Re: Re: Riak shuts down itself after couple of minutes

2015-08-07 Thread Cuyler Jones
Hi Hao --

As Alex said, the error you're receiving is generally related to open file
limits set by your OS configuration. Riak requires a large number of
available open files handles. You can find information on how to up your
limits here: http://docs.basho.com/riak/latest/ops/tuning/open-files-limit/

Hope that helps!

Thanks!

Cuyler

 Hi Hao,

 Looks like you might be running into an EMFILE error:
 http://docs.basho.com/riak/latest/community/faqs/logs/#riak-logs-contain-error-emfile-in-the-message

 What’s the open files limit on your nodes?

 Thanks,
 Alex

 I am running it on a single node.

 Using Erlang riak client. I added a map bucket type, create a new index,
 set the index on a bucket, saved a few map data into the bucket. Then I did
 some search. All good. Then I can remember I tried a invalid search query
 like title_s_register:[New movie one] which shuts down Riak. But it may
 or may not be the first time Riak starts to shut down. I can't remember.

 Now Riak itself shut down after running a few minutes.  I must have done
 something really wrong. Any idea what I can do? I have tired to restore
 bitcask data folder from a backup from days ago. It didn't help. It still
 crashes.

 The console.log is here : http://www.pastebin.ca/3092510
 The error begins at Line 172

 Anyone can help? Much appreciated.

Re: is it possible to start riak_kv as foreground process?

Hi Roman --

If riak is not currently running:

bin/riak console

If riak is currently running:

bin/riak attach

 hello,

 is there any way to start RIAK_KV as a foreground process instead of as a
 demon process, which is what bin/riak start” does?
