</div></div>DRBD can accomplish the data replication in active/active mode utilizing<br>
GFS/OCFS with ease. Read up on DRBD and GFS:<br>
<br>

<br>
If I understand you correctly...<br>
<br>
I suppose a simple way to accomplish this would be to replicate your Xen<br>
DOMU to your secondary node with a slightly different configuration<br>
(ip/hostname/etc.) and utilize the shared storage for user data on both<br>
nodes. This of course would not keep your secondary DOMU's operating<br>
system in sync with the primary.<br>
<br>
Take a look at csync2 to help keep your configuration files up to date<br>
on your Xen DOMU's.<br>

<br>
I'm unclear as to how many physical machines you wish to run this on.<br>
Are you looking to accomplish this task on a total of 2 boxes?<br>
<br>
Cheers,<br>

I want to use the shared storage for public_html for a load balanced
Apache install. You say shared storage, I want to sure, this can be
done with partitions on 2 machine's using drbd and gfs without the need
for a "shared storage" ? I am trying to do this without a san if I
can. <br>
Does drbd have a limit of 2 servers? <div><br>Sorry I sent you this directly on accident Kavan. <br></div>
