re[2]: Exporting xfs over nfs

[Greg Freemyer <freemyer@NorcrossGroup.com>]

Eric,

His problems are likely more generic than just XFS / NFS integration.

NFS (on any filesystem) has not historically been very compatible with fail-over clustering  and gives the stale handle message after a fail-over.

As Horms said, there has been a lot of discussion and development related to this recently.

The heartbeat mailing lists archives should cover this topic in detail.  (80+ messages at last count)

FYI: 
It requires a fair bit of effort, but it can be accomplished.

To my knowledge there is not a out-of-the-box solution, and neither is there a nice clearly written how-to.
