nodetool repair will make sure the data is replaced RF times. Run it every RF
nodes around the ring
http://wiki.apache.org/cassandra/Operations#Repairing_missing_or_inconsistent_data
You can also use nodetool cfstats, it will give you some info on the local data
for a node. For example...
Column Family: Article
SSTable count: 4
Space used (live): 1562827944
Space used (total): 1562827944
Number of Keys (estimate): 9980160
…
Compacted row minimum size: 61
Compacted row maximum size: 770
Compacted row mean size: 128
What approach did you take to the bulk load (see
http://www.datastax.com/dev/blog/bulk-loading) ? What numbers are you looking
at and how do they differ from what you would expect to see ?
Cheers
