The space monitor daemon

The space monitor daemon monitors space usage on all file systems and the storage pools in those file systems to which you add space management. It starts threshold migration whenever necessary.

To check space usage more frequently or less frequently, change the value on the checkthresholds option in the dsm.sys file. To reconcile your file systems more frequently or less frequently, change the value on the reconcileinterval option in the dsm.sys file. When you change the option values the space monitor daemon uses, the new values are not effective until you stop and restart the space monitor daemon.

The space monitor daemon starts automatically when you mount the file system and add space management to it. If the space monitor daemon stops running, issue the dsmmonitord command to start it.

When GPFS™ policy drives automatic migration, disable the space monitor daemon by setting the option hsmdisableautomigdaemons=YES.
