RE: 10.2.0.2 EE RAC, RHEL4 and LVM2 support?

The only slogan I can come up with for this is
"The land of the free and the brave".  Folks, GFS
forces you to have a node that does not host RAC instances
dedicated to their lock manager.... and then that is a
single point of failure...but I hear you can cluster the
lock manager...is that 4 nodes for 2 node RAC?

All this central lock manager madness is just crazy. There
are fully distributed, symetric, resilient, journalled
CFS offerings out there. One runs on VMS and the
other runs on Linux and Windows. I can tell you where
to get the latter :-)

How "free" is that open source stuff afterall?
