Enable or disable access time tracking

You can enable access time tracking to support features that require it.

About this task

By default, the Isilon cluster does not track the timestamp when files are accessed. You can enable this feature to support OneFS features that use it. For example, access-time tracking must be enabled to configure SyncIQ policy criteria that match files based on when they were last accessed.

Enabling access-time tracking may affect cluster performance.


  1. Click File System Management > File System Settings > Access Time Tracking.
  2. In the Access Time Tracking area, click the Enable access time tracking check box to track file access time stamps. This feature is disabled by default.
  3. In the Precision fields, specify how often to update the last-accessed time by typing a numeric value and by selecting a unit of measure, such as Seconds, Minutes, Hours, Days, Weeks, Months, or Years.
    For example, if you configure a Precision setting of one day, the cluster updates the last-accessed time once each day, even if some files were accessed more often than once during the day.
  4. Click Save Changes.
