[Linux-cluster] About Linux Cluster

[Tom Stars]

Hi

I am newbie to  linux clusters. i would like to setup a linux cluster of 4
nodes, and a DAS box for Storage connected to
linux systems.through an optical fiber. All linux systems are running RHEL
4.0. AS
Q1)Do i need GFS to be configured in case i have to run oracle on the
cluster nodes . (Oracle 11i Application Server)
Q2) when do i need GFS.
Q3) If the DAS is mounted on 1 node and create an NFS Server and provides
shares to other nodes, does it affect the performance.

Thanks.
Tom.
