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.
