lustre osd implementation
hello,
does lustre support OSD T10 standard? Can it be used with IBM''s/Intel''s OSD
initiator and target?
Thanks,
Ashish

OSTs inactive on one client (only)
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

Balancing I/O Load
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

Why does lmList() fail when lm() doesn't?
Dear r-helpers,
Can anyone suggest why lm() doesn't complain here:
summary(osss.lm1 <- lm(logOdds ~ c.setSize %in% task, data = osss))
whereas in package:nlme (and in package:lme4)
osss.lmL <- lmList(logOdds ~ c.setSize %in% task | subj, data = osss)
# Error in `contrasts<-`(`*tmp*`, value = "contr.treatment") :
# contrasts can be applied only to factors with 2 or more

Ceph + RBD + Xen: Complete collapse -> Network issue in domU / Bad data for OSD / OOM Kill
Hi,
A bit of explanation of what I''m trying to achieve :
We have a bunch of homogeneous nodes that have CPU + RAM + Storage and
we want to use that as some generic cluster. The idea is to have Xen
on all of these and run Ceph OSD in a domU on each to "export" the
local storage space to the entire cluster. And then use RBD to store /
access VM images from any of the machines.

Multihomed question: want Lustre over IB andEthernet
Chris,
Perhaps you need to perform some write_conf like command. I''m not sure if this is needed in 1.6 or not.

ldiskfs-ext4 interoperability question
Our current Lustre servers run the version 1.8.1.1 with the regular ldiskfs.
We are looking to expand our Lustre file system with new servers/storage and upgrade to all the lustre servers to 1.8.4 as well at the same time. We
would like to make use of the ldiskfs-ext4 on the new servers to use larger OSTs.
I just want to confirm the following facts:
1. Is is possible to run different versions

How to track down a latency/timing problem
Hello Lustre Experts
I am trying to solve a problem with very slow "ls" and other big amount
of file operations but good overall read/write rates.
We are running a small cluster of 3 OSSs with 9 OSTs, 1MDS (with SSD
MDT) and currently two clients. All server nodes are centos 5.2 with
lustre 1.8.1 while the clients are centos 5.4 with lustre 1.8.3. All
components are networked with DDR

OSD Mystery
I recently started using compiz-fusion. After spending months looking
at an anemic little rectangular on-screen volume control when I use
the volume buttons on my ubuntu thinkpad T60p, all of a sudden I
noticed that I was getting a nice, big, robust rounded-corner display
(somewhat mac-like). Now it's gone again.
I really have no clue whether this came from compiz-fusion, emerald, a
plugin,

NFS Performance
Hi,
With help from Oleg we got the right patches applied and NFS working
well. Maximum performance was about 60 MB/sec. Last week that dropped
to about 12.5 MB/sec and I cannot find a reason. Lustre clients all
obtain 100+ MB/sec on GigE. Each OST is good for 270 MB/sec. When
mounting the client on one of the OSSs I get 230 MB/sec. Seems the
speed is there. How can NFS and Lustre be tuned

[PATCH 3/3]:Staging: hv: Remove osd layer
The OSD layer was a wrapper around native interfaces
adding little value and was infact buggy -
refer to the osd_wait.patch for details.
This patch gets rid of the OSD abstraction.

sse, mmx support for hvm guests
Hi,
I''ve a quad-core x86_64 machine (Intel Xeon), with sse/mmx support.
However, I want to disable sse/mmx support from HVM guests. How can I
do this? Also, is it reasonable to expect illegal instruction fault in
non-root VMX mode if a guest VM runs an application with sse/mmx
instructions?
Thanks,
Ashish

[LLVMdev] compile linux kernel
does that mean .o generated with gcc (.c -> .s and .s -> .o) will not
contain llvm ir?
i meant, final kernel bitcode ir arch independent and can be JIT with
any arch-specific backend. Is it not the case?
thanks,
ashish

Interested in contributing to Lustre
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:

[LLVMdev] compile linux kernel
No, this is not the case.
Just because you compile something to LLVM IR does not make the thing
you compiled work on every architecture.
You may even be able to retarget it to any architecture (it depends),
but this in no way means the result will *actually work*.
The LLVM IR generated by llvm-gcc is very architecture dependent.
Theoretically you could make a C compiler that was mostly C
