Unfortunately I've already taken down my DRBD environment. As far as I heard from my colleague who is familiar with DRBD, standby node failure doesn't prevent the master from writing data to the DRBD disk by default. If there is DRBD environment available around me, I'll try the test. And, I'd like to know whether the master waits forever because of the standby failure in other solutions such as Oracle DataGuard, MySQL semi-synchronous replication.
