Yes, we are aware of this issue and have prepared a solution to it<br>
internally. It only affects kernels in the 4.8 and 4.9 series.<br>
Unfortunately, this includes Debian 9. It was caused by the change in<br>
the way we deal with compatibility for older kernels. You should see a<br>
9.0.21 release soon which will fix the issue.<br>
<br>
I have pushed the fixed version to this temporary branch:<br>
<a href="https://github.com/LINBIT/drbd/tree/drbd-9.0-debian9" rel="noreferrer noreferrer" target="_blank">https://github.com/LINBIT/drbd/tree/drbd-9.0-debian9</a><br>
This is the main fix for the issue:<br>
<a href="https://github.com/LINBIT/drbd/commit/15cf0b73971842a7bc8fe6d5217a8f79c5babf80" rel="noreferrer noreferrer" target="_blank">https://github.com/LINBIT/drbd/commit/15cf0b73971842a7bc8fe6d5217a8f79c5babf80</a><br>
If you are able to build from this branch then you are very welcome to<br>
use it. We welcome any feedback if you do try it.<br>
<br>
Otherwise you can downgrade back to 9.0.19.<br>
<br>
Best regards,<br>
Joel<br>
