Download link for basho-bench tool

helsing
Hi,

In the Benchmarking docs on the basho homepage (http://docs.basho.com/riak/kv/2.2.3/using/performance/benchmarking/) there is a reference to download rpms (i.e http://ps-tools.s3.amazonaws.com/basho-bench-0.10.0.53.g0e15158-1.el7.centos.x86_64.rpm)
However this link is not accessible.

Where can I find downloadable binaries nowadays?

Cheers

Hi Patrik,


I do not have admin rights to the Amazon S3 buckets, and am not in a position to establish alternative download locations.

HTH.

Magnus

Hi all,

My impression of Riak has always been that it would recover from anything but yesterday we had the worst happened, there was a power outage so all the servers in a Riak cluster went down, once they were back we have been having these constant so my questions are:
  • How can I recover from this?
  • Isn't Riak supposed to restore corrupted hashes from other nodes?

This is not our production cluster but our development is now stuck because all the data we had there would take days to restore from another cluster, I hope there is a solvable problem.

Regards,

Guido.

Re: Riak issue after power outage

Fred Dushin-2
There may be better ways, but what I would do is:

Stop Riak, blow away your ${platform_data_dir}/anti_entropy directory (and yz_anti_entropy, if you have search enabled), and restart.  This will force a rebuild of your hash trees.  They rebuild automatically anyway; this is just making them rebuild faster.

So it would recover .. eventually.
