This is my method. However, note that stopping GFS unmounts the
volumes,
so you can skip the manual unmount.
Being a Fedora 14 user (at this point), rebooting the cluster node(s)
with shutdown -r|h now has been working fine for me since transitioning
to F14 (should be the same cluster stack as what RHEL 6 uses now, I
believe)
Migrating any rgmanager services off of the node I'm bringing down
first seems to be required (httpd/apache is pretty slow at shutting down
and thus causes my shutdown -r generated umount of the gfs|gfs2 file
systems to fail)

PS: is there a specific reason why the GFS/GFS2 service shutdown option
doesn't do something akin to "fuser -k" for the mountpoints in order to
kill off any processes that would cause the umount to fail? Yes it's
brutal, and certain databases would be a little unhappy, but I'd argue
any db shutdown script that doesn't stall until the DB is actually down
are buggy by definition.
