What tool are you using to create buckets? If you can provide debug output, it looks as though the message sent to Riak CS is bad ("error, malformed_xml") -- Luke Bakken Engineer lbak...@basho.com On Sat, Jul 9, 2016 at 1:11 AM, s251251251 wrote: > Hello > after some day after riak-cs Installa

Re: Riak on Solaris/OmniOS/illumos

2016-07-12 Thread Luke Bakken
Hi Henrik, Sorry for the delay in responding to you via this channel. Solaris / Illumos support will be dropped in a future Riak release, as will FreeBSD. However, this does not preclude the community continuing support for these platforms. All the necessary code to build platform-specific Riak pa

Recovering Riak data if it can no longer load in memory

Whilst load testing the platform (by creating 0.5 million ejabberd users via Tsung), I found that the Riak nodes suddenly crashed. My question is how do we recove

It would be helpful if you described the physical characteristics of the servers: memory size, logical cpu count, etc. Google created leveldb to be highly reliable in the face of crashes. If it is not restarting, that suggests to me that you have a low memory condition that is not able to loa

Thanks much Matthew. Yes the server is low-memory given only development right now - I'm using an AWS micro instance, so 1 GB RAM and 1 vCPU. Thanks for the tip - let me try move the manifest file to a larger instance and see how that works. More than reducing the memory footprint in dev, my conce

You can further reduce memory used by leveldb with the following setting in riak.conf: leveldb.threads = 5 The value "5" needs to be a prime number. The system defaults to 71. Many Linux implementations will allocate 8Mbytes per thread for stack. So bunches of threads lead to bunches of
