示例1: poolStatus
func (devices *DeviceSet) poolStatus() (totalSizeInSectors, transactionId, dataUsed, dataTotal, metadataUsed, metadataTotal uint64, err error) {
var params string
if _, totalSizeInSectors, _, params, err = devicemapper.GetStatus(devices.getPoolName()); err == nil {
_, err = fmt.Sscanf(params, "%d %d/%d %d/%d", &transactionId, &metadataUsed, &metadataTotal, &dataUsed, &dataTotal)
}
return
}示例2: deviceStatus
func (devices *DeviceSet) deviceStatus(devName string) (sizeInSectors, mappedSectors, highestMappedSector uint64, err error) {
var params string
_, sizeInSectors, _, params, err = devicemapper.GetStatus(devName)
if err != nil {
return
}
if _, err = fmt.Sscanf(params, "%d %d", &mappedSectors, &highestMappedSector); err == nil {

}示例3: initMetaData
func (devices *DeviceSet) initMetaData() error {
_, _, _, params, err := devicemapper.GetStatus(devices.getPoolName())
if err != nil {
return err
}
if _, err := fmt.Sscanf(params, "%d", &devices.TransactionId); err != nil {
