Re: [gpfsug-discuss] what is mmnfs under the hood

2017-08-06 Thread Greg.Lehmann 
It would be nice to know why you cannot use ganesha or mmsmb.

You don't have to use protocols or CES. We are migrating to CES from doing our 
own thing with NFS and samba on Debian. Debian does not have support for CES, 
so we had to roll our own. We did not use CNFS either. To get to CES we had to 
change OS. We did this because we valued the support. I'd say the failover 
works better with CES than with our solution, particularly with regards failing 
over and Infiniband IP address.

So, in a shortcut, CNFS cannot be used when sharing via CES.
I cannot use ganesha NFS.

Is it possible to share a cluster via SMB and NFS without using CES ?
the nfs will be expored via CNFS but what about SMB ? i cannot use mmsmb..

Re: [gpfsug-discuss] what is mmnfs under the hood

2017-08-06 Thread Simon Thompson (IT Research Support) 
What do you mean by cannot use mmsmb and cannot use Ganesha? Do you 
functionally you are not allowed to or they are not working for you?

If it's the latter, then this should be resolvable. If you are under active 
maintenance you could try raising a ticket with IBM, though basic 
implementation is not really a support issue and so you may be better engaging 
a business partner or integrator to help you out.

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:

Re: [gpfsug-discuss] what is mmnfs under the hood

2017-08-06 Thread Simon Thompson (IT Research Support) 
Under the hood, the NFS services are provided by IBM supplied Ganesha rpms. 
It's then fully supported by IBM, e.g. the GPFS VFS later to handle locking, 
ACLs, quota etc...

Note it's different from using the cnfs support in Spectrum Scale which uses 
Kernel NFS AFAIK. 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.

Mmnfs is a wrapper round the config of Ganesha using CCR to distribute the 
config to the nodes.

Hi guys,

I see IBM spectrumscale configure the NFS via command: mmnfs

Is the command mmnfs is a  wrapper on top of the normal kernel NFS
(Kernel VFS) ?
Is it a wrapper on top of ganesha NFS ?
Or it is NFS implemented by SpectrumScale team ?


Thanks
