No. You need a shared filesystem. Which pretty much leaves you on either
NFS or a clustered filesystem. RH has an example of using NFS - with a
strong statement attached that you shouldn't do it that way in real life
because the performance is poor.
Trying to mount ext3 or ext4 simultaneously from two machines (on say
iSCSI) would just result in filesystem corruption.
