Flush Commit Log
Dear all,
How can I flush all Commit Log for Cassandra version 042?
I use nodeprobe flush but It seem does not run.
Thank a lot for support.

Yes, no problem with my live Cassandra server.
Thanks, Jonathan.

Sounds like flush generates a lot of i/o. Not surprising.

Thanks Jonathan,
When I run "nodeprobe flush" with parameter -host is Cassandra server setup
on my computer, my computer is hang up by Cassandra. (When I kill all Java
process, the computer will work well)
Yesterday, when run "nodeprobe flush" on my live server, I didn't flush all
keyspace so that commit log files weren't deleted. Today, after flush for
all keyspace, commit log files were deleted

You'll have to give a more detailed error. "nodeprobe flush" is
exactly what you should be trying.
