Highlighted Changes
Restrictions and Known Issues
-
When provisioning a node with a diskfull install of RHEL 8.X and installing the NVIDIA CUDA 11 drivers and toolkit as part of the
osimage pkglist, the diskfull installation fails due to changes in the NVIDIA CUDA packages that are incompatible with kickstart installation. This issue only applies to diskfull installation; diskless installation is not impacted.There are two available workarounds for this issue:
-
The NVIDIA CUDA 11 packages can be added to the
osimage otherpkglistinstead of theosimage pkglist. This method will require an additional reboot after installation completes for the NVIDIA driver to be loaded. -
xCAT provides a sample postscript that can be used as an example of how to install the NVIDIA CUDA packages for diskfull installs instead of relying on the
osimagemechanisms. This sample postscript is available here:
