[gpfsug-discuss] what is mmnfs under the hood

[Ilan Schwarts]

I have gpfs (spectrum scale 4.2.2.0) and I wish to create NFS exports,
I cannot use ganesha NFS.
How do I make NFS exports ? just editing all nodes /etc/exports is enough ?
I should i use the CNFS as described here:

Using user space Ganesha means they have control of the NFS stack, so if something needs patching/fixing, then can roll out new Ganesha rpms rather than having to get (e.g.) RedHat to incorporate something into kernel NFS.
