail/r-help/2005-February/064341.html and set

I installed 1 MDS , 2 OSS/OST and 2 Lustre Client.

Hi; One of our OSTs filled up. Once we realized this, we executed lctl --device 9 deactivate on our fs''s combo MDS/MGS machine. We saw in the syslog that the OST in question was deactivated: Lustre: setting import ufhpc-OST0008_UUID INACTIVE by administrator request However, ''lfs df'' on the clients does not show that the OST is deactivated there, unless we *also*

Hello, We have running lustre 1.8.1 and have met "No space lest on device" error when uploading 500 Gb small files (less then 100 Kb each). The problem seems to depends on the number of files. If we remove one file, we can create one new file, even with Gb size; but if we haven''t remove something we can''t create even very little file, as an example using touch

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

i'd like to use the C interface to R in a program i'm writing. as a starting point, i'm trying to create a very simple C program that uses R. i've read the R documentation on this, but i'm having trouble figuring out where SEXP is defined and how to use it. i noticed someone else on this list also tried to use the C interface, but they ran into similar problems:

Hi Guys, I''m trying to figure out a way to get a list of files with objects present on an OST that is down. Normally one could do: lfs find -O <OST> dir but that is giving us Input/output errors (I assume because the OST is down). Is there a good way to get a list of objects (Maybe from the MDS?), what OSTs they are on, and correlate them with files? Thanks, Mark -- Mark

Hi everyone, I have seen this question here before, but without a very satisfactory answer. One of our half a dozen clients has lost access to a set of OSTs: > lfs osts OBDS:: 0: lustre-OST0000_UUID ACTIVE 1: lustre-OST0001_UUID ACTIVE 2: lustre-OST0002_UUID INACTIVE 3: lustre-OST0003_UUID INACTIVE 4: lustre-OST0004_UUID INACTIVE 5: lustre-OST0005_UUID ACTIVE 6: lustre-OST0006_UUID ACTIVE

I''m evaluating lustre. I''m trying what I think is a basic/simple ethernet config. with MDT and OST on the same node. Can someone tell me if the following (~150 second recovery occurring when small 190 GB OST is re-mounted) is expected behavior or if I''m missing something? I thought I would send this and continue with the eval while awaiting a response. I''m using

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 all, we use SLES 11 and Lustre 1.8.1.1 + patches and like convert a lustre FS using external journals to one with async journals enabled. Question is whether the procedure: umount <filesystem> on all clients umount <osts> on all OSSes e2fsck <ost-device> on all OSSes for all all OSTs tune2fs -O ^has_journal <ost-device> on all

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

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

if i have a single oss with multiple ost''s do i get any parallelism when striping across the ost''s? i.e. would a client form multiple connections on whatever transport between the itself the oss?

We are seeing some disturbing (probably due to our ignorance) behavior from lustre 1.6.3 right now. We have 8 OSSs with 3 OSTs per OSS (24 physical LUNs). We just created a brand new lustre file system across this configuration using the default mkfs.lustre formatting options. We have this file system mounted across 400 clients. At the moment, we have 63 IOzone threads running
