Hi there, I’m a bit new to Linux and Cassandra so I’m hoping someone can help me with this. 


I’ve been evaluating Cassandra for the last few days and I’m now having a problem starting up the service.   I receive this error below and I’m unsure on where I’m out of space at, and how to free up more.


azadmin@cassandra-01: $ sudo /usr/tmp/apache-cassandra-0.7.6-2/bin/cassandra -f

I seem to have enough space, except in the /dev/mapper/Cassandra—01-root, and I’m unsure of that anyway:
