I did restart the cluster and now it is normal 5GB.

I also have this problem. My data on nodes grows to roughly 30GB. After a
restart only 5GB remains. Is a factor 6 common for Cassandra?

Good idea Jeremiah, are you using compression Michael ? 

 

Scanning through the CF stats this jumps out.

 

                Column Family: Attractions

                SSTable count: 3

                Space used (live): 27542876685

                Space used (total): 1213220387

Thats 25Gb of live data but only 1.3GB total. 

 

Otherwise want to see if a restart fixes it :) Would be interesting to know
if it's wrong from the start or drifts during streaming or compaction. 

 

Cheers

There were some nodetool ring load reporting issues with early version of
1.0.X don't remember when they were fixed, but that could be your issue.
Are you using compressed column families, a lot of the issues were with
those.
Might update to 1.0.7.

Hi,

I have finished running repair on all 4 nodes.

 

I have less then 10 GB on the /var/lib/cassandra/data/ folders

 

My question is Why nodetool reports almost 50 GB on each node?

 

Thanks

Michael
