I've never taken a snapshot before, so I may be doing something wrong, but I can't seem to take snapshots of my cluster.
It's got 6 nodes, and issuing 'nodetool -h localhost snapshot' or 'nodetool -h localhost snapshot MyKeySpace' seems to work on the first node in the ring, but not on the others.
All processes exit with "Snapshot directory: 1354267525967" etc, but when I try to find the snapshot directory with 'find /path/to/my/cassandra/data/dir -name snapshots' it only finds a directory on the first node, not on any others.
Due to some slightly complicated reasoning, my cluster is running 1.0.11 on nodes 1 and 2, but 1.0.12 on nodes 3-6. I assumed that this would not cause a problem but am trying to upgrade to 1.1.6 on all nodes without losing data, so want to take a snapshot first.
