Category: Installation Group: None Status: Open Resolution: None Priority: 5 Submitted By: Royden Aranha (nedyor) Assigned to: Nobody/Anonymous (nobody) Summary: OSCAR 2.2.1 unable to define clients Initial Comment: I am a final year student of I.T Engg. in Manipal Institute of Technology, Karnataka, India. We are trying to implement clustered computing using Linux, so we decided that OSCAR was good for us (after a lot of other mess ups). The hardware given to us to work on are IBM machines with intel xeon processors(2.4GHz or so). we have WinXP on one partition & RedHat7.3 on the other. We tried installing OSCAR...the initial part of which went on rather smoothly. Before i state my other doubts, i'll tell y'all where things failed. We reached the point of defining clients, gave our specifications, initially for only 2 clients, from 192.168.0.2 with no automatic reboot. We pressed the addclients button... & we almost immediately got the error: *** =============================== == Running step 5 of the OSCAR wizard: Define OSCAR clients =============================== --> Step 5: Running: ./post_clients It looks like this system is running the ipchains "service" from Redhat. Examining /etc/sysconfig/ipchains ... We need to add rules to allow these clients access: slave1.cluster slave2.cluster We need to add lines to allow client net booting. cp -p /etc/sysconfig/ipchains /etc/sysconfig/ipchains.bak Writing out modified /etc/sysconfig/ipchains file. Restarting ipchains packet filtering to catch new rules service ipchains restart Couldn't push hosts file to images at ./post_clients line 33 No such file or directory at /usr/lib/systeminstaller/SystemInstaller/Tk/AddClients. pm line 188 Couldn't run postinstall at /usr/lib/perl5/site_perl/5.6.0/i386- linux/Tk.pm line 217 *** The only thing i could relate to this was that when defining the image, we chose static IP even though we were going in for a network boot, as dynamic DHCP was not accepted (it gave us an error when defining the image). Somebody please help us out here. The other doubts that we had were: 1.) when defining the image, there was a file for the partitions desired... we rewrote the OSCAR example according to what existed on our clients. the last line in the partitions file was: nfs_oscar:/home .. ... . ... which we did not change...our master (server node) is named "master". i get the feeling we should change that last line, please tell me whether this is implicitly done or not. 2.)the first time we defined the image, 'dynamic dhcp' gave an error, so we changed it to 'static', but we could not overwrite the existing image. so we made a new one. is there an option to delete the previous image? 3.)when we got an error in dfining the clients, we were literally psyched/heart broken/torn apart/on the verge of tears... we tried doing things in different combinations, we realized that the IP addresses assigned could not be over written or reused...how do we get over this? In our sorry state... we went on mailing/posting the probelm everywhere we could...I think i have sent a mail to a 'jsquyres' & posted 1/2 this message on some forum. Sorry if I have caused any trouble, please do help me out, Royden C.

We tried running the start over script & this time it failed at the network tiem server step itself. really really confused at this time, anyone's help would really mean a lot to us thanking you, royden c. aranha ---------------------------------------------------------------------- Comment By: Jason Brechin (brechin) Date: 2003-08-06 14:16 Message: Logged In: YES user_id=274641 Do two images exist on your system now? If so, make sure that the right one is selected in the Add Clients window. ---------------------------------------------------------------------- Comment By: Nobody/Anonymous (nobody) Date: 2003-08-06 08:30 Message: Logged In: NO should try reading 749821 and 717912. could help u out prob. i'm in the middle of setting up my first cluster as well here in Malaysia. having same prob but solved partly through this forum. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=109368&aid=783917&group_id=9368 ------------------------------------------------------- This SF.Net email sponsored by: Free pre-built ASP.NET sites including Data Reports, E-commerce, Portals, and Forums are available now.
