Re: [Gluster-devel] Plans for FreeBSD support?

2007-07-26 Thread Hitesh

Avati,

The idea is to be disciplined and stick to the tasks on hand, once we've 
completed *all tasks related to 1.3 stable release,* we will can 
re-evaluate the Roadmap and re-caliberate resources for FreeBSD.


For now please focus on 1.3 stable release.

Thanks

Hitesh

Attila,
Thanks again for your initial work on helping porting glusterfs to 
FreeBSD.
Based on your help we have been able to get glusterfsd to work on 
FreeBSD

and export volumes successfully.
 We are willing to provide you more active support in getting glusterfs
ported. At the time of your previous patch submission there was a 
transition
in codebase from glusterfs--mainline--2.4 to 
glusterfs--mainline--2.5, and

your patches were on 2.4, where related code were being changed in
glusterfs--mainline--2.5, hence I couldnt apply those patches 
immediately.

Apologies for the delay.
 If you can give a shot in getting the client running as well on 
FreeBSD,

we will all appretiate it a lot!

thanks again,

Hello,

I would like to reply to the following e-mail (I've just subscribed, so
this will be a new thread, sorry):
http://lists.nongnu.org/archive/html/gluster-devel/2007-05/msg00113.html 



First of all, if you need a (or more than one) FreeBSD developer
machine(s), just tell me, I can give access to them (it's possible that
installing FreeBSD on a local machine can be easier).

BTW, I've tried to compile it. I have a FreeBSD/amd64 6-STABLE machine
and glusterfs-1.3.0-pre3 (tell me if it's not the right version to 
start

with).

So far I did the following:
- gunzip/untar
- -ldl cleaning from configure
- ./configure --disable-ibverbs LDFLAGS=-L/usr/local/lib -L/usr/lib
-I/usr/include -I/usr/local/include LIBS=-lpthread CC=gcc42 
CXX=g++42

(I use gcc42 because I saw on the webpage, that at least gcc 4.1 should
be used when developing)
- make CFLAGS=-L/usr/local/lib -L/usr/lib -I/usr/include
-I/usr/local/include -DFUSE_USE_VERSION=26 CC=gcc42 CXX=g++42
(it's possible that FUSE_USE_VERSION was only needed for 1.2.3, I can't
remember, I started with that first, but thought that I should use the
newer one)

Re: [Gluster-devel] Roadmap and support questions.

2007-05-12 Thread Hitesh

Hello Francisco and Guten Tag Steffen

Wanted to introduce myself and Z Research, Inc. to you since you asked 
about commercial support; Z Research is the business face of Gluster and 
I am one of the co-founders and CEO of Z Research, Inc.


Z Research was officially formed in June 2005 by AB (Anand Babu) aka 
rooty who is the CTO and myself with the goal of commoditizing 
Supercomputing and Superstorage and in the process validating yet 
another a business model around Free Software, thus evangelizing Free 
Software and promoting the fact building businesses around Free 
Software is the way forward.


We have our roots in VA Linux Systems and our engineers were the core of 
the team that deployed the world's second fastest Supercomputer 
Thunder (Top 500 June 2004); it was a cluster of 4,096 Itanium 2 
processors (1,024 x 4-way nodes), 8TB of RAM and 200TB Storage. 
Essentially, our forte is Clustering and as you can see, we enabled 
existing File Systems to have clustering ability instead of writing 
another Clustered File System from scratch.


Gluster is a complete clustering stack comprising of components that 
address building of Clustered File Storage (GlusterFS), HPC Clusters 
(GlusterHPC), Visualization Cluster (GlusterViz - to be released in the 
future), Database Clusters (GlusterDB - to be released in the future) 
and Single System Image (GlusterSSI - to be released in the future).


Currently our focus is the storage vertical and we already have customer 
deployments for GlusterFS - Stanford SEP and a very large Oil Company; 
GlusterHPC also has been deployed in a number of places. Our customer 
base also includes the likes of GE and Thermawave.


The business model is akin to the Red Hat business model where the 
customer pays enterprise class support. We also provide full blown 
professional services around GlusterFS and GlusterHPC right from 
designing the solution, hardware selection, supervising integration of 
the hardware (done by our partners Amax  Synnex), on-site deployment 
and customer training.


