I've had *horrible* results with heartbeat/pacemaker in general. While
I haven't used it for SGE, I wouldn't even consider it based on my
experiences with it in the past year.
Not trying to start a discussion about heartbeat/pacemaker, as this is
an SGE thread--email me offline if you have questions/comments.
For reference, I'm using a shadow master with success via a shared NFS
backend. The NFS share runs off a fault-tolerant NFS head system (thing
NetApp/EMC type thing). Neither the master or shadow master servers
actually "host" the files.

Hi,
Is it possible to set up a sge shadow master host on a non shared
environment? Here's what we have:
Fully running grid with sge master sharing sge_root over nfs to 10
compute nodes.
We have a spare node that I'd like to use it as master backup in case
of primary master is down.
I understand that I can share nfs to the backup master too and set up
shadow with no problem but when primary hardware fails, nfs will be
useless. You guys have any advice/suggestions?
