          aha, parallel-scale test compilebench hung in manual run, the MDS is being rebooted
          more logs occurr
          ok, Chris, TT-851 is not a test environment issue, it's a Lustre issue, I'll gather logs, file new ticket and update TT-851
          thank you, Chris

          Oleg, Bobi, do you have any ideas about whether the above MDS reboot issue is a Lustre issue or test environment issue? Thanks.
          This is really blocking the Lustre b2_3 testing now.

          Lustre Build: http://build.whamcloud.com/job/lustre-b2_3/17

          The issue still exists:

          BTW, all of the syslogs in the above reports are empty. I checked the syslogs from brent node but still found nothing useful for debugging.

          However, comparing to the results on b2_3 build #16, although performance-saniy test_3 and sanity test_32n also hit MDS reboot issue, there are error messages on the MDS console logs on build #17 (no such messages on build #16), please refer to LU-1906, LU-1909 and LU-1863.

          So, I'm not sure whether the above parallel-scale* and large-scale failures were caused by Lustre issues or not although there were no specific error messages on their logs.

          BTW, autotest did not gather syslogs for the above reports, I had to find out the syslogs on brent:/scratch/logs/syslog.

          Hi Chris,
          Please take a look at my above comments on the syslog of performance-sanity: https://maloo.whamcloud.com/test_sets/7c320096-fa73-11e1-887d-52540035b04c, the MDS (client-30vm3) was rebooted before timeout.

          The failures are real timeouts is my point. The reboot happens after the test has timed out.

          and we do capture the logs, autotest was restarted because it had stopped capturing logs.

          same with the other failures this morning, I can't see why the previous did not have the LBUG but I can see any that replicate it.

          The two conf-sanity failures are caused by http://review.whamcloud.com/#change,3671 and http://review.whamcloud.com/#change,3670, which are still under development.

          The failure instances I reported in this ticket are on the main b2_3 branch. There is no such LBUG.

          we need collect all relevent logs before rebooting the node. Or else we know nothing about the issue.

          An issue did exist for a short while where the console log was not being shut before the report. This lead to the reboot appearing in the test log when the test was being correctly timedout.

          I'm closing this issue as this is I beleive not resolved.
