<div><span>Thanks Digimer for clarifying....</span></div>
<div><br>
<span></span></div>
<div><span>I am trying to create the following setup or rather
will say I have been asked to do so . <br>
</span></div>
<div><br>
<span></span></div>
<div><span>=====</span></div>
<div><font size="2">Cluster Name: ClusterA <br>
<br>
Node1: system1.example.com Priority:1 in Failover Domain<br>
Node2: system2.example.com Priority:2 in Failover Domain<br>
<br>
File System Resource : /data1 - An ext3 file system<br>
<br>
=====</font><br>
<font size="2"><br>
Cluster Name : ClusterB<br>
<br>
Node1: system1.example.com Priority:2 in Failover Domain<br>
Node2: system2.example.com Priority:1 in Failover Domain<br>
<br>
File System Resource : /data2 - An ext3 file system<br>
========================================================<br>
<br>
What I will achieve with this scenario , is that both the
nodes will always be in active mode as one node is having
higher priority in Failover Domain in one cluster and the
other node has higher priority in the other cluster as
shown above. This means that both the file system resource
will always be available in either of the nodes. And if a
node goes down ' suppose system1.example.com ' which is
active in </font><b><font size="2">'ClusterA</font></b><font size="2">' , cluster , the file system resource /data1 on
the cluster will be mounted on system2.example.com which is
already having /data2 mounted on </font><b><font size="2">'ClusterB'
</font></b><br>
<br>
<font size="2">So , based on the above architecture , we are
achieving the following</font><br>
<font size="2">1) Both the mount points will be always
available and </font><br>
<font size="2">2) Both the nodes will be utilized as both the
nodes will be in active mode in either of the cluster .</font></div>
<div><br>
</div>
<div><font size="2">Will be great if you have some inputs to
achieve the same . <br>
</font></div>
<div><br>

<div><font size="2">Thanks</font></div>

> Just one thought: did you intentionally decide against using GFS and
favour ext3?<br>
<br> Nothing intentional here . Was initially trying to check whether it is possible to create two different clusters using same nodes and<br> chosen ext3 for this.<br> Is it not going to be a useful feature if we allow same nodes to be used in different clusters ? <br><br>Thanks<br>Zaman<br> <br><br><br><br><br><br>
