[rdo-list] [TripleO] Newton large baremetal deployment issues

[Justin Kilpatrick]

Hey Charles,

If you want to deploy a large number of machines, I suggest you deploy a
small configuration (maybe 3 controllers 1 compute) and then run the
overcloud deploy command again with 2 computes, so on and so forth until
you reach your full allocation

Realistically you can probably do a stride of 5 computes each time,
experiment with it a bit, as you get up to the full allocation of nodes you
might run into a race condition bug with assigning computes to nodes and
need to pin nodes (pinning is adding as an ironic property that
overcloud-novacompute-0 goes here, 1 here, so on and so forth).

As for actually solving the deployment issues at scale (instead of this
horrible hack) I'm looking into adding some robustness at the ironic or
tripleo level to these operations. It sounds like you're running more into
node assignment issues rather than pxe issues though.
