The external script will be called with TEST parameter if the
policy is executed in test or prepare mode.
It will only get the LIST files to concat the ouput when the policy
is fully executed.

Information Lifecycle Managment (ILM) via GPFS policy engine

The GPFS policy engine is well described in this white paper. A good presentation overview of the policy file is here. The relavent documentation is available from IBM.

This project focuses on scheduled execution of lifecyle policies.

A policy is executed via the run_job

submit-pol-job

Where:

outdir - the directory for the policy and job output, should be global to cluster policy - path to the policy file nodecount - number of nodes in the cluster that will run the policy corespernode - number of cores on each node to reserve partition - the partition used to submit the job

The policy run can be scheduled automatically with the cronwrapper script. Simpley add append the above script and arguments to the crownwrapper in a crontab line. For example to run it every morning at 4 am you would add:

0 4 * * * /path/to/cronwrapper submit-pol-job
