I count the disk usage. I found that from nodetool information, space used (live) is about the nodetool ring info.
We are testing the the performance of Cassandra for Big Data. Now I also have the problem. From nodetool cfstats, the space used (live) is 7 times than the Space used (total). Why?thx

I am testing the TTL with loading 400G.When all the data are expired, I waited for some hours.Later, the nodetool ring is still have 90GB. So I made a major compaction.Then there are 30GB from the nodetool ring. After I saw the file system,I found there are zero sstable.I don't know where comes the 30GB?
