So, in single-primary mode and using ext3 fs type, a node can have the<br>
role of primary for 2 resources without any problems.<br>

<br></div>
one node can be primary for any number of drbd resources that are<br>
configured for this host, as long as no other host is currently in<br>
primary mode and no split brain has occured.<br>
<br>
in case of a "split brain", there is no connection between the<br>
hosts running drbd and thus both nodes could end up as primary hosts.<br>
<br>
e.g. both are secondary and uptodate, you unplug the network connection<br>
and promote both to primary.<br>
<br>
thats why it is important to address split brain scenarios.<br>
(the manual should provide information on this)<br>
