Subject how to monitor nodetool cleanup?
Date Tue, 07 May 2013 17:43:18 GMT
I'm recovering from a significant failure and so am doing lots of nodetool
move, removetoken, repair and cleanup.

For most of these I can do "nodetool netstats" to monitor progress but it
doesn't show anything for can I monitor the progress of
cleanup?  On a related note: I'm able to stop all client access to the
cluster until things are happy there anything I can do to make
move/repair/cleanup go faster?

FWIW my problems came from trying to move nodes between EC2 availability
zones...which led to
1) killing a node and recreating it in another availability zone
2) new node had different local ip address so cluster thought old node was
just down and we had a new node...

I did the removetoken on the dead node and gave the new node
oldToken-1...but things still got weird and I ended up spending a couple of
days cleaning up (which seems odd for only about 300 gig total data).

Anyway, any suggestions for monitoring / speeding up cleanup would be
