Not a solution to the initial problem, but a workaround:
I managed to "fake" the shared device with DRBD. Guests are CentOS 5.3
x86_64, with DRBD 8.3 and OCFS2 1.4
I now have a single filesystem (OCFS2) mounted read/write on two
machines at the same time, with the underlying storage mirrored
real-time over TCP on both machines (via DRBD). I verified, and it's
really read/write on both sides.
Given that the whole thing is virtualized, we're talking here of several
layers of virtualization (OS, then storage...). That's pretty rad. :)
This is enough for me to test the Oracle cluster, but just for the heck
of it I'll see if I can now share a single storage device on both
systems, using the hints provided here. (thanks!)
My host is Windows XP at the moment, which may be an issue. Well,
there's only one way to find out. Very likely I'll upgrade ;-) the host
to Ubuntu 9.10 when it's released this month.
I'll keep y'all posted if I make more progress.
