Has anyone used GFS with cyrus? Could one theoretically create a
redundant, loadbalancing cluster using two boxes, GFS and a SAN?

Well, I did not consider that option since the SAN become a single
point-of-failure, and that is a big no-no according to the
specifications I have at the moment.
If it would have been possible, it would have been my first choice
though.
Do you consider the SAN a SPOF even if you have multiple paths to it
from each server and it has no internal SPOF? If so, isn't your
cluster or your single physical location a SPOF?
Two location, a single path (20 Mb/s) between the two. Thinking about
it, the SPOF is actually the link between the two location. The
situation is pretty much toasted as there cannot be a fully redundant
setup. Case closed !
On a similar note, RedHat have apparently bought Sistina, and GPLed
GFS. This is great news for HA under Linux, IMHO. I will be testing
it soon.
