Subject Best strategy for adding new nodes to the cluster
Date Mon, 27 Sep 2010 13:46:13 GMT
Hi All,

We're currently running a cassandra cluster with Replication Factor 3,
consisting of 4 nodes.

The current situation is:

- The nodes are all identical (AWS small instances)
- Data directory is in the partition (/mnt) which has 150G capacity and each
node has around 90 GB load, so 60 G free space per node is left.

So adding a new node to the cluster will seem to cause problems for us. I
think the node which will stream the data to the new bootstrapping node,
will not have enough disk space for anticompacting its data.

What should be the best practice for such scenarios?
