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 David Huang > Lars >_______________________________________________ >drbd-user mailing list >drbd-user at lists.linbit.com >http://lists.linbit.com/mailman/listinfo/drbd-user
