You'll need to provide some more information. Is it under / or under something else? What was in it?

These are the yaml settings that control where cassandra stores data...

# directories where Cassandra should store data on disk.
    - /var/lib/cassandra/data

# commit log
commitlog_directory: /var/lib/cassandra/commitlog

# saved caches
saved_caches_directory: /var/lib/cassandra/saved_caches
