[jgreen ~] si_prepareclient --help ... --my-modules Only include the modules that are currently loaded on this machine when creating the UYOK (Use Your Own Kernel) initrd.img. Without this option, all available modules are included whether or not they are currently in use (except for those listed in the /etc/systemimager/UYOK.modules_to_exclude file). Including all modules allows your UYOK kernel and initrd.img to be used with a greater variety of client hardware, but can make the resultant initrd.img much larger. ..... With client nodes of the same hardware makeup as the head node, you can use this flag to keep things of reasonable size, and ensure the kernel and initrd are exactly like the head node. If you don't, then everything gets included. So I think in either case, you'll probably get the module you need, and if you don't do this, then you'll get lots of extra stuff, too. --Joe

Is there a way to insert the cciss module with this manual setup? Thanks again.

When I've done it, I follow this doc: http://svn.oscar.openclustergroup.org/trac/oscar/wiki/InstallGuideClusterInstall#a5.8.4UseYourOwnKernelUYOK <http://svn.oscar.openclustergroup.org/trac/oscar/wiki/InstallGuideClusterInstall#a5.8.4UseYourOwnKernelUYOK> --Joe ________________________________ From: Giacomo Carella [mailto:stripp...@hotmail.com] Sent: Mon 2/22/2010 11:23 AM To: oscar-users@lists.sourceforge.net Subject: Re: [Oscar-users] Node Kernel panic Dear Joe, I'm not sure I've understood your answer. I'm a newbie in oscar, so be patient. In setup networking I've checked enable UYOK and setup network boot. As far as I can understand oscar creates initrd and kernel accordingly and puts it in /tftboot. Is this correct or should I've to generate/copy there something? Thanks Giacomo ________________________________ Date: Mon, 22 Feb 2010 10:02:32 -0600 From: joseph.greens...@ngc.com To: oscar-users@lists.sourceforge.net; oscar-users@lists.sourceforge.net Subject: Re: [Oscar-users] Node Kernel panic for the UYOK, did you copy the kernel you generated as well as the initrd image? --Joe ________________________________ From: Giacomo Carella [mailto:stripp...@hotmail.com] Sent: Mon 2/22/2010 10:00 AM To: oscar-users@lists.sourceforge.net Subject: [Oscar-users] Node Kernel panic Dear All, I'm trying to install oscar 6.0.5r9167-1 on Centos 5.4 x86-64. The head node is an HP dl145 g3. All the nodes are HP bl465. These nodes mounts the Smart Array E200i controller, while the head node not, so I've to use the cciss driver for the nodes. I've added a modprobe.conf file in /var/lib/systemimager/overrides/image-name/etc. This is the content of the file. alias eth0 bnx2 alias eth1 bnx2 alias scsi_hostadapter cciss I was able to complete smoothly all the step from 1 to 5. During step 6 the system was able to sync the image on the first node (I enabled UYOK). When the node rebooted I'd the error kernel panic, not able to find root file system in /dev/root. It seems that I've problem in creating a proper initrd/vmlinuz for the client. Can anyone help please. Thanks in advance Giacomo ________________________________ Hotmail: Trusted email with powerful SPAM protection.
