In this example, can be worked around by editing the advanced.config to remove the multi-backend section, e.g.

[{riak_kv, [
%%    {add_paths, ["/basho/riak_cs/dev/dev1/lib/riak_cs-2.0.1/ebin"]},
%%    {storage_backend, riak_cs_kv_multi_backend},
%%    {multi_backend_prefix_list, [{<<"0b:">>, be_blocks}]},
%%    {multi_backend_default, be_default},
%%    {multi_backend, [
%%        {be_default, riak_kv_eleveldb_backend, [
%%            {total_leveldb_mem_percent, 30},
%%            {data_root, "/basho/riak/dev/dev1/data/leveldb"}
%%        ]},
%%        {be_blocks, riak_kv_bitcask_backend, [
%%            {data_root, "/basho/riak/dev/dev1/data/bitcask"}
%%        ]}
%%    ]}
]}].

Referenced this issue in the cuttlefish issue tracker as well.

[shino]

This is a bug of cuttlefish. Close.

[binarytemple]

Yes, probably better off being fixed there, I wasn't sure who took responsibility for maintaining the cuttlefish mapping.

[shino]

Understood. It's (almost) riak_cs specific and this issue is nice place to track or not to forget.
