we'd like to create a two-node cluster for our services (web, database, virtual machines). We will have two servers and a shared fiberchannel SAN. What would you do e.g. with the content of the webpages we offer ? Put them on the SAN so we don't need to synchronize them between the two nodes ? Also the database and the vm's on the SAN ? Which fs would you recommend for the SAN volumes ? OCFS2 ? Can I mount the same volume on each node contemporarily ? Or do I have to use the ocfs2 as a resource managed by pacemaker, so that the volume is only mounted if it is necessary ?

Thanks for any hint.
