I've been lurking on the list for a while now. I'm hoping to use GFS in
a similar situation. 

I have yet to actually setup GFS at all but I what I was hoping to do is
use DRBD and Heartbeat to have a active/passive mirror of the data then
use gnbd on an aliased/takeover IP address to export the GFS file system
to the rest of the cluster.

I have no idea if it will work or not.

I also recall that Philipp has said it wouldn't be that big of a deal to
make DRBD active/active specifically for this situation. Now that GFS is
once again open source there may be more interest in doing the work to
make DRBD active/active. It's been quite a while since I messed with
DRBD but you may want to look into it.
