Hi Lars and All,

 

Thank you for your answer.

 

I believe that after a thorough Googling and drbd-list search I solved my problem.

 

The issue was related to this:

 

 <http://git.drbd.org/?p=drbd-8.0.git;a=commit;h=b2f332efee55ac248d1c7770b1a4a99e6b3ef879> http://git.drbd.org/?p=drbd-8.0.git;a=commit;h=b2f332efee55ac248d1c7770b1a4a99e6b3ef879

 

After compiling 8.3.0 and installing it, the problem has been resolved.

 

Thank you All for your time.
