Cassandra data files are located at /var/lib/cassandra/data ( http://cassandra.apache.org/doc/latest/configuration/cassandra_config_file.html#data-file-directories )
Can you double check that the Cassandra process has write access to this directory? There should be a number of SSTable files in the directory if Cassandra has written the data to disk. When you start Cassandra the system log will also show each SSTable being loaded. It could be possible that something is stopping the memtables from being flushed to disk or being read by Cassandra.
