</div>as long as you don't have pre-existing data,<br>
and you do the mkfs on /dev/drbd,<br>
that is all fine, and you just cannot get it wrong.<br>
<br>
if there _is_ pre-existing data, or you use some other tools to resize<br>
partitions and file systems, and you use drbd internal meta data, you<br>
have to be careful.<br>
<br>
but yes, we'll have to write some "Again, on the commandline ..."<br>
for drbd 8 somewhen.<br>
