2.3 Upgrading Moab

Upgrading Moab may require changing the database.  Please see the README.database file included in the Moab distribution for specific version information.

To upgrade Moab

1. Untar the distribution file.

> tar -xzvf moab-5.3.0.tar.gz

2. Navigate to the unpacked directory.

> cd moab-5.3.0

3. Configure the installation package.

   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.

4. Stop Moab.

The Moab server must be stopped before the new version is installed.

 > mschedctl -k

moab will be shutdown immediately

While Moab is down: All jobs continue to run on the nodes. The job queue remains intact. New jobs cannot be submitted to Moab.

5. Install Moab.

> sudo make install

Moab should be installed by root. If you cannot install Moab as root, please contact Customer Support.
