Erro de serviço de réplica Postgres 10 na inicialização

Migrei um banco de dados promovendo a réplica de leitura em um servidor com mais capacidade, esse processo funcionou sem problemas. Mas estou tentando criar uma réplica de leitura agora a partir deste servidor promovido para ter uma configuração semelhante à que eu tinha antes. O problema é que quando tento iniciar o servidor Postgres isso acontece.

● postgresql-10.service - PostgreSQL 10 database server
   Loaded: loaded (/usr/lib/systemd/system/postgresql-10.service; disabled; vendor preset: disabled)

   Main PID: 22746 (code=exited, status=2)

Vou descrever meu processo o mais preciso possível, estou rodando no CentOS RHEL 7.

Primeiro eu instalo o Postgres 10:

rpm -Uvh https://yum.postgresql.org/10/redhat/rhel-7-x86_64/pgdg-centos10-10-2.noarch.rpm
yum install postgresql10-server postgresql10
yum install postgresql10-contrib
su - postgres
/usr/pgsql-10/bin/initdb
systemctl start postgresql-10.service

Isso funciona, o servidor está rodando então a instalação funcionou, vamos começar com a replicação. Eu paro o serviço e continuo com isso:

 rm -r /var/lib/pgsql/10/data
 su - postgres
 /usr/pgsql-10/bin/pg_basebackup -h <database host ip> -D /var/lib/pgsql/10/data/ -P -U replicate

replicateé o usuário com privilégios de replicação no banco de dados principal.

O pg_basebackupfinaliza corretamente, então renomeio o recovery.donepara recovery.conf.

Mas ao correr systemctl start postgresql-10.service, eu recebo

O trabalho para postgresql-10.service falhou porque o processo de controle foi encerrado com código de erro. Consulte "systemctl status postgresql-10.service" e "journalctl -xe" para obter detalhes.

Não consegui encontrar mais pistas do que esta única mensagem:

postgresql-10.service: main process exited, code=exited, status=1/FAILURE

o que estou perdendo? Já tentei rodar com o padrão postgres.confe pg_hba.confevitar erros de configuração mas também não funcionou.
