I would like to know the feasibility of use of the following and any gotchas, constraints, risks for the same.

In a Oracle clusterware (now called grid infrastructure) cluster nodes (2 nodes cluster) on Linux - configured in Active-Passive mode (Only one node will run a given cluster resource/service at a time) -
Can I use a LUN presented to both the nodes, format it as ext3 filesystem and use in the cluster to mount it to one server only at a time?
[I wont be using cluster LVM - just format the LUN as a single partition as ext3 filesystem and mount on one server. Ensuring that the filesystem is mounted only on one server at any given point in time (through the scripts for defining cluster resource).]

Is this a well used approach?
Is this an acceptable approach?
Are their any issues, risks in this approach?

Thanks.
