Space management daemons

The space management client uses the space monitor, recall, scout, and watch daemons to manage file systems automatically.

These daemons are included with the space management client. The space monitor daemon (dsmmonitord), the scout daemon (dsmscoutd), and the recall daemon (dsmrecalld) manage space on JFS2 and GPFS™ file systems. The watch daemon (dsmwatchd) runs only on GPFS file systems.

The daemons start when you add space management to your file systems and when you modify space-management options.

On GPFS file systems, you can use the GPFS policy engine to monitor space thresholds, search for migration candidates, and identify migrated files for reconciliation. If you use the GPFS policy engine, you can disable the space monitor and scout daemons.
