The master and slave servers are set up as per the tutorial https://www.digitalocean.com/community/tutorials/how-to-set-up-master-slave-replication-on-postgresql-on-an-ubuntu-12-04-vps and both servers are Ubuntu 12.04 x64 and are running PostgreSQL 9.1
below are the commands I am running and the errors I am getting, any help will be appreciated.
$ sudo su - postgres $ psql -c "select pg_start_backup('initial_backup');" $ rsync -cva --inplace --exclude=*pg_xlog* /var/lib/postgresql/9.1/main/ MAS.TER.SER.VER:/var/lib/postgresql/9.1/main/ $ psql -c "select pg_stop_backup();"
$ psql -c "select pg_stop_backup();" NOTICE: pg_stop_backup cleanup done, waiting for required WAL segments to be archived WARNING: pg_stop_backup still waiting for all required WAL segments to be archived (60 seconds elapsed) HINT: Check that your archive_command is executing properly. pg_stop_backup can be canceled safely, but the database backup will not be usable without all the WAL segments.

After running the above on the master I then set up the recovery.conf as per the tutorial and attempt to start the slave server.
$ sudo su - postgres $ nano /etc/postgresql/9.1/main/recovery.conf
Edit as per tutorial
$ service postgresql start * Starting PostgreSQL 9.1 database server * Removed stale pid file. The PostgreSQL server failed to start.
