[Linux-cluster] NFS Exports in rgmanager

[Nick Couchman]

I'm attempting to set up fail-over NFS services on my RHCS cluster and have a question about the NFS export and NFS client resources.  In our environment, we have a few occasions where we don't want to export the entire volume to a client, we just want to export a certain directory on the volume.  So, for example, by default, when you set up a GFS Filesystem (let's say it's mounted at /mnt/Vol1), an NFS export resource (we'll call it Share1), and an NFS Client Resource (client1 with options rw,root_squash), the entire contents of /mnt/Vol1 is exported to the client.  In our case, we have a directory - /mnt/Vol1/Dir1/ThisDirectory - that we need to export to a client, and we only want the client to have access to that directory.  Is this possible in rgmanager?  If so, how do I go about it?  If not, can someone suggest some alternatives, aside from completely manually managing the NFS stuff with RHCS?  If the answer to that is that I must do it manually, maybe someone can consider adding in a "Directory" resource to rgmanager?
 
Thanks,
Nick
