Re: Questions about nsd-control zonestatus

one more question:

# nsd-control zonestatus
zone:   at
        state: ok
        served-serial: "2018011732 since 2018-01-17T15:23:57"
        commit-serial: "2018011732 since 2018-01-17T15:23:57"



# nsd-control force_transfer at
ok

# nsd-control zonestatus
zone:   at
        state: refreshing
        served-serial: none
        commit-serial: none
        notified-serial: "0 since 2018-01-17T15:34:17"
        transfer: "TCP connected to 83.136.34.20"


IS this correct behavior? It is confusing that, during the transfer the
served-serial and commit-serial is "none".

Thanks
