<div class="im">> It just replicates whatever you write to it, no more, no less.<br>
<br>
</div>That's why I don't understand why it works fine when LVM clients are<br>
connected on the same DRBD server, and it doesn't work when each<br>
client is on separate DRBD server (despite replication is working).<br>
Can you explain this behaviour ?<br>
<br>
Furthermore, I do some tests with cLVM. My cluster is working, I can<br>
create pv and vg on one node, but the other can't see it. Then, when I<br>
try to create a LV, cLVM says :<br>
lvcreate -L82M -n testvol vg_xen<br>

Sorry if I miss someting...<br></blockquote></div><br>Just a note from a clvmd point of view.<br>There are some modifications to make to /etc/lvm/lvm.conf for clvmd.<br>I thinks this one can be a good starting point in general, also if you prefer to use HA-LVM instead of CLVMD (discard please if you already set up it correctly):<br>
