Hi Hari,
C* will use your entire space - that is something one should monitor.
Depending on your choose on compaction strategy your data_dir should not
be filled up entirely - in the worst case compaction will need space as
large as the sstables on disk, therefore 50% should be free space.
The parameters used for on disk storage are commitlog_directory and
data_file_directories and saved_caches_directory. The paramter
data_file_directories is in plural, you can easily put more than one
directory here (and you should do this instead of using RAID).
Cheers,
Jan

Hi Team,
We have a 3 node Apache cassandra 2.0.4 setup installed in our lab
setup.We have set data directory to /var/lib/cassandra/data.What would
be the maximum
disk storage that will be used for cassandra data storage.
Note : /var partition has a storage capacity of 40GB.
My question is whether cassandra will the entire / directory for data
storage ?
If no, how to specify multiple directories for data storage ??
