Thanks for the pointers. For now I'm going with a single backend with two
NFS shares, so I'll use the tripleo templates for netapp.
For the future, could you point me to the right template / puppet-cinder
code which can create multiple nfs share files for me? Or should I create
my own puppet manifest?
