Hi Michael.
Definetly, something is missing in the installation. I performed
again the complete installation making sure to include the line
"192.168.0.1 marsu.cluster" in /etc/hosts but at the end I still
got the same error during the step 8 "Test cluster setup".
Probably the error comes from not having the libaio package you
mentioned but maybe something else is missing :(. I will start
another thread to see if someone who has actually installed OSCAR 5.0
using Mandriva can help me.
Thanks for your help, I learned a lot !!

As you are rather far along, you should run /opt/oscar/scripts/
start_over at least before running install_cluster again, if not
reinstalling Mandrivia. start_over is fairly good these days, so
that should be sufficient.
I have never used Mandrivia before, but I do not think the two
packages are the same. It is possible, since I don't really know
what the purpose of libaio package is either. I know things break
if its not installed, thats all :)
My guess if you poke around the internet you can find a libaio
package for mandrivia but I don't know where they would be (since I
don't use it).

Ok.
I did not find the libaio package in my distribution what I found
was this:
"libao2-0.8.5-4mdk.i586.rpm"
Is this the same package you were referring to?
Regarding the use of a fully qualified hostname (marsu.oscardomain
in my case). I did that and then I ran the oscar installation
program again, but step 8 still cannot be completed. Should I
uninstall oscar first, before running the command "./
install_cluster eth1"?.
thanks.

It also appears you are missing the libaio package which is a
prerequisite and is probably on the distribution CDs (and
therefore probably in your /tftpboot directory already). This has
been popping up a fair bit lately, so I am not sure why we didn't
see it in beta testing. You may be using a different setup than
the testers for Mandrivia. We should probably post the testing
matrix, including distro and used package sets where applicable.

OSCAR requires a fully qualified domain name for the head node
(which it then uses to name the rest of the nodes). It does not
have to be a "real" domain name as long as you are on a local
subnet, where the names are not important to anyone else. What I
usually do is use oscarhead.oscardomain for example, which isn't
"legal" but satisfies OSCAR. You can make it the domain for your
university as well, whatever you like. Like I said, it is only
for your local DNS on your cluster anyway, so it shouldn't cause
anyone else any problems.
So in your case you would need defined (at the lest in /etc/hosts,
probably could do this with "hostname" also)
127.0.0.1 localhost localhost.localdomain
192.168.0.1 marsu marsu.oscardomain
Then oscar would add the later nodes as
192.168.0.2 oscarnode01.oscardomain
I am not certain where the problem comes in when you do not have
the domain name, but I know that has been in the docs for a long
time, so I assume it breaks something if it is not there :)

Hi
I logged in the client node as root. Both the loopback device and
the network adapter (eth0) are active.
I am sending a "gzipped" file of the installation log. I just have
one since I started over from the installation of the mandriva in
the server.
Anywau, there is one detail I am not completely confident about.
It is related to the hosts definitions. Before I started the OSCAR
installation I defined the host name using the command "Hostname"
as root. But, I did not specify any hostname during the
configuration of the network interfaces. After, OSCAR was
installed, I got these hostnames:
IP address Hostname
127.0.0.1 localhost
192.168.0.1 marsu (this is the name I specify with the hostname
command)
192.168.0.2 oscarnode01.oscardomain (this was specified be the
OSCAR installation program)
regards.

You can try to log in, but only root will probably work. You
don't need to log into the client nodes to complete setup, I was
just not sure where you were exactly.
You could log in to the node and check to see that the network
card is set up properly (using "ifconfig"). I suspect that only
the loopback device will be active and not "eth0" (or whichever
adapter you chose when you ran "oscar_install").
If this is not the case, please go into your oscar install
directory (probably /opt/oscar) and do:
tar czvf logs.tgz oscar_install.*
and send the zip file that makes.

Hello.
Yes, I wanted mandriva 2006 on the client node and I think that
is what I got. After the image was installed the client rebooted
itself and I got the following in its screen:
"Mandriva Linux release 2006.0 (Official) for i586
Kernel 2.6.12-12mdksmp on a Dual-processor i686 / tty1
oscarnode01 login: "
Should I login in the client node?. which login name should I use?.
Thanks!

I hope you want mandrivia 2006 on the client node when you are
finished and not windows xp.
Did the client node get imaged, and then boot successfully to a
mandrivia text login prompt?
If the client node has not been successfully imaged, and the
"Complete Cluster Setup" step run, then the tests will not succeed.
If this sounds familiar, please attach any oscarinstall.log
files in your /opt/oscar directory, preferably compressed.

Hello.
I am trying to use OSCAR 5.0 with Mandriva 2006 in order to
cluster two computers. The server node has Mandriva 2006
installed whereas the client has windows XP. I managed to run
the cluster installation program until to step 7, "Complete
Cluster Setup", without any apparent problem. However, it was
not possible to complete step 8, "Test Cluster Setup". This is
the output I got:
" "
Performing root tests...
Maui service check:maui [PASSED]
TORQUE node check [PASSED]
TORQUE service check:pbs_server [PASSED]
/home mounts 1 nodes failed [FAILED]

SSH server -- node
[EMAIL PROTECTED]
e01.oscardomain's password:
" "
So, besides the "FAILED" message in line 5 of the output, I was
asked for a password (last line). I have not idea which password
I should use. Moreover, during the installation of OSCAR you are
not required to use any password!.
Could somebody tell me what the problem might be?
