Hi Olivier,
Just to let you know that OSCAR blocked at step 6 when assigning a MAC address
to a node
(when I clicked "Assign MAC to node"). I am unable to perform " Stop Collecting
MACs" :
--> Step 6: cleaning hostfile
--> Step 6: About to run setup_dhcpd...
ERROR: Impossible to get networking data at
/usr/share/perl5/vendor_perl/OSCAR/GUI_MAC.pm line 399
ERROR: Impossible to setup dhcpd (eth0) at /usr/lib64/perl5/vendor_perl/Tk.pm
line 250
I will kill the processes and try to update all the osacar packages with
yum update all
then I will restart from the beginning with oscar_wizard.
Kind Regards,
Costel

OSCAR on CentOS-6: bootstrap successfull using online repository.
Hi Olivier,
Just to let you know my OSCAR image was built successfully this night. Do you
believe I can add
the local repository (/tftpboot/distro/rhel-6-x86_64) before epel and remote
CentOS mirrors
in order to accelerate things or is not a good idea?
I see the systemimager installed is version 0.91. I don't know if it will work
but I can give it a try.
I would execute the post-install script if needed.
Concerning the repo I thought of the same issue about the limited bandwidth.
It took longtime but it finally did the job.
I disabled iptables, SELinux (and maybe IPV6 too) from the beginning. My
previous experience
with OSCAR and Beowulf clusters was of good help.
I will also use Torque because I will certainly do not have time to setup SGE.
Keep in touch,
Costel SEITAN

Hi Costel,
I've reupdated my repository.
- I've hopefully fixed all issues with systeminstaller generating bad master
script. I've also added a few drivers (mainly network and scsi (vmware at
least)). I hope to have a far better systemimager later, but for the moment,
this somewhat old rpm should do the trick.
- I've updated a few oscar packages, and munge now should show up, and some
minor problems should be fixed as well.
- You are unfortunately hitting my repository problem: it's a non-pro web space
free of charge from my ISP and thus the bandwidth is limited. That's why it's a
"non-official" repo. The bandwidth and the size are limited due to my ISP
contract that says I need to purchase pro-space if I need bandwidth.
Anyway, keep trying, it should work in the end. Try to avoid 5PM to 9PM
French time and it should work.
- regarding openmpi, I'll give a look, it's strange......You can disable all
things that fails of course. I've also noted a tiny bug ion the torque package
post install (the alternatives are not properly set for qsub
(/etc/alternatives/qsub points at the wrong place). I'll fix that ASAP. It
should not prevent torque from installing and working though.
- regarding the image building, I had the same problem today, some epel mirrors
were very slow....
Note that the systemimager that corrects the master script generation bug is
the 0.92 release.
Note also that you may require the following pre and post install scripts to
circumvent current systemimager issues
http://olivier.lahaye1.free.fr/RPMS/extra/si_scripts.tar.bz2
I've noted that packman crashes when the package download fails. I'll add
this on my todo list.
- regarding SGE, the oscar materials are completely obsoletes. now the system
is called gridengine and there are some rpms available. I think that we need to
rewrite the whole stuff in oscar. I'll give a look when oscar for centos-6 will
be running fine. I hope to be able to use the officials gridengine rpms so I
can avoid maintaining the package. If it's possible, then we would only have to
update the opkgs.
For the moment, only torque + maui works in oscar.....(you can use gridengine
on an oscar scluster, but you'll have to configure the whole stuff by hand.
(for the moment)
IMPORTANT: I forgot to tell also that you should disable iptables and SELinux
(or set it to permissive).
I'm not sure, but if my memory is correct, I had issues in the past when ipv6
was enabled and I can't tell if I fixed the problem or not. The issue was when
oscar was parsing the /etc/hosts grepping for localhost or something like that.
Today, I was able to reach again oscar step 7 successfully.(still minor issues
in step 8 (testing))
Now, I've formatted my VMS and started again from scratch to check the
remaining issues. Now building the oscarnode image. No errors so far.
See you tomorrow.
Best regards.

