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
