It look like ggated + geom will do at least part of the job. Setting up

see any way of doing this though. Perhaps I'm missing something.
The exporting the drive via NFS and swopping under haertbeat looks ok
to.
It is just the gom + ggated aspect I am not sure about.
I think ggated and gmirror won't satisfy you because I'd like to call
ggated experimental. Furthermore it is not intended for those tasks,
because it is kept very simple. A better scenario for the current
implementation of ggated is to mount a remote CD filesystem locally.
If you really need DRBD then stay with DRDB and linux.

Thanks,
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.
