Description joshua 2011-05-26 21:58:35 UTC 
Description of problem:

I've got a GFS2 filesystem, and I can share *all* of it via NFS, but I don't want to.  I want to share one subdirectory of it... and RHEL HA doesn't let me.

This would be a nice feature to have, and would make NFS in RHEL HA a lot more flexible.

This enhancement request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux maintenance release.

Product Management has requested further review of this enhancement by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Update release for currently deployed products.

This enhancement is not yet committed for inclusion in an Update release.
Comment 3 Lon Hohberger 2011-05-27 17:24:32 UTC 
It can be done; simply put the full path attribute in to cluster.conf.

I believe luci can do this using 'expert mode'.
Comment 4 Lon Hohberger 2011-05-27 17:28:38 UTC 
ex:

<clusterfs mountpoint="/mnt/1" >
  <nfsexport name="blah" />
    <nfsclient path="/mnt/1/only_to_foo" target="foo" options="..." />
  </nfsexport>
</clusterfs>

The nfsclient resource inherits by default, but you can always override inheritance.

Based on Lon's response I will close this bug. I Cc-ed Steven Levine for doc clarifications.
Comment 6 joshua 2011-05-27 18:14:18 UTC 
Where is expert mode documented?  How does one enable it?
