Postgresql BDR复制问题

我正在尝试设置2节点BDR复制，在运行BDR_init_copy时出现以下错误

以下是步骤：

mkdir /postgres/pgsql-9.4/data

/usr/pgsql-9.4/bin/pg_basebackup -h 10.10.145.111 -p 5432 -X stream -U postgres -D /postgres/pgsql-9.4/data

cp /postgres/pgsql-9.4/data_old/postgresql.conf /postgres/pgsql-9.4/data
cp /postgres/pgsql-9.4/data_old/pg_hba.conf /postgres/pgsql-9.4/data
chmod -R 700 /postgres/pgsql-9.4/data

/usr/pgsql-9.4/bin/bdr_init_copy -d "host=10.10.145.111 dbname=apimgtdb port=5432" -U postgres --local-dbname="host=10.10.145.110 dbname=apimgtdb port=5432" -n nodeawswest -D  /postgres/pgsql-9.4/data

我得到以下错误：

发生此错误后，它没有启动第二个节点。

我能够通过以下步骤修复一个节点上损坏的BDR：

$ mv /var/lib/pgsql-9.4/data /var/lib/pgsql-9.4/data-bkp-94
$ mkdir /var/lib/pgsql-9.4/data
$ /usr/pgsql-9.4/bin/pg_basebackup -h 10.10.145.111 -p 5432 -X stream -U postgres -D /var/lib/pgsql-9.4/data
$ /etc/init.d/postgresq-9.4 restart

不需要bdr_init_copy步骤，因为您已经将数据从节点2复制到节点1。
