Hi! I have a 16 node cluster with two keyspaces and several column families within each, all with RF=2. All the reads/writes work with all column families but only one of them gives me an unavailable exception, even with CL.ANY consistency. The nodetool ring shows that three of the nodes of the cluster are down (they have their disk full because Cassandra runs out of memory and leaves humongous hprof files).
Anyhow, my question is this - is the unavailable exception being thrown because that particular column family (with its replica) happened to be stored in the three nodes that were down? Is there a way to see what keys/cfs are stored in which node(s) of the cluster? Thanks, Rajat
