For completeness, one more assertion of lww=false is desirable, isn't it?

add check on lww=false, too. Also, result of riakc_pb_socket:get_bucket_type(Pid, <<"default">>) does not include dvv_enabled explicitly, while HTTP API does. It may be another issue, but any thoughts?

I added following lines to riak.conf and start riak and riak-cs, then got warning about dvv_enabled

[warning] dvv_enabled is strongly recommended to be true (currently undefined)

Configuration is wrong?

I also tested with this config:

buckets.default.allow_mult = true
buckets.default.merge_strategy = 2

My test result: https://gist.github.com/kuenishi/eeb601889e985a6072fb

My conclusion: it's like a Riak bug in PB API.

Found the culprit: https://github.com/basho/riak_pb/blob/develop/src/riak_pb_codec.erl#L241-L299

The decoder ignores dvv_enabled and write_once .

Then, this PR will be deferred to 2.1.1?

Opened basho/riak_pb#127 as a right fix. We'll have to work on workaround, too...

Then, this PR will be deferred to 2.1.1?

If fortunately that is included in Riak 2.1.2, I'd be happy but will push my workaround.

It's better to add white spaces at the end of these two lines because concatenated string is shown in the log.

Dropping this off of 2.1.0 because it's silly to connect to HTTP port just for checking dvv_enabled. Will revive this after basho/riak_pb#127 is merged.

This is on-hold because of riak kv side issue. This is worth to put in future version of riak_cs.
