Re: Concurrent mount of XFS over SAN

[Heilige Gheist <hgheist@yahoo.com>]

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
