Just make the new VMs NFS clients, no? It's so much simpler and the
performance is not much less. But you do need to run CNFS in the GPFS
cluster.

Yes, what about the random name nature of a vm image?
For example I spin up a new vm, how does it join the gpfs cluster to be able to
use nsd protocol?
And how about attaching to the netowkrk as neutron networking uses per tenant
networks, so how would you actually get access to the gpfs cluster?

Subject: Re: [gpfsug-discuss] GPFS inside OpenStack guests
technically there are multiple ways to do this.
1. you can use the NSD protocol for this, just need to have adequate Network
resources (or use PCI pass trough of the network adapter to the guest)
2. you attach the physical disks as virtio block devices
3. pass trough of the Block HBA (e.g. FC adapter) into the guest.
if you use virtio you need to make sure all caching is disabled entirely or you
end up with major issues and i am not sure about official support for this, 1
and 3 are straight forward ...

Hi folks,
Does anyone have experience of running GPFS inside OpenStack guests, to connect to an
existing (traditional, "bare metal") GPFS filesystem owning cluster?
This is not using GPFS for openstack block/image storage - but using GPFS as a "NAS"
service, with openstack guest instances as as a "GPFS client".
