[Drbd-dev] [CASE 12] 2 primary split-brain is not detected

[Philipp Reisner]

Hi,

I am following up on CASE 12 now.

I was not able to reproduce what you describe in this report.
Please check that you can still reproduce it with current GIT-head.
If yes, please re-send it with a more detailed description, including:

 Configuration used.
 Logfiles from begin to end of the test.

Thanks!

Best regards,
 Phil
