Hi Michael,<br>
<br>
I do this all the time when replacing a cluster.<br>
Haha, I am a little surprised you ask this, as you are one of my hero's
here ;-)<br>
You know that before DRBD completes its sync, you already can use its
primary...<br>
So what made you to be unsure about this ?<br>
<br>
Freundliche grüssen / Kind regards,<br>

<pre wrap="">Yes this is doable.
One method would be install DRBD, setup your config and resources as
normal, including making your new server primary, then leave it in an
unconnected state. You can copy data to it at this point.
Once you have your secondary server up and running then make the
necessary changes to your DRBD config, copy it to the secondary server,
reload DRBD on your primary, load it on your secondary and tell it to
connect.
HTH,
Brian

<pre wrap="">Hi,
I need to migrate two independent servers into a XEN/DRBD-setup with
two machines. For this reason I want to
-- build a new machine,
-- set it up to replace the first server,
-- move the first server on the new machine
-- then move the second server temporarily as a XEN-instance onto the
first server and then
-- replace the second server with a new machine and
-- move the temporary second server on its own machine.
The idea is to be able to move both servers on one machine if the
other breaks.
The problem is that I would like to prepare the first machine with DRBD
before I have the second node available.
Playing around for two days show that there seems to be no way to set
up a system that way.
I was searching this list, various howtos and google without much
success.
Two questions:
-- Does this work at all?
-- Is there any reasonble Howto?
best regards
