Riak S2 error

[Michael Walsh]

All,

I'm trying to set up a RIak S2 instance to integrate with KV and I'm
getting the following cuttlefish error out of advanced.config. Any
suggestions on where I'm going wrong?

notes: erlang error was fixed. All paths are correct.

Thanks!

Re: Riak S2 error

That definitely fixed the configuration problem, but now its tossing a
riak_cs_kv_multi_backend is non-loadable. So I'll dig into riak_cs some
more to try to see what could be wrong there, although it is not reporting
any errors while running.

That was the first thing I checked. Good thought though.

riak-cs sizeing suggestions

[Michael Walsh]

There is a nice BitCask formula for creating suggested nodes for a riak-kv
ring. Is there something similar for riak-cs? What are the rules around how
large the key store needs to be in the multi-tenant data store, as I assume
cs is only storing a reference to the large object value. Are there any
guidelines around cs node sizing?
