I thought it would be easy. Probably not.
I have an external hard drive installed in /root/storage - OK
I moved the data directory from /var/lib/cassandra/ to /root/storage - OK
Then I created a symbolic link from /var/lib/cassandra indicating where the directory is now ..... so ...... ln -s /root/storage/data /var/lib/cassandra - OK
Now I can’t start the cassandra. I get this error in /var/log/cassandra/system.log :

The permissions in this directory are exactly the same. All permissiosn files are the same too. Any ideas would be appreciated.
When I get rid of the sym link and move the data directory back, everything will work again.
