From a043ba9e9951d091f66d00ed88ad05b66c3f3c63 Mon Sep 17 00:00:00 2001 From: Michael Gugino Date: Mon, 12 Feb 2018 12:22:32 -0500 Subject: Fix etcd scaleup plays This commit ensures that only the proper host groups have sanity checks run during etcd scaleup. This commit also adds additional debugging statements to sanity_checks.py to make it easier to debug when an error occurs.
