I've got some nodes in a moving state in a cluster (the nodes to which
they stream shouldn't overlap), and I'm finding it difficult to determine
if they're actually doing anything related to the move at this point, or if
they're stuck in the state and not actually doing anything.
In each case, I
Hi.
We've been running a 7-node cluster with RF 3, QUORUM reads/writes in our
production environment for a few months. It's been consistently stable
during this period, particularly once we got out maintenance strategy fully
worked out (per node, one repair a week, one major compaction a week,
to.

After further review, I'm definitely going to scrub all the original
nodes
in the cluster.
We've lost some data as a result of this situation. It can be restored,
but
the question is what to do with the problematic new node
that gets us. Thanks for the assistance.

The outcome of the analytical jobs run overnight while some

Now that I've said all that, something will inevitably go wrong, but until
that happens, thanks again for the feedback.

Is there any straightforward means of seeing what's going on after issuing a
truncate (on 0.7.5)? I'm not seeing evidence that anything actually
happened. I've disabled read repair on the column family in question and
don't have anything actively reading/writing at present, apart from my
one-off
I got from the docs but it wasn't totally clear to me.

I'll defer to the Rackspace folks regarding Rackspace Cloud; it has been
I/O on average since you're dealing with a real, local disk. But I
don't know about getting a second disk in that environment, though.
