problema para sustituir una master con una replica

Hola lista tengo un PostgreSQL 9.5.9 y monte el siguiente escenario, que
se motiva porque tengo un postgres en producción con varias
maquinas replicas y la idea es cambiar la master a una
máquina fisica nueva, por lo tanto queremos promover una replica en la
maquina nueva y que el resto de las replicas apunte a esta nueva master::

master--replica1--replica2

antes de simular una caida de la master verifique

bash-4.2$ /opt/PostgreSQL/9.5/bin/pg_controldata /opt/test/master/ | grep
'Latest checkpoint location'
Latest checkpoint location: F/7F000098
bash-4.2$ /opt/PostgreSQL/9.5/bin/pg_controldata /opt/test/replica2/ | grep
'Latest checkpoint location'
Latest checkpoint location: F/7F000098
bash-4.2$ /opt/PostgreSQL/9.5/bin/pg_controldata /opt/test/replica1/ | grep
'Latest checkpoint location'
Latest checkpoint location: F/7E000060

procedi a simular una caida (apague la master) y promovi la replica1 a
master:

bash-4.2$ /opt/PostgreSQL/9.5/bin/pg_ctl -D /opt/test/master/ stop -m fast
waiting for server to shut down.... done
server stopped

bash-4.2$ /opt/PostgreSQL/9.5/bin/pg_ctl -D /opt/test/replica1/ promote
server promoting

apenas hice eso, la réplica2 (que estaba apuntando a la replica1) empezo a
generar el siguiente error:

LOG: consistent recovery state reached at F/7F000338
LOG: invalid record length at F/7F000338

solo cuando levante nuevamente la master y reapunte la replica2 a la
master pudo volver a sincronizar
