i was hoping it was a system that allowed me to designate a set of nodes to all have their own local harddisk as an always uptodate cache of the cluster filesystem.
(eg what coda and lustre do)
No offense but i think il stick to mysql for now, as it supports just the functions i need, and with that i can use all the memmory i want.
Thanks anyway.

I don't know the answer offhand, but the user guide can be found here
(http://oss.oracle.com/projects/ocfs2/dist/documentation/ocfs2_users_guide.pdf)
and chop that address down to just the oss.oracle.com to find general
information about all of Oracle's Open Source endeavors.
My guess, since they support shared root, is that its a shared disk solution.

See previous.

Considering that they support Oracle running on OCFS2 (as well as
shared root), I doubt this would be a problem in either case.
As for the mysql question, I'm not sure that Larry would be too happy
with someone running mysql on top of OCFS2. Not that I expect you to
consider it, but there is a "lite" version of Oracle DB that's free
called Express Edition
(http://www.oracle.com/technology/products/database/xe/index.html).
Exactly how scaled back it is, I have no idea, but its Oracle DB and
free - that's at least something.

This would be more a database issue (locking and so forth), but yea.
