Re: Multiple nodes leaving cluster

2017-02-08 Thread Shaun McVey
Hi Daniel, It should be safe, yes. If you run the `cluster leave` commands, then run `cluster plan` (but don't yet run `cluster commit`), the output will show if there's any violations in spreading each of your 3 copies around the cluster. If it does provide a warning, you can `cluster clear` an

Hi Steven, Based on that log output, it looks like you're running into issues with system limits, probably open file limits. You can check the value that Riak has available by connecting to one of the nodes with riak attach, then executing: ``` os:cmd("ulimit -n"). ``` (After, disconnect with c

Re: Question about claimant node.

2017-01-18 Thread Shaun McVey
Hi Alex, The claimant node is used in operations related to adding/removing nodes from the cluster, things like that. If the node dies, for example, due to hardware failure, then the cluster will still continue to operate normally. In this regard, there's nothing special about the claimant node.

Hi Neo, 1) When building from source, the version numbers never show. They only appear in the packaged versions. That's why you're not seeing them. 2) After creating the admin user - did you change anonymous_user_creation back to 'off'? 3) I'm not entirely clear on what you did there - did you
