Description tsugano 2016-10-26 01:37:18 UTC
Description of problem:
For an over peta-byte deployment, the product team encouraged us to use the distributed-replicated volume over the dist-dispersed one as they need more rebalance testings with the latter for large-scale deployments. However, we think the dist-dispersed would be best fit for our target use cases, a storage for video streaming, for example.

Version-Release number of selected component (if applicable):

How reproducible:
Configure an over PB volume, extend its size by adding nodes and then trigger rebalance.

Steps to Reproduce:

Actual results:
The distributed-replicated volume is recommended.

Expected results:
We can choose the distributed-dispersed volume as well.

Ben, Ambarish,
     I am aware that one of you are doing the ec perf work with rebalance. Not sure which one it is. Could you take a look at this bug? For now adding needinfo on Ben.

We have done an extensive testing approach to EC with rebalance and other interops too.
below is a testplan on what all were covered
There were a good number of BZs reported ,which are mentioned in the above doc, which are being tracked seperately

Hence moving to verified
