Red Hat Bugzilla – Bug 1388711
Needs more testings of rebalance for the distributed-dispersed volume
Last modified: 2017-03-23 02:14:55 EDT
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): 3.2 How reproducible: Configure an over PB volume, extend its size by adding nodes and then trigger rebalance. Steps to Reproduce: 1. 2. 3. Actual results: The distributed-replicated volume is recommended. Expected results: We can choose the distributed-dispersed volume as well. Additional info:
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 http://etherpad.corp.redhat.com/3-2-ec-rebalance-plan There were a good number of BZs reported ,which are mentioned in the above doc, which are being tracked seperately Hence moving to verified
