xcat-tools

Useful tools for xCAT

Installation / Update

Quick Install (into $HOME/xcat-tools)

export QS_GIT_REPO=https://github.com/ncsa/xcat-tools
curl https://raw.githubusercontent.com/andylytical/quickstart/master/quickstart.sh | bash

Customizable install options

:information_source: NOTE: Install also touches $HOME/.bashrc and $HOME/.bashrc.d, regardless of XCAT_TOOLS_INSTALL_DIR

Usage

Postscripts

Postscripts are installed into /install/postscripts/custom.

Add these to the xCAT postscripts table using the path custom/<SCRIPTNAME> ... EXCEPT for those noted below

EXCEPTION: For postscripts that have the same name as an xCAT-provided postscript, the original (file in /install/postscripts) will be moved aside (renamed with a timestamp suffix) and a symlink created that points to the custom copy (file in /install/postscripts/custom.) When specifying these scripts in the postscripts table, do NOT include the custom/ path. Specify them as normal, using just the scriptname itself. (The original scripts expect to be found and run from /install/postscripts and expect to source and include other scripts from that directory. The symlink will allow xcat to find the script in the expected location.)
