Hi Henrik, It seems http proxy option[1] is needed to specify your Riak CS node instead of the endpoint option. Could you try to use it? Although you might already know, there is a good docs[2] which explains how Riak CS can interact with S3 clients. [1]: http://docs.aws.amazon.com/aws-sdk-php/v

2015-08-06 Thread Matthew Von-Maszewski
Two ideas about lots of cpu with nothing happening: - is Riak entropy setting "active". Weekly it will rebuild hash trees - does this activity occur after a handoff? Sometimes leveldb needs time to catch up afterward in current releases (fix coming soon). Matthew Sent from my iPad > On Au

Thanks Magnus & John. Yes certainly I will test it on a separate cluster first! Which is related to another question I have. If I want to backup I can archive the directories on the nodes as described here: http://docs.basho.com/riak/latest/ops/running/backups/#OS-Specific-Directory-Locations Bu

Sujay, You're right - the best way to verify the backup is to bring up a separate 5 node cluster, and restore it from the backup files. The procedure is slightly more involved than untar-ing, though. The backed up ring directories from the original cluster will contain the node ids (which rely on

Because it's important to note, the version of Riak is 2.0.5. AAE was actually the first thing I checked - it was on, but turning it off had no impact. Interestingly enough, I was able to pinpoint the source of the higher than expected CPU to a service that was frequently polling a set of map and

Fwd: why leaving riak cluster so slowly and how to accelerate the speed

2015-08-06 Thread Changmao.Wang
Hi Raik user group, I'm using riak and riak-cs 1.4.2. Last weekend, I added four nodes to cluster with 5 nodes. However, it's failed with one of disks 100% full. As you know bitcask storage engine can not support multifolders. After that, I restarted the "riak" and leave the cluster with th

Hi Amao, Can you explain a bit more which steps you've taken, and what the problem is? Which nodes have been added, and which nodes are leaving the cluster? On Tue, Jul 28, 2015 at 11:03 PM, Changmao.Wang wrote: > Hi Raik user group, > > I'm using riak and riak-cs 1.4.2. Last weekend, I added

Hi, It’s a long story. The short answer is: you can’t with that client, it has strong opinions so the best thing to do is this: have your app interpret the absence of a flag as false (the bottom/default value for a flag.) The long story: the semantic for the flag is “observed remove” or “add-wi
