Hi,<br>
<br>
Great! Nice to hear that the problem area is found. Can I download
the updated source? Or can you provide me with the patch on the
source file? Then I'm able to test it.<br>
<br>
Regards,<br>
Rob van der Wal<br>

This message indicates that mounting with DAX is failing here:

But DRBD performs the corresponding check here:

Hm.
Unfortunately ((unsigned long)-ENOTSUP < 1) is false,
we simply did not notice error returns :-(
Fixed now.
Still, a block device claiming to support it,
but then returning "sorry, not supported"
once you actually try to use it, is ... not very friendly either.
