Dave,
That's 100% correct assuming you prohibit a shared access between the
nodes. I didn't point out that we're dealing with filesystem failover
setup.
It's obvious that I can always fall back to the inter-node heart-beat
to ensure that only one node is mounting the filesystem.
I'm just wondering if there's any facility or accepted practice to
enforce it.
Thanks,
Alan
