</div>"I'm glad you asked"<br>
<br>
...because now that you got the stacking going, you *cannot* ever use<br>
drbd0 again! It's your backing device now, please keep that in mind.<br>
It's now off limits in the same way you cannot use the disk partition<br>
underneath drbd.<br>
<br>
What you need to do is create an fs on and mount drbd10.<br>
<br>
Cheers,<br>
