Joe, Are there any error messages in the leveldb LOG and/or LOG.old files? These files are located within each vnode's directory, likely /var/lib/riak/data/leveldb/*/LOG* on your machine.
The LOG files are not to be confused with 000xxx.log files. The lower case *.log files are the recovery files that should contain the keys you are missing. If they are not loading properly, the LOG files should have clues.
