Linux and Unix-Like Red Hat

Hello,

can someone please suggest me in configuring the mysql db on redhat cluster, I have few questions.

  1. where do I have to configure heart beat links, and is there any file in the redhat cluster that we update it to use these ipaddress and these interface on the node.
  2. I am configuring 2-node cluster, active/passive, I have added service group. my question is do I need to configure the failover domain as the 2nd node and assign it to the servicegroup I created. ??
  3. can we configure ext3 on the shared storage, is gfs2 needed ??

Thanks,
