iSCSI + sw raid will probably let you do this. Otherwise, maybe, but I
suspect you'd be in for a rather harsh time of it. No matter how you do
it, expect it to be slooooow, and expect to be in for some
mind-bogglingly slow and bandwidth gobbling rebuilds whenever a
connection goes down for long.

I'd be looking at a higher level scheme instead, such as a replicating
file system, database replication, etc as appropriate for the
application.
