[Linux-cluster] Help with cluster.conf

[Ben Yarwood]

I think having looked at:

http://sources.redhat.com/cgi-bin/cvsweb.cgi/cluster/rgmanager/src/resources/netfs.sh?rev=1.11&content-type=text/x-cvsweb-markup&cvs
root=cluster

this:

        <netfs options="rw" mountpoint="/mnt/encoded/audio/wav" force_unmount="1" export="/export-path" fstype="nfs" host="hostname"
name="name-of-the-resource"/>

Will try to mount an nfs fs from the remote host and export <host="hostname" export="/export-path"> rather than just specify a
directory to be exported from a local fs.

I've now looked at the nfsclient.sh script and I think I can just specify the export path in that part of the file e.g. as follows:

<resources>
...

<nfsclient name="dmz" path="/mnt/encoded/audio/wav" target="10.0.40.0/24" options="ro,sync"/>

...

</resources>


Can anyone confirm if this is correct?   I'm not sure what will happen as there is no fsid to inherit?


Regards
Ben
