<br>
And a little addition:<br>
<br>
I created a 3 32GB disks for a KVM-Guest on that SATA-Disk:<br>
<br>
First on local LVM, second on DRBD using external metadata and third on<br>
DRBD using internal metadata.<br>
<br>
Each of that 32GB disks was partitioned to one 32GB partition and was<br>
formatted inside the KVM-Guest (Debian Squeeze, disks connected as<br>
virtio-device) with ext3.<br>
<br>
The formatting took 19s for local lvm, 95s for drbd with external<br>
metadata and 133s for drbd with internal metadata...<br>
<br>
