Thierry,
I agree with Bernard that the c3.conf you posted was not properly generated, which would likely affect other portions of the installation.
The c3.conf configuration file is generated at the end of "Step 5: Define OSCAR Clients" (aka 'post_clients' phase). (It is also run whenever you add/del nodes and possibly when you add/del
pkgs.)
Anyway, the format should be as follows assuming:
My configuration is : head.node (server)=oscar1
nodes (compute)= oscar2,oscar3,oscar4.oscar5
(1) Your headnode is named 'oscar1' and is connected to the
internal/cluster interface
(2) Your compute nodes are named oscar2, oscar3, oscar4, oscar5
(3) You want to skip the zero'th index, i.e., you want to refer
to compute node1 as ":1" and not ":0", e.g.
cexec :0 hostname
vs.
cexec :1 hostname
/etc/c3.conf ------- cluster oscar_cluster { oscar1 dead remove_for_0-indexing oscar2 oscar3 oscar4 oscar5 }
You can manually edit the file to see if you can run simple commands.
After that I'd check the oscarinstall.log file to see if there were any
errors related to C3, possibly something like:
"I coudn't manage to update the C3 configuration!"Hope that helps, --tjn

I'm curious why your c3.conf have missing nodes (oscar2 - oscar5). Have you by any chance skipped some steps (eg. Complete Cluster Install)?
You might want to add those nodes in for now, and see if that helps...
When you say 'post configuration tests', you refer to the 'Test Cluster Setup' step correct?
BTW, the environment variable is C3_RSH (underscore between 'C3' and 'RSH').
Cheers,
Bernard

Hi
After installation of OSCAR 4 on RH-EL-AS-3 cluster(1386) all the post configuration test have succed [PASSED] 100%
My configuration is : head.node (server)=oscar1 nodes (compute)= oscar2,oscar3,oscar4.oscar5
But C3 commands don't run correctly using default settings. Here is the detail, thanks in advance for any help:
/etc/c3.conf ------- cluster oscar_cluster { oscar1 dead remove_for_0-indexing }
Also I do [EMAIL PROTECTED] C3 RSH='ssh -x' [EMAIL PROTECTED] uptime the result cexec command is bad [EMAIL PROTECTED] etc]# cexec uptime ************************* oscar_cluster *************************
I always got this result [EMAIL PROTECTED] cexec ls /home ************************* oscar_cluster *************************
[EMAIL PROTECTED] etc]# cexec oscar_cluste ls ************************* oscar_cluster *************************
[EMAIL PROTECTED] etc]# cexec :1,2 ls ************************* oscar_cluster *************************
What I have to do may be to complete the configuration setting (ssh works fine and rsync also)
any help will be appreciated
Thierry
