This whole thread has been fascinating. I really wish we (OI) had the
two following things that freebsd supports:
1. HAST - provides a block-level driver that mirrors a local disk to a
network "disk" presenting the result as a block device using the GEOM API.
I have a prototype with two freebsd VMs where I can failover back and
forth and it works beautifully. Block level replication using all open
source software. There were some glitches involving boot and shutdown
(dependencies that are not set up properly), but I think if there was
enough love in the freebsd community that could be fixed. I could be
wrong, but it doesn't *seem* as if either HAST (or an equivalent) or
CARP exist in the OI (or other *solaris derivatives) space. Shame if so...
