If your desired NFS server is on the public network, then you should have the compute nodes there as well. OSCAR does not require you to have a private subnet for your nodes.
As for NIS, I'm not familiar enough to know if you can bind to multiple domains or not. But I would recommend putting your nodes on the public subnet and then just using the main NIS domain on the cluster as well.

Hi,

I havent yet started using OSCAR - but wondered if it would be able
to help me in configuring my setup as described below. If it does
then looks like I'm coming over to OSCAR :-)

Thanks

Subject: Private Network Cluster - NFS Storage on public network

Hi,

I have an existing LAN which houses all my main servers and storage
(NFS on solaris mostly). These are all configured in one NIS domain.

I have recently gained a small cluster which is configured on it's
own private LAN - class C with the master node sitting on both the
main public (eth1) and the private cluster network (eth0). The
cluster is configured as a small seperate NIS domain.

Currently I have a medium sized disk sitting on the master node and
users scp their data files onto this and write their data back to it
- however with the increasing size of their data and the amount of
support calls it generates this is becoming quite unfeasible and as
they have large amounts of storage available on the main network I'd
like to be able to utilize this as their homeares on the cluster.

Can anyone let me know how I'd go about configuring the cluster side
if things so that it will mount the users homearea from the main LAN
and make this available to all the nodes in the private cluster LAN.

If I could use the userid and passwd from the main NIS domain even
better - can the master node be bound to 2 NIS domains?

Any help on this - or a better way forward would be greatly
appreciated - if anyone has some examples on best cluster practise
I'd appreciate that as well.

Incidently I searched the web and came across
http://oscinfo.osc.edu/training/beo/using-cluster.pdf in which they
seem to talk about doing exactly what I'm trying to do above (ie
main storage mounted to cluster nodes) - but don't describe how.

Thanks in advance
Surinder
