After bumping REX-Ray from v0.9.0 to v0.11.2 for https://jira.mesosphere.com/browse/DCOS_OSS-2245 we observed that the incidence of test flakiness increased.
We later dropped back to v0.9.0 to back out of the test failures in https://jira.mesosphere.com/browse/DCOS_OSS-2310.
We decided to triage these failures in https://jira.mesosphere.com/browse/DCOS-37441 and determined that upgrading to v0.11.1 while setting the DCOS_LEGACY=true flag to opt out of the new CSI logic appeared to introduce no new flakiness.
This issue tracks the task of bumping REX-Ray to v0.11.1 in DC/OS 1.10, 1.11 and master.
EDIT: Let's bump to 0.11.2. The only difference is a rename of 'thecodeteam' github org to 'rexray'.
