Riak Users, A critical bug has been identified in the Riak 1.2 RC2 build that was not in the earlier RC1 build. If you restart an RC2 node, it will overwrite it's ring file with a fresh ring, therefore removing any history that the node was part of an existing cluster. In other words, if you build a cluster of Riak nodes, and then restart a node, that node will no longer be a member of the cluster. Same will happen if you upgrade a node, and then restart it.
Since we know that some users try out RC builds on their staging clusters, and sometimes as 1 or 2 nodes out of many on their production clusters, we wanted to let everyone know about this bug as soon as it was identified. We are going to be pulling the RC2 packages later today. A patch for this bug has been created and is being vetted right now, an RC3 build should land on Monday. If you have run into this issue, you can issue 'riak-admin join -f <node-still-in-cluster>' on the node that believes it is no longer a member of the cluster and the node should re-integrate into the cluster without issue. For the curious, this bug was quickly identified by the testing process we use to qualify RC builds before eventually promoting an RC build to an actual release. It just turns out that our process has always been to publicly release an RC build as soon as it's cut, and then run our QA tests in parallel. Thus, allowing maximum time for both Basho internal testing and testing from the community. Before releasing the first RC (RC1) build, there are multiple internal pre-release builds that are tested using the same process. Unfortunately, this particular regression arose in between RC1 and RC2.
