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?

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". --- Orlando -- -- Dr Orlando Richards Research Facilities (ECDF) Systems Leader Information Services IT Infrastructure Division Tel: 0131 650 4994 skype: orlando.richards The University of Edinburgh is a charitable body, registered in Scotland, with registration number SC005336. _______________________________________________ gpfsug-discuss mailing list gpfsug-discuss at gpfsug.org<http://gpfsug.org> http://gpfsug.org/mailman/listinfo/gpfsug-discuss _______________________________________________ gpfsug-discuss mailing list gpfsug-discuss at gpfsug.org http://gpfsug.org/mailman/listinfo/gpfsug-discuss
