I have a setup using heartbeat and Freebsd which uses rsync to keep the
drives in step. The only problem is that rsynce is run as a cron job which
makes balancing the Cron Invervals with the run time of rsync a bit hit
and miss.

Having read up more on ggated, I may try it on some spare machines and
drives I have lying around. I take your point about it being expermential
though but as I see it it is about the only thing I need that FreeBSD is
week on. ISTR GEOM Started that way too. Perhaps it is something I can
help FreeBSD with so I can give something back.
