Functions

func GetConfigStoreName

func GetConfigStoreName(nodeName string) string

func LoadOSDDirMap

func LoadOSDDirMap(kv *k8sutil.ConfigMapKVStore, nodeName string) (map[string]int, error)

func PopulateCollocatedPerfSchemeEntry

func PopulateCollocatedPerfSchemeEntry(entry *PerfSchemeEntry, device string, storeConfig rookalpha.StoreConfig) error
