Hi Zack, I was testing on some home-made Teuthology cluster. Till now I can use the teuthology-suite to submit the test cases and start some workers to do the tests. From the Pulpito logs I can see most of the tests are passed except there was some error when aggregating the results in the last step. The error message was like: "2015-06-24 08:41:33.334317 mon.1 192.168.13.117:6789/0 4 : cluster [WRN] message from mon.0 was stamped 0.709253s in the future, clocks not synchronized" in cluster log This was due to the time lag between monitors to my knowledge. I checked the clock settings in Teuthology and find the NTP server are defined in ceph-qa-chef/cookbooks/ceph-qa/files/default/ntp.conf. Is there any other settings on the clock side there?
