# Test UPDATE messages sent by other nodes when the currently authorirative
|
|
# master is unavaialble. The test is performed in the following steps:
|
|
#
|
|
# 1) Master goes down.
|
|
# 2) Slave failover and becomes new master.
|
|
# 3) New master is partitoned away.
|
|
# 4) Old master returns.
|
|
# 5) At this point we expect the old master to turn into a slave ASAP because
|
|
# of the UPDATE messages it will receive from the other nodes when its
|
|
# configuration will be found to be outdated.
