I thought this would be simple. I guess not.
I have an external hard drive mounted at /root/storage - OK
I moved the data directory from /var/lib/cassandra/ to /root/storage - OK
I then created a symbolic link out of /var/lib/cassandra pointing to where the directory is now.....so...... ln -s /root/storage/data /var/lib/cassandra - OK
Now I am unable to start cassandra. I am getting this error in /var/log/cassandra/system.log:

The permissions are exactly the same on this directory. All file permissiosn are teh same too. Any ideas would be appreciated.
When I get rid of the sym link and move the data directory back, everything works again.
