This could be an issue with etcd rpm. With Systemd, /run is an in-memory tmpfs and is wiped on reboots.

We’ve come across a similar issue in mariadb rpm on CentOS 7: https://bugzilla.redhat.com/show_bug.cgi?id=1538066

If the etcd rpm only creates /run/etcd during installation, that directory will not survive reboots. The rpm should also drop a file in /usr/lib/tmpfiles.d/etcd.conf with contents similar to

d /run/etcd 0755 etcd etcd - -
