To locate your data try the following command:
sudo find / -name postgresql.conf
The problem probably is that your server isn't automatically started. You can manually start it with a command like:
pg_ctl start -D <your data dir>
If you need help starting it automatically please specify which os/distribution you are running and how you installed postgresql (source/yum/rpm/...)
The message "The database system is starting up." does not indicate an error. The reason it is at the FATAL level is so that it will always make it to the log, regardless of the setting of log_min_messages:

After the rsync, did you really run what you show?:
pgsql -c "select pg_stop_backup();";
Since there is, so far as I know, no pgsql executable, that would leave the backup uncompleted, and the slave would never come out of recovery mode. On the other hand, maybe you really did run psql, because otherwise I don't see how the slave would have logged such success messages as:
Log: consistent recovery state reached at 0/BF0000B0
and:
Log: streaming replication successfully connected to primary
Did you try connecting to the slave at this point? What happened?
The "Success. You can now start..." message you mention is generated by initdb, which shouldn't be run as part of setting up a slave; so I think you may be confused about something there. I'm also concerned about these apparently conflicting statements:
The only ways I have restarted Postgres is through the service
postgresql-9.1 restart or /etc/init.d/postgresql-9.1 restart commands.
After I receive this error, I kill all processes and again try to
restart the database...
Did you try to stop the service through the service script? What happened? It might help in understanding the logs if you prefixed lines with more information. We use:
log_line_prefix = '[%m] %p %q<%u %d %r> '
The recovery.conf script looks odd. Are you copying from the master's pg_xlog directory, the slave's active pg_xlog directory, or an archive directory?

While I don't know what specific config file is pointing to that location, it can be specified when you run the initdb command, which it's sounding like you may not have run yet, given the error you're seeing.
If you just installed a new/upgrade postgres instance, you'll probably want to use a new data directory from whatever your old instance was using (i.e. you can just run the
initdbcommand with no additional params, and it will use the default/usr/local/pgsql/datalocation which, apparently, is not yet in use for your machine), then you can export/import the old data if you still need it.
