2.3 Upgrading Moab
Moab is designed to make the upgrade process short and simple. Previous versions of Moab do not need to be uninstalled before installing a new version. Installing a new version on top of an old version will not overwrite config, log, or statistical files.
To upgrade Moab
- Untar the distribution file.
- Navigate to the unpacked directory.
- Configure the installation package.
- Stop Moab.
- All jobs continue to run on the nodes.
- The job queue remains intact.
- New jobs cannot be submitted to Moab.
- Install Moab.
- Verify the version number is correct before starting the new server version.
- Start Moab.
> tar -xzvf moab-5.3.0.tar.gz
> cd moab-5.3.0
Use the same configure options as when Moab was installed previously. If you cannot remember which options were used previously, check the config.log file in the directory where the previous version of Moab was installed from.
For a complete list of configure options, use ./configure --help.
