You should be able to do it with shared SCSI, in an active-passive
failover configuration (one system at a time active, the second
system standing by to takeover if the first one fails). Only by
using something like GFS could both be active simultaneously, and
I am not familiar enough with GFS to comment on how reliable it
is. If you get the devices right, you can have a seamless NFS
failover. If you don't, you may have to umount and remount
the file systems to get rid of stale file handle problems.
For SMB, users will have to reconnect in the event of a
server failure, but that is still not bad.
