Hi,
we changed the n_val of a bucket from 3 to 12. If we are now doing this:
riak:8098/riak/config?keys=true
or
riak:8098/buckets/config/keys?keys=true
we get some keys multiple times. Getting the content works
well but we can't rely on the output (or have to sort/uniq the output).

Hi,
we have suddenly (regarding to riak stats) really big objects (100th
percentile of object size) of 400MB to 900MB.
We have no clue from where or how this could be.. is it somehow
possible to identify them easily?

Hi @list,
I'm trying to upgrade our Riak cluster from 1.3.1 to 1.4.2 .. after
upgrading the first node (out of 12) this node seems to do many merges.
the sst_* directories changes in size "rapidly" and the node is having
a disk utilization of 100% all the time.
I know that there is something like

Hi,
I think the only "save" way is to fetch a key out of a bucket. Otherwise
a fresh reinstalled node with a fresh installed riak without any data
would accept _writes_ to it even before it is in the cluster.
So I would always do the "fetch key" check. (The backend has to be up as
well for that,
