When you look in the logs please let me know if you see this error… https://issues.apache.org/jira/browse/CASSANDRA-4223
I look at nodetool compactionstats (for the Merkle tree phase), nodetool netstats for the streaming, and this to check for streaming progress: while true; do date; diff <(nodetool -h localhost netstats) <(sleep 5 && nodetool -h localhost netstats); done Or use Data Stax Ops Centre where possible http://www.datastax.com/products/opscenter Cheers ----------------- Aaron Morton Freelance Developer @aaronmorton http://www.thelastpickle.com On 8/05/2012, at 2:15 PM, Ben Coverston wrote: > Check the log files for warnings or errors.
