ClusterPack Tutorial

1.6.13 Copy files within nodes in a cluster

The 'clcp' command in /opt/clusterpack/bin is used to copy files between cluster nodes. Each file

or directory argument is either a remote file name of the form "%h:path" or "cluster:path" or a

local file name (containing no ':' characters).

Some examples of clcp usage are:

Update /etc/checklist on all nodes with the local /etc/checklist

% clcp /etc/checklist %h:/etc/checklist

% clcp /etc/checklist cluster:/etc/checklist

Update /etc/checklist on node1 and node3 with the local /etc/checklist

clcp -C node1+node3 /etc/checklist %

h:/etc/checklist

Copy multiple local files to all nodes

% clcp a.txt b.txt c.txt %h:/tmp/.

Copy multiple remote files to multiple local files

% clcp %h:/tmp/a.txt /tmp/a.%h.txt

For more details on the usage of clcp, invoke:

% man clcp

1.6.14 List a user's process status on one or more cluster nodes

The 'clps' command in /opt/clusterpack/bin is used to produce a 'ps' output that includes the host

name. A clps command with no arguments lists all the processes associated with the user

invoking the command on all Compute Nodes.

Some examples of clps usage are:

List all processes belonging to user 'joeuser'

% clps -u joeuser
