there was a nasty bug in the peer outdater in 8.3.10 - I am not sure
if it hits you in dual primary, but it hit us pretty hard on one of our
test systems in an active/passive configuration.<br>

<br><tt><font size=2>I just started playing around with drbd, so sorry
if I'm still not<br>
familiar with concepts and tools of drbd.<br>
<br>
After installation of the first pair of servers in primary-primary-mode<br>
it worked immediately without problems. I now want to set up another pair
of<br>
servers. OS is Debian-Lenny (Proxmox).<br>
<br>
But there two differences:<br>
- local storage for drbd-device is md (= Linux soft-RAID) with RAID-0<br>
- Initially there is only one server available; the other should be<br>
added if the first one is running.<br>
<br>
<br>
Meanwhile there is a device /dev/drbd1 and "drbdadm up r1" can
be run<br>
without error messages, but the device isn't available for tools like<br>
parted or pvcreate:<br>
<br>
pve-153:~# parted /dev/drbd1<br>
Error: Error opening /dev/drbd1: Falscher Medien-Typ<br>
( = incorrect media type ?)<br>
<br>
pve-153:~# pvcreate /dev/drbd1<br>
Device /dev/drbd1 not found (or ignored by filtering).<br>
<br>
drbd-version is 8.3.10<br>
