Types

type Config

type Config struct {
	// Bitrot will perform bitrot scan on local disk when checking objects.
	Bitrot bool `json:"bitrotscan"`
	// maximum sleep duration between objects to slow down heal operation.
	Sleep   time.Duration `json:"sleep"`
	IOCount int           `json:"iocount"`
}

Config represents the heal settings.

func LookupConfig

func LookupConfig(kvs config.KVS) (cfg Config, err error)

LookupConfig - lookup config and override with valid environment settings if any.
