NFS mount on cluster lock VG

[daalman]

Hello,

Can anyone tell me if there are any risks in defining an NFS mount on a volume group which is also the cluster lock VG?


Thanks !

Hi,

If you build NFS as a package, there is not any risk, otherwise the VG can not be relocked.

Serviceguard was designed to use the cluster lock VG for data too, whether it be NFS-mounted or not. It is safe to use the cluster lock VG/PV for data activity.

Thanks for your comments.

Is it necessary to install the NFS toolkit in this case?

[Kevin Wright]

the NFS toolkit should be used anytime you have an NFS enabled package. It is irrelevant to the cluster lock disk.

It has to be a dedicated device for cluster lock, in order to see that this will be claimed first before cluster is formed..

Thanks and regards

In regards to the previous post, it isn't needed for initial formation of the cluster ... only if a reformation is needed while cluster is up and running.

That being said, it doesn't have to be mounted at that time, just physically available.

Agree... Good point..
Thx

The NFS toolkit (B5140BA) provides sufficient functionality to build a mobile NFS Serviceguard package. This helps the system administrator avoid having to code scripts to do the same thing. The admin merely customizes the scripts with site-specific details and then applies the package. It's a time-saver, if you need one, and cheap at twice the price :)

The HP NFS toolkit is also the only supported way to implement NFS in a robust fashion. In order to do the same thing manually you would need to edit the package template file generated by cmmakepkg in a way which is not supported by HP. Failure to do this will lead to stale NFS mounts.
