Hi Hristo, Please see my comments and questions inline...

Could you please try and delete the keys using "curl -vvv -XDELETE http://...."; and let us know the output? The "-vvv" argument will give us the HTTP response code and will show all headers. > When I list the keys for a bucket, it shows me > the old keys, however if I try to retrieve the data associated with a key, > no data is found. Could you also paste the output when you retrieve a "deleted" key via "curl -vvv -XGET http://...."; ? > Is there a way to wipe the keys in the bucket so it starts from a clean > slate?

Don't delete everything from /var/lib - you'll delete the ring and other important directories. Find the value of data_root for your data backends, and then delete the contents of that directory. For instance, /var/lib/riak/bitcask is the default data_root for bitcask, so to delete all the data you'd execute the following on all hosts: riak stop rm -rf /var/lib/riak/bitcask/* riak start > I also noticed that recently I did an update, and one of my clusters was > using leveldb as a backend and another was using bitcask.

Is it safe to delete it? Yes if you are sure the data is no longer needed. -- Luke Bakken Engineer / CSE [email protected] _______________________________________________ riak-users mailing list [email protected] http://lists.basho.com/mailman/listinfo/riak-users_lists.basho.com
