xCAT Genesis Base
|
||||
=================
|
||||
|
||||
.. note:: Ensure that you rebuild ``xCAT-genesis-base`` with ``xCAT-genesis-builder`` version >= to *2.13.10* before updating xCAT to *2.13.10* or higher.
|
||||
xCAT ships a ``xCAT-genesis-base`` package as part of xcat-deps. This is a light-weight diskless linux image based currently on Fedora34, that is used by xCAT to do hardware discovery.
|
||||
|
||||
xCAT ships a ``xCAT-genesis-base`` package as part of xcat-deps. This is a light-weight diskless linux image based on Fedora (Fedora26, currently) that is used by xCAT to do hardware discovery.
|
||||
|
||||
To support the Power9 hardware, changes are made to the kernel in the Red Hat Enterprise distribution that are not yet available in the Fedora kernels. Without that support, running the scripts in xCAT discovery caused segmentation faults described in this issue: https://github.com/xcat2/xcat-core/issues/3870
|
||||
|
||||
Work-around
|
||||
-----------
|
||||
|
||||
.. note:: The genesis-base must be compiled on the Power9 hardware, running RHEL8. If the management node is not Power9 hardware, manually provision a RHEL8 compute node, build the genesis-base RPM, then install it on the management node.
|
||||
|
||||
xCAT cannot ship a kernel based on RHEL distribution, so the customer needs to build a version of the ``xCAT-genesis-base`` on-site using a server running Red Hat Enterprise Linux 8. Building ``xCAT-genesis-base`` on a server running Red Hat Enterprise Linux 7 is no longer supported.
|
||||
To build your own version of the ``xCAT-genesis-base`` on-site using a server running OS other than Fedora34, like Red Hat Enterprise Linux 8, follow the steps below. Building ``xCAT-genesis-base`` on a server running Red Hat Enterprise Linux 7 or earlier, is no longer supported.
|
||||
|
||||
1. Download the latest timestamp version of the ``xCAT-genesis-builder`` RPM provided here: http://xcat.org/files/xcat/xcat-dep/2.x_Linux/beta/
|
||||
|
||||
2. Install the ``xCAT-genesis-builder`` RPM on a node that is installed with the RHEL version 8.
|
||||
2. Install the ``xCAT-genesis-builder`` RPM on a node installed with desired OS (currently verified with Fedora34 and Red Hat Enterprise Linux 8). For more details: https://github.com/xcat2/xcat-core/tree/master/xCAT-genesis-builder#readme
|
||||
|
||||
3. Build the ``xCAT-genesis-base`` RPM: ::
|
||||
|
||||
/opt/xcat/share/xcat/netboot/genesis/builder/buildrpm
|
||||
|
||||
4. Install this package on top of the xCAT install and execute: ``mknb ppc64``
|
||||
To use the generated RPM from the step above for node discovery:
|
||||
|
||||
1. Install the generated ``xCAT-genesis-base`` RPM on the xCAT Management node
|
||||
2. Execute: ``mknb ppc64``
|
||||
|
||||
3. Follow :doc:`discover nodes </guides/admin-guides/manage_clusters/ppc64le/discovery/mtms/discovery.html>`

# xCAT-genesis-builder
|
||||
|
||||
xCAT-genesis-builder is a utility for building base initrd images for deploying
|
||||
diskless nodes in your cluster. This tool is required only if you have the
|
||||
intention of deploying diskless nodes within your xCAT cluster.
|
||||
`xCAT-genesis-builder` is a utility for building base initrd images for deploying diskless nodes in your cluster for discovery. This tool is required only if you have the intention of building your own version of `xCAT-genesis-base` RPM which is available in `xcat-dep` (latest version was built on Fedora34).
|
||||
|
||||
# Background
|
||||
|
||||
For every architecture in your cluster, be it x86_64, ppc64, or arm, you need to have a default
|
||||
initrd image for performing the initial boot and deploying the diskless operating system.

For every architecture in your cluster, be it x86_64, or ppc64, you need to have a default
|
||||
`initrd` image for performing the initial boot and deploying the diskless operating system.
|
||||
|
||||
If for some reason, the versions included in the xCAT repository are insufficient, you can simply
|
||||
run this utility on the target architecture which will build an RPM designed for the target
|
||||
architecture. You can then transfer that RPM to your xCAT servers, install it, and then rebuild

The `xCAT-genesis-builder` package is designed to be run from a Red Hat compatible operating system

Latest version 2.16.3 of `xCAT-genesis-builder` RPM available at https://www.xcat.org/files/xcat/xcat-dep/2.x_Linux/beta and was verified to install and run on Fedora34 and Red Hat 8. Earlier version 2.14.5 of `xCAT-genesis-builder` RPM available at https://www.xcat.org/files/xcat/xcat-dep/2.x_Linux/beta and was verified to install and run on Fedora26 and Red Hat 7.

If a new version of `xCAT-genesis-builder` RPM needs to be built:

git clone -b master https://github.com/xcat2/xcat-core.git
|
||||
```
|
||||
|
||||
2. Build new `xCAT-genesis-builder` RPM:

|
||||
cd xcat-core

./makerpm-genesisbuilder

commands:
|

```sh

rmimage rhels8.4.0-ppc64le-netboot-image

|
||||
packimage rhels8.4.0-ppc64le-netboot-image

```
|

|

Finally, attempt a re-imaging of a host using the following command:
|
||||
|
||||
```sh
|
||||
rinstall hostname
|
||||
rcons hostname
|
||||
```
|
||||
|
||||
If you rcons into the hosts, you can watch the actual initilization of the operating
|
||||
system with the resulting netboot image.

||||
