Readme file for IBM ® Spectrum LSF Suite 10.2.0.14 Fix 602092

Abstract

This fix enhances the lsfd service to 1) prevent user jobs from being killed if LSF_DAEMON_WRAP is enabled when it stops the lsfd service, and 2) Ensures that LSF only uses .pid files can get the lim, res, and sbatchd daemon process IDs.

Description

Readme documentation for IBM Spectrum LSF Suite 10.2.0 Fix 602092 including installation-related instructions, prerequisites and co-requisites, and list of fixes.

This fix addresses the following issues:
1. If the LSF_DAEMON_WRAP parameter is enabled in the lsf.conf configuration file, user jobs are killed when the lsfd service is stopped.

2. Using  the ps -ef command to get LSF daemons to processes IDs and kill them is not safe. LSF should only use .pid files to get the lim, res, and sbatchd daemon process IDs.
