RE: [Oscar-users] Client won't finish installing image

Hi Johnston:
 
During Step 6: Setup Networking, there is a button which says 'Setup Network Boot' - did you click it?
 
That button is some times elusive after installing OSCAR a few times...  ;-)
 
Cheers,
 
Bernard

This is driving me crazy.  I sent the last few hours rebuilding the head node.  As always the OSCAR install is flawless…  I run into problems when my nodes try and TFTP boot from the /tftpboot directory because it doesn’t find any pxe files.  Is OSCAR supposed to add those into the /tftpboot folder?  Does it look into the /tftpboot/rpm directory for them?  If it does, they aren’t there either because I’ve looked.

 

I can’t figure out why it worked fine on my first fedora install, but now after I’ve formatted (twice) and reinstalled OSCAR the files are not there for them to boot.  My nodes all get the correct IP address that dhcp is sending out.  I’ve also verified with the ‘rpm –qa | more tftp’ that I’m only running the OSCAR version of tftp.

 

Where should I look now?  Thanks for the support!

 

Mike

I should have added these in the last email.  Here are the errors I’m getting on the node as it connects into the TFTP server.

 

PXE-T01: File Not Found

PXE-E3B: TFTP Error – File Not Found

PXE-M0F: Exiting Intel Boot Agent

 

I thought it might be file permissions so I changed the RPM directory and everything in it to 755.  That didn’t work. L  I can’t figure out what I missed.  One thing that I thought was strange was that when I installed OSCAR before (before I wiped out the OS and started fresh) is that I didn’t have to create the “tftpboot” directory.  It was already there and all I had to do was create the “rpm” directory under it and my nodes would boot from it fine.

 

Please excuse my ignorance.

No, I did copy all the RPM’s into the /tftpboot/rpm directory, but isn’t there supposed to be a few configuration files in the /tftpboot directory as well?  I forgot the names of them but it was something like pxeboot.cfg and some other directories.  I noticed them on the system before and thought that the OSCAR install put them there, but I guess it didn’t.  Did I do something wrong?  Thanks again!

Hi Johnston:

 

Did you forget to copy the RPMs from each CD to /tftpboot/rpm?

 

I'm confused.

 

Cheers,

 

Bernard

Well, more problems that I didn't have before.  Before I installed OSCAR on my clean OS I had to creat the directory 'tftpboot' and 'rpm' under that to put all the RPM files.  Now for some reason I'm at the point to push the image out and it says there isn't any files.  When I look in the tftpboot directory I only see my 'rpm' directory that I created before.  I don't see the files that should be there.  Did I skip something?  I've been going through the steps and each has been successful to this point.  Thanks for the support.

Hey Johnston:

 

Others correct me if I'm wrong, but there shouldn't be any issues by creating your image with updated RPMs, it's just that we do not recommend you update your headnode prior to installing OSCAR.

 

You can chroot to your image and run updates on it (after it is built), for instance:

 

chroot /var/lib/systemimager/images/oscarimage

 

Cheers,

 

Bernard

Thank you for replying Bernard.  I kind of figured that I might have installed the updates too soon so I'm now in the process of reinstalling the OS again.  This time I'm going to install OSCAR first thing.  I really hope it works this time.

 

How would you recommend I do updates after it's done?  I mean after I get the image pushed out to all the nodes and its working.  Setting up a yum repository or something like that?  Is there a way to add all the updated RPM's into the image before you push it out?  Thanks again for your help!

Hi Johnston:

 

Can you tell us the output of:

 

rpm -qa | grep tftp

 

on your headnode?

 

Typically, we recommend you install OSCAR on a freshly installed Linux and only install updates after OSCAR has been successfully installed - not sure if this is the case, though.

 

Cheers,

 

Bernard

First off, I want to thank all you gurus who have had your hand in this.  This is an awesome management tool and I'm excited to get it going...

 

I've been testing OSCAR on a 33 node cluster running RedHat 9.0.  When I set up the server it all went very well and I could build an image and reboot my nodes and have the TFTP boot pick it up and push out the image and they would come up great.  So after this I decided to use OSCAR to help upgraded my planned migration to Fedora C2.  That's where I'm running into problems.

 

I've rebuilt my head node to Fedora 2, updated all the RPM patches and then installed OSCAR.  The nodes all see the TFTP server and start to load the OS.  The problem now is that no node will finish loading its image.  They all die at different spots in the load and I see errors like "rsync: read error: connection reset by peer" and then it dumps out to the "systemimager.org/support" message.

 

I thought it might be my gigabit switch being overloaded, so I connected the head node directly to a slave with a cross-over cable and pushed it out again.  I still have the same problem.  It crashes every time.  It looks like it has something to do with 'rsync.'  Is there anything else I can try?  Thanks for you support.

 

Mike
