PowerScale OneFS 9.5.0.0 CLI Administration Guide

Enable or disable access time tracking

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

By default, a PowerScale 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.
  1. Enable or disable access time tracking by setting the atime_enabled system control.
    • To enable access time tracking, run the following command:
      sysctl efs.bam.atime_enabled=1
    • To disable access time tracking, run the following command:
      sysctl efs.bam.atime_enabled=0
  2. To specify how often to update the last-accessed time, set the atime_grace_period system control.
    Specify the amount of time as a number of milliseconds.
    The following command configures OneFS to update the last-accessed time every two weeks:
    sysctl efs.bam.atime_grace_period=1209600000
