Strange Cassandra startup error

I've been running apache-cassandra 2.2.6 for a few years. Recently when I configured a new cassandra node and started Cassandra via "service start cassandra" on LINUX 6.5, I got the following exception. After cleaning out my data_file_directories I was able to successfully restart. Any ideas? Thanks

Is "/usr/share/cassandra/data" a local drive, or NFS? Anyone doing any changes to fstab / mounted volumes?
