what is the cmd？the default checkpoint method is spread,so pg_basebackup will wait the checkpoint complete on the master.you can set the checkpoint method to fast to avoid the waiting.

It appears that there are long pauses - up to a couple of minutes - between relatively short bursts of disk activity.I'm not noticing any lock requests outstanding. What might I be missing?__________________________________________________________________________________
