Re: [Linux-cluster] use of netgroup as NFS client resource target?



The pithy ruminations from bergman merctech com on "[Linux-cluster] use of netgroup as NFS client resource target?" were:


I posted this query in April and received no replies, but the need has come up again, so I'm giving it another try.

Does anyone have information about using (NIS) netgroups to define an export list as the NFS client resource?

Currently I've got each NFS client defined as a private resource under the NFS service for each exported filesystem.
Instead of defining each client separately, is it possible configure the cluster resource to export to a netgroup (a list of clients defined and maintained outside of RHCS)? 

I'd appreciate any suggestions on this.

Thanks,

Mark
