GlusterD did start too early. GlusterD is configured to start after network.target. But network.target in systemd only guarantees that the network management stack is up; it doesn't guarantee that the network devices have been configured and are usable (Ref [1]). This means that when GlusterD starts, the network is still not up and hence GlusterD will fail to resolve bricks. While we could start GlusterD after network-online.target, it would break GlusterFS mounts configured in /etc/fstab with _netdev option. Systemd automatically schedules _netdev mounts to be done after network-online.target. (Ref [1] network-online.target). This could allow the GlusterFS mounts to be done before GlusterD is up, causing them to fail. This can be done using systemd-220 [2] which introduced support for `x-systemd.requires` option for fstab, which can be used to order mounts after specific services, but is not possible with el7 which has systemd-208.