Feel free to write to me if you have any queries or need more information..

Best regards  thanks

Hitesh

Will lookup his post. Thanks.

Ahum, are you talking about gluster or glusterfs? Two different cups 
of tea...


Glusterfs.
The site has a footer that says to write/call to zresearch.
For a newbie like me.. that was the first thing I saw.


I suppose it's too early to ask for commercial support yet (given 
that the
first code checkin happened less than 9 months ago)... but nobody 
will stop

you to ask for it :-)


Can the roadmap be influenced by funding?
Is this a mix open source/commercial type of setup or purely open source?

Quoting Amar S. Tumballi [EMAIL PROTECTED]:


Mic,
 Thanks for letting us know about the issue. Actually we found that 
the last

moment changes I made in rr scheduler was leading to an infinite loop of
glusterfs client :( That error is fixed now. (check the same ftp  
dir, you have
pre2.2 tarball). Also, while in our testing, found that stripe was  
not complete.
Even thats fixed now. You can try the glusterfs with same config file 
now.

Before I ask for help let me just say... wow! What an amazing product!
This has the potential to shake the SAN market profoundly. I was
disappointed in Luster because it made itself sounds like it didn't
require a SAN but you folks are strait forward and to the point. Kudos!

Now on to the problem:
The process for the glusterfs client is spiking to 100% cpu usage and
not responding (have to kill -9) whenever I add a stripe or unify
translator to the client volume spec.

There isn't anything in the client log, but the server logs show:
[Mar 03 19:11:01] [ERROR/common-utils.c:52/full_rw()]
libglusterfs:full_rw: 0 bytes r/w instead of 113

This only occurs on file writes. I can touch and read files just fine.
None of these problems appear when I just mount a remote volume
without the translator.

I'm using the latest glusterfs-1.3.0-pre2 code on centos with
fuse-2.6.3 (had to apply a patch before fuse module loaded)


My client volspec is below:

volume client0
  type protocol/client
  option transport-type tcp/client
  option remote-host 192.168.1.201
  option remote-port 6996
  option remote-subvolume testgl
end-volume

volume client1
  type protocol/client
  option transport-type tcp/client
  option remote-host 192.168.1.202
  option remote-port 6996
  option remote-subvolume testgl
end-volume

volume stripe
   type cluster/stripe
   subvolumes client1 client0
   option stripe-size 131072 # 128k
end-volume

#volume bricks
#  type cluster/unify
#  subvolumes client1 client0

Hi,
 Gluster Core team is happy to announce the release of GlusterFS v1.0-rc2.

The tarball is available at
 http://gnu.zresearch.com/pub/gluster/glusterfs/glusterfs-1.0.rc2.tar.gz

GlusterFS 1.0-rc2 Release Notes:
Focus of this release has been mainly on performance (phase-I) and
scalability. Most notable improvement is the asynchronous 
communication framework to allow fine-grained parallelism.


This release includes:
* 1.x release uses a new asynchronous communication framework to allow 
fine-grained parallelism.

* New 'write-back' translator.
* GlusterFS now controls the flow and main loop by getting rid of fuse 
stack and only use the low-level fuse interface for binding to 
VFS. This also removes a great number of unwanted getattr lookups,

thereby improving speed.
* Transport interface is separated out of protocol code and is now
loadable module.
* Simplified glusterfsd server startup arguments.

Few weeks from now you will find 2 more releases which will introduce 
massive performance boot with the following modules: ib-verbs 
transport driver (Infiniband low level RDMA), ld-preload GlusterFS 
client (direct interface, no context switches), scalable locking 
support, Vector-I/O (zero copying) and extensive POSIX compliance 
testing.

Gluster Core Team

open source application with that i want to test it but before that i 
want to know that how GLusterHPC works as cluster computing. 

When the master server is transfering the image  extensions to the 
client node than where does that image get`s store on the client and 
how client nodes will be functioning in the cluster. 


If you still want any information regarding my query feel free to ask.

What testing is it that you want to do? Do yo want to test is the
