Bug Description

Manila allows configuring the backend option goodness_function per backend stanza for optimizing backend balance. This option is not available in the charm.

In case of NetApp, this is needed due to a problem in the driver when using SVM scoped accounts. It does not have enough permissions to obtain the total_capacity_gb information, so it cannot calculate utilization, and therefore the goodness_function always returns 50 and end up scheduling shares always to the same pool.

The goodness_function is necessary to overcome bug [1] where the driver is not reporting the utilization correctly due to the usage of SVM-scoped account, and therefore scheduling of shares is inefficient, requiring the use of a goodness_function to create a rule such as below based on free_capacity_gb to restore good enough scheduling while [1] is not fixed.

goodness_function = "(capabilities.free_capacity_gb / 1000)"

    Add goodness-function config

    This allows specifying functions that further optimize the scheduling
    of shares across backend stanzas.

    This is needed due to a netapp-driver specific problem when using
    SVM scoped accounts. It does not have enough permissions to obtain
    the total_capacity_gb information, so it cannot calculate utilization,
