Thanks again guys, this has been a major blocker for us and I think we've
made some major progress with your advice.
We have gone ahead with Lerh's suggestion and the cluster is operating much
more smoothly while the new node compacts. We read at quorum, so in the

Hi Paul,
Agh, I don't have any experience with sstableofflinerelevel. Maybe Kurt
does, sorry.
Also, if it wasn't obvious, to add back the node to the cluster once it is
done would be the 3 commands, with enable substituted for disable. It feels
like it will take some time to get through all the c

Thanks for the responses Lerh and Kurt!
Lerh - We had been considering those particular nodetool commands but were
hesitant to perform them on a production node without either testing
adequately in a dev environment or getting some feedback from someone who
knew what they were doing (such as yours
What version are you using? There are improvements to streaming with LCS in
2.2.
Also, are you unthrottling compaction throughput while the node is
bootstrapping?
Hi Paul,
The new node will certainly have a lot of compactions to deal with being
LCS. Have you tried performing the following on the new node once it has
joined?
*nodetool disablebinary && nodetool disablethrift && nodetooldisablegossip*
This will disconnect Cassandra from the cluster, but not
Hi,
We run 48 node cluster that stores counts in wide rows. Each node is using
roughly 1TB space on a 2TB EBS gp2 drive for data directory and
LeveledCompactionStrategy. We have been trying to bootstrap new nodes that
use a raid0 configuration over 2 1TB EBS drives to increase I/O throughput
