The scout daemon

The scout daemon automatically searches for candidates on each file system or storage pool in a file system for which space management is active.

The scout daemon scans file systems and stores the information for each file in a complete file index (CFI). The daemon works with the CFI to search for migration candidates. The CFI is updated automatically during all migration, recall, and restore operations.

To specify how often the scout daemon scans a file system, modify the setting on the candidatesinterval option in the dsm.sys file.

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