Caching normal user data blocks

If you cache normal user data blocks, the WAFL external cache interprets this setting as the buffer cache policy of keep and saves normal user data blocks in the external cache.

Step

  1. To enable or disable caching for normal user data blocks, enter the following command:
    options flexscale.normal_data_blocks {on|off}

    The default value is on.

    When the flexscale.normal_data_blocks option is set to on, the WAFL external cache interprets this setting as the buffer cache policy of keep and saves normal user data blocks in the external cache.

    If this option is set to off, only metadata blocks are cached, except for volumes that have a FlexShare buffer cache policy of keep.
