Some news : I was able to install the driver after installing dkms.

Now if I try to start in graphical target it doesn't work and the screen stays black.

 

I also still have to understand why the postscripts don't want to be executed.

 

Best Regards

Ok, so I tried to manually install the NVIDIA driver (card is a quadro k5000) but when I execute the .run it says the libc headers files are missing.

I checked but didn't find the package name I need...

What else do I need ?

 

And also, the postscripts I added for the driver installation and some nvidia-settings commands are not run despite being in the postscripts and osimage tables.

 

Best Regards

Hi Huette

 

When you want to add some packages from OS, you can append package short names in the pkglist. You can find the pkglist from osimage definition, then edit the pkglist to append packages like following commands:

 

~]# lsdef -t osimage rhels7.4-x86_64-install-compute -i pkglist
Object name: rhels7.4-x86_64-install-compute
    pkglist=/opt/xcat/share/xcat/install/rh/compute.rhels7.pkglist

 

 ~]# cat /opt/xcat/share/xcat/install/rh/compute.rhels7.pkglist
#Please make sure there is a space between @ and group name
wget
ntp
nfs-utils
net-snmp
rsync
yp-tools
openssh-server
util-linux
net-tools

 

 

 

Best Regards

Yes, I already know how to install a package with the installroot option :)

 

What I found weird is that some packages, including yum, weren't installed even though they are specified in the pkglist file. 

 

Whatever, I just added some packages like a desktop environment, gcc and python in the rootimg, and after a reboot yum was also working. I guess it was installed with a package I added.

 

Best Regards

The general principle is to leave things like yum out during packimage stage.

 

However, prior to packimage, you can, for example:

# chroot /install/netboot/rhels7.5/x86_64/compute/rootimg/

[root@mn10 /]#

 

To manage the image in place, and using yum externally:
yum –installroot=/install/netboot/rhels7.5/x86_64/compute/rootimage/

 

In either case, /install/netboot/rhels7.5/x86_64/compute/rootimage/etc/repos.d is what yum will complaint…

Finally I've found out that the nfs exports weren't done correctly !

After fixing it the node booted correctly :)

 

However...some basic packages like yum are missing...

I'm quite sure I don't need to put such basic packages in the pkglist file, right ?

 

Best Regards
