CPU & Memory HACMP and NFS client

Hi all,

I know there are topics regarding this but didn't found the answer.
I have two node HACMP cluster and the application that runs there relies on some NFS mount. The NFS server is some 3rd box that have nothing to do with the cluster.

How can I mount the NFS shares only on the active node? I was reading about cross-mounting but it's different. Do I have to modify the start/stop scripts or there's more friendly method?

I'm thinking about mounting permanently the NFS shares somewhere and then exporting that local directory and mounting again with HACMP, but don't like this idea.

AIX 5.3

Any thoughts?
Thank you

Easiest way is just to add NFS mount/unmount to start-stop scripts

Probably.. I was just wondering if there's more fancy approach.

Code:
smitty cm_change_resources_for_a_rg_select

there you can specify nfs filesystems to be part of your resource group


from the smit help:
All nodes in the resource chain will attempt to NFS-mount these filesystems


so this might not solve your issue

Check automount.

NFS will then be mounted only when the share is being accessed / used.

Hope that helps.

funksen, but this is for cross-mount (when the NFS server is the node).

Peasant, that could work Smilie
But for now I'll try to find a solution within HACMP.
