High Performance Linux Clusters with OSCAR, Rocks, OpenMosix, and MPI [Electronic resources] نسخه متنی

8.3 Notes for OSCAR and Rocks Users

Since OSCAR
installs and uses SIS, much of this material probably seemed vaguely
familiar to you. OSCAR uses SystemInstaller to build the image
directly on the server rather than capture the image from a golden
client. However, once you have installed OSCAR, you can use the SIS
scripts as you see fit.

The configuration file for

rsync is in
/etc/systemimager/rsync. OSCAR stores the
SystemImager files in /var/lib/systemimager. For
example, the image files it creates are in
/var/lib/systemimager/images.

Rocks uses Kickstart. It uses XML files to
record configuration information, dynamically generating the
Kickstart configuration file. Changing these XML files is described
in Chapter 7. You can interactively
re-Kickstart a compute node with the
shoot-node command. See the manpage
shoot-node(8) for more details.
