I'm new in elasticsearch and rally. Now I'm trying "Benchmarking an existing cluster" as below.  
[https://esrally.readthedocs.io/en/1.0.1/recipes.html#benchmarking-an-existing-cluster](https://esrally.readthedocs.io/en/1.0.1/recipes.html#benchmarking-an-existing-cluster)

After the following command line was executed, I faced error.  
Would you please tell me how to resolve it?

$ esrally --track=pmc --target-hosts=ip\_address:9200,ip\_address:9200,ip\_address:9200 --pipeline=benchmark-only

It seems like you have run out of disk space? Rally downloads and uncompresses data files that can be quite large, so check in the track how large these are before starting so you have enough space available.

Hi Christian,  
Thank you for your prompt reply.  
After I prepared enough disk space, the race succeeded.
