In <a href="https://build.gluster.org/job/distributed-regression/264/console" rel="noreferrer" target="_blank">https://build.gluster.org/job/distributed-regression/264/console</a> I see this test case is failed and re-attempted. But I couldn't find logs.<br>
There's a link in the end of console output where you can look for the<br>
logs of failed tests.<br>
We had a bug in the setup and the logs were not getting saved. We've<br>
fixed this and future jobs should have the logs at the log collector's<br>
link show up in the console output.<br>

I know the geo-rep ones are easy to fix. The playbook for setting up geo-rep correctly just didn't make it over to the playbook used for these images.<br>

There are a couple of intermittent memory issues with the test script that we need to debug and fix before I'm comfortable in making this job a voting job. We've worked around these problems right now. It still pops up now and again. The fact that things break often is not an excuse to prevent avoidable failures. The one month timeline was taken with all these factors into consideration. The 2-week timeline is a no-go at this point.<br>
