Enable or disable access time tracking

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

By default, the EMC 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.

Note: Enabling access-time tracking may affect cluster performance.

Procedure

  1. Click File System Management > File System Settings > Access Time Tracking .
  2. In the Access Time Tracking area, select a configuration option.
    • To enable access time tracking, click Enabled, and then specify in the Precision fields 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 1 day, the cluster updates the last-accessed time once each day, even if some files were accessed more often than once during the day.

    • To disable access-time tracking, click Disabled.
  3. Click Submit.
