That largely depends on what exactly you want to do.
You could export storage space via iSCSI and apply CLVM on top of that.
IIRC CLVM can now handle mirroring.
It's nowhere nearly as good as DRBD, though - that provides a very
comprehensive solution for most eventualities you might face, including
Why, exactly, would you want to limit yourself to only what is in the
distro? DRBD builds cleanly into RPM packages, I use it on a number of
systems with GFS on top.