Objet : RE: [Oscar-users] OSCAR on CentOS-6: how to test.(Warning,
experimental) WAS:Re: OSCAR on CentOS-6: bootstrap successfull using online
repository.
Hello,
Today I did a big step forward.
I did what you suggested and followed your list Olivier as you described into
the previous posts.
NOTE: The available repositories were:
http://olivier.lahaye1.free.fr/OSCAR/repos/unstable/rhel-6-x86_64/,
http://download.fedoraproject.org/pub/epel/6/x86_64,
http://mirror.centos.org/centos/6/updates/x86_64/,
http://mirror.centos.org/centos/6/extras/x86_64/,
http://mirror.centos.org/centos/6/os/x86_64/
(I modified the supported_distros.txt and the url was recreated with
http://olivier.lahaye1.free.fr/OSCAR/repos/unstable/rhel-6-x86_64/)
The Oscar installed OK and I successfully launched (at step 7)
oscar_wizard -d install
I selected the same packages as the one in your list.
NOTE: I do not see munge into the list of packages and it looks like during the
installation of the selected packages it downloads munge from CentOs 6
repository.
I configured the packages successfully.
It first failed at the step "Install OSCAR Server Packages" with the messages:
http://olivier.lahaye1.free.fr/OSCAR/repos/unstable/rhel-6-x86_64/openmpi-oscar-runtime-1.6.3-1.x86_64.rpm:
[Errno 12] Timeout on
http://olivier.lahaye1.free.fr/OSCAR/repos/unstable/rhel-6-x86_64/openmpi-oscar-runtime-1.6.3-1.x86_64.rpm:
(28, 'Operation too slow. Less than 1 bytes/sec transfered the last 30
seconds')
Trying other mirror.
Error Downloading Packages:
openmpi-oscar-runtime-1.6.3-1.x86_64: failure:
openmpi-oscar-runtime-1.6.3-1.x86_64.rpm from unstable_rhel-6-x86_64: [Errno
256] No more mirrors to try.
ERROR during execution 256

/usr/share/perl5/vendor_perl/OSCAR/PackMan.pm line 656.
Error occured during smart_install (-1):
at /usr/bin/install_server line 121
I noticed it is always the same .rpm file concerning openmpi. I therefore
removed openmpi from the distribution and OSCAR packges installed correctly.
However when launching "Create a SIS Image" it took longtime with messages like:
http://download.fedoraproject.org/pub/epel/6/x86_64/repodata/repomd.xml: [Errno
14] PYCURL ERROR 22 - "The requested URL returned error: 503"
Trying other mirror.
http://download.fedoraproject.org/pub/epel/6/x86_64/repodata/repomd.xml: [Errno
12] Timeout on
http://download.fedoraproject.org/pub/epel/6/x86_64/repodata/repomd.xml: (28,
'Operation too slow. Less than 1 bytes/sec transfered the last 30 seconds')
Indeed, I noticed that some of fedora repositories were hard to reach today.
After 1 hour the SIS image building is still in progress.
I will let it run till tomorrow morning and I hope that the build of SIS image
will finally go smoothly so I can pass to the first node installation.
NOTE: I suppose that SGE is somehow decommissioned or maybe you prefer Torque.
I do not have experience with Torque but it looks similar.
Kind Regards,
Costel SEITAN

WAS:Re: OSCAR on CentOS-6: bootstrap successfull using online repository.
Costel,
If you want to test, you can update the /etc/oscar/supported_distros.txt and
replace the oscar:http://official url with
http://olivier.lahaye1.free.fr/OSCAR/repos/unstable/rhel-6-x86_64/
alternative method: after the bootstrapping:
in /tftpboot/oscar/rhel-6-x86_64.url, replace the official url with
http://olivier.lahaye1.free.fr/OSCAR/repos/unstable/rhel-6-x86_64/ Note that
the url is ofter rewritten. The prefered method is the 1st one.
So:
1: rpm -Uvh
http://olivier.lahaye1.free.fr/OSCAR/repos/unstable/rhel-6-x86_64/oscar-release-6.1.2r9625-1.noarch.rpm
2: yum install oscar
3: vim /etc/oscar/supported_distros.txt
4: oscar-config --setup-distro centos-6-x86_64
5: verify that /tftpboot/oscar/rhel-6-x86_64.url contains the correct url
6: oscar-config --bootstrap
7: oscar_wizard -d install
And so on.
WARNING: This repo is not official and sometimes it's broken. be warned of that
when using it for testing.
Best regards,
Olivier.
