Thanks Dan.
But I’m trying to convert my Bitcask nodes to LevelDB nodes. I thought I could just stop the node, change the backend in app.config, restart, and join to a Bitcask node. The data would transfer to the empty LevelDB node and I could roll to the next nodes. If the ring_num_partitions was 256 under Bitcask backend, shouldn’t it continue to be 256 under LevelDB if ring_creation_size is 256 in app.config?

Assuming the LevelDB node is empty, you can do the following: 1. Stop the node 2. Clear out the data directories (data/ring, data/leveldb, data/bitcask, data/mr_queue, data/kv_vnode) 3. Verify "ring_creation_size" is set to 256 in the app.config file 4. Start the node 5. Verify "ring_num_partitions" in "riak-admin status" is 256 6. Join the node to the cluster Thanks, Dan Daniel Reverri Developer Advocate Basho Technologies, Inc. d...@basho.com On Fri, Oct 21, 2011 at 9:30 AM, <jim.ad...@comcast.net> wrote: 64 on the LevelDB vs 256 on the Bitcask.

Thanks, Dan Daniel Reverri Developer Advocate Basho Technologies, Inc. d...@basho.com 2011/10/20 Jim Adler <jad...@intelius.com> I tried the Bitcask-to-LevelDB procedure on 1.0.1 to switch my backend from Bitcask to LevelDB. I have one node on Bitcask with my data and the other node with a fresh LevelDB backend. When I join the fresh LevelDB node, I get the following error: Failed: r...@xx.xx.xx.xx has a different ring_creation_size riak-admin status | grep creation gives: ring_creation_size : 256 Any ideas?

Cc: riak-users Subject: Re: Riak 1.0 There are instructions on the wiki: http://wiki.basho.com/Secondary-Indexes.html#Migrating-an-Existing-Cluster-(Method-One) Basically, you will have each node leave the cluster, switch the backend, and then rejoin. The process is something like this: 1) Issue `riak-admin leave` and wait for all transfers to complete 2) `riak stop` 3) Change the backend to the `riak_kv_eleveldb_backend` 4) `riak start` and `riak-admin join <a_node>` 5) Repeat for each node in the cluster Ian Plosker Developer Advocate Basho Technologies On Sep 30, 2011, at 10:41 PM, 54chen wrote: Congratulations!
