This commit fixes an error log caused by the strict reconfig checking option. Before: 14:21:38 etcd2 | 2015-11-05 14:21:38.870356 E | etcdhttp: got unexpected response error (etcdserver: re-configuration failed due to not enough started members) After: log 13:27:33 etcd2 | 2015-11-05 13:27:33.089364 E | etcdhttp: etcdserver: re-configuration failed due to not enough started members The error is not an unexpected thing therefore the old message is incorrect.
