If I assume Space used (total) is in byte the sum is coming to about 32 GB which is not the space taken by data_file_directories. Some one can help to know how much space is used by each CF's ?

Regards, abhinav --00235440bca30cc378049bd43f2a Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable I am using 4 column family in my application , the result of=A0cfstats for = space taken by different CF are as below-
