I have been using an OS-x 64 Node cluster and i have developed an
admin script that does allot of my management for me, i thought i
would post it here for others if they are interested in it.
#!/bin/tcsh
if (${1} == "") then
echo 'This is the primary admin script for the cluster, you
must be root and have '
echo 'admin privelegs and a ~/pss file to run it. the
following comands are available '
echo
echo 'cladmin shutdown <start> <end> -- shuts down the
indicated cluster nodes'
echo 'most likely you really want restart '
echo
echo 'cladmin restart <start> <end> -- this shuts down and
restarts a range of nodes '
echo
echo '----- do not use shutdown and restart on node 1 under
any circumstatnces ------'
echo
echo 'cladmin stat <start> <end> <procname> -- this
performas a stat on the cluster nodes '
echo ' it gives all the procceses ofr just the <procname>'
echo
echo 'cladmin st <start> <end> -- this is joes short
version of stat '
echo
echo 'cladmin killam <start> <end> -- this is an attempt to
fix the lam system it may or may not work '
echo
echo
echo 'cladmin update <start> <end> "<Package name and
location>" -- this wil install apple packages. '
