> , let's introduce a new option, it should be very safe, but really useful
> for some corner case. e.g. when SNN losts local storage, we need to reset
> SNN, but in current trunk, it'll always get a FATAL msg and could never be
> successful. Another workaroud for this case, is full-sync the "current"
> directory from ANN, but it'll be cost more disk-space & net bandwidth, IMHO.
