DRBD provides block-level, live replication of data, isn't it?

>(mounting, even accessing the lower level device is a big no-no!)

what you mean is that I shouldn't stop DRBD anytime if possible?

the reason I am thinking to stop DRBD service is because I like to do scheduling replication.
Because there are numbers of LV(15~20) on my system, i was assuming that if all of the LV do the replication at the same time, there will be performance issue. It's why I was thinking to run DRBD only in the off-peak time. 

Is there any testing report about using large number of DRBD devices at the same time? 

thanks for answering my questions
