Hot standby won't start

Hello all,

I have written a script which stops postgres on my standby server, executes pg_start_backup on the master, rsync's the data directory and tablespaces over to the standby, executes pg_stop_backup on the master, and attempts to then start postgresql on the standby. My problem is the following error when I try to start postgresql on the standby:

* Starting PostgreSQL 9.1 database server
* The PostgreSQL server failed to start. Please check the log output:

I have tried running pg_resetxlog on both servers, and have verified that pg_hba.conf contains my replication user. I have also verified that the password I am supplying in my recovery.conf is correct.

Any ideas why I would get this message? I know that wal_level = hot_standby on the master and the slave.

Thanks,
Brandon
