Doing something like this w/o having servers participate in some sort of
locking or journaling scheme is somewhat scary. You'd have to be pretty
careful on how you access a shared physical storage system in this
I believe Sistina's GFS project might be more to your liking. IIRC, it's
a clustered, journaling filesystem designed explicitly for your setup.
It's a bonus that it is also GPL. Check it out at:
http://www.sistina.com/products_gfs.htm. The latest GPL version of GFS
seems to be 4.1.1 (as present on ftp://ftp.sistina.com/pub/GFS). I'm
not sure, but I'm assuming from the info available on the website that
GFS 5.0.1 is commercially available as well. Is Sistina doing something
similar to TrollTech w/licensing GFS, then? Or are they just behind the
ball as far as releasing the newer versions to the ftp site? (I'm
assuming the former.)
