Hi Daniel,

Please let me know if all nodes in this cluster were set up completely
fresh, with empty backend directories, or if any of them had been used
before for a Riak installation. If the latter is the case, it may be that
the key in question had already been used once before. Cluster nodes pick
up data from pre-existing backends.

How do you access the key for read and write operations?

Kind Regards,
