I have never seen a node on Linux without memory. I have seen nodes
without processors and without I/O but not without memory.This seems to be
something new?
A node was always defined that way. Search back a few years in the lkml
archives. We may be finding bugs in the implementation, but the
definition has not changed.
Supposing we hot-unplugged all the memory in a node? Or seems to have
happened in this instance is boot with mem=, cutting out memory on that
node.
